Jawabannya tidak sesederhana itu, karena tergantung pada jenis circuit breaker di fasilitas Anda. Seperti yang dinyatakan oleh National Electrical Code (NEC) tahun 2020, low-voltage power circuit breaker, medium-voltage circuit breaker, dan high-voltage circuit breaker diperbolehkan untuk direstorasi sementara molded case circuit breaker (MCCB), GFCI circuit breaker, dan AFCI breaker tidak boleh diperbarui menurut NEC Article 210.15 dan Section 240.88. Oleh karena itu, perbedaan ini sangat penting bagi manajer pabrik, kontraktor listrik, dan insinyur pemeliharaan yang perlu menyeimbangkan biaya dengan keselamatan dan kepatuhan terhadap kode.<\/p>\n<blockquote><p><strong>Jawaban cepat:<\/strong> Circuit breaker yang dapat diperbarui meliputi low voltage power circuit breaker, medium voltage power circuit breaker, dan high voltage circuit breaker. Molded case circuit breaker tidak dapat diperbarui seperti yang dinyatakan oleh NEC 240.88(A)(1), dan juga circuit breaker yang menyediakan perlindungan GFCI, AFCI, atau GFPE dilarang oleh NEC 210.15. Produsen terkemuka yang menawarkan perbaikan pabrik meliputi: Eaton, ABB, dan Schneider Electric \/ Square D. Proses perbaikan mematuhi aturan dan regulasi IEEE C37.59 dan NEMA AB 4.

The important measurements taken include contact resistance (in millivolts) insulation resistance, mechanical operating effort and dimensions. The information obtained is documented.<\/p>\n<h3>Step 2: Complete Disassembly<\/h3>\n<p>The disassembly of the breaker is complete and the breaker has been taken apart into its components including: the operating system, the arc chute, the insulation barrier, frame and other systems. This is the stage where one identifies flaws such as, the faulty drive link, or misaligned contacts, damaged insulation that makes the whole device liable to failure when the fault is detected.<\/p>\n<h3>Step 3: Component-Specific Cleaning<\/h3>\n<p>Various types of materials need various types of cleaning processes. The non-current components are cleaned thoroughly in such a way that no foreign material is left while dielectric and structural characteristics are preserved. The current components are cleaned without damaging the original plating. Contact surfaces are regenerated so that metallurgy and contact pressure play their role properly.<\/p>\n<h3>Step 4: Inspection &amp; Part Replacement<\/h3>\n<p>All parts should be checked for cracks, deterioration, rust, and size accuracy. Parts that have worn out are replaced by new OEM parts, while parts that are not in production anymore will need to be replaced with reverse-engineered components which must comply with standards stated in IEEE C37.59. Such components may require verification in strict laboratory conditions such as examples of high-power testing. The typical substitutes for the worn parts may be springs, contacts, shunts, and bushing.<\/p>\n<h3>Step 5: Re-Lubrication<\/h3>\n<p>All outdated lubricants have been eliminated, and the machine and connection points are relubricated using grease specified by the manufacturer. One of the key reasons that circuit breakers fail is due to inappropriate lubrication \u2014 stiff mechanisms slow down the process of trouble clearing, which results in much higher arc flash incident energy.<\/p>\n<h3>Step 6: Reassembly to OEM Specifications<\/h3>\n<p>In the process of reassembling the breaker, the OEM documentation is utilized. However, if OEM information is not available, for instance if the original manufacturer is defunct, Eaton will instead use the centralized Pow-R-DB database of records from similar breakers that are proven to give desired outcomes.<\/p>\n<h3>Step 7: Final Testing<\/h3>\n<p>The rebuilt circuit breaker will go through conclusive testing as per IEEE and NEMA guidelines including:<\/p>\n<ul>\n<li>Insulation resistance assessment<\/li>\n<li>Contact resistance test (millivolt drop)<\/li>\n<li>Mechanical operation assessment (open-close timing)<\/li>\n<li>Overcurrent trip test (long-time, short-time, instantaneous trip)<\/li>\n<li>Dielectric withstand assessment<\/li>\n<\/ul>\n<h3>Step 8: Documentation &amp; Labeling<\/h3>\n<p>The production of the test report occurs to establish a contrast between &#8220;as received&#8221; and &#8220;final&#8221; test findings, supported by information mentioning all the fixed components. The circuit breaker is provided with a traceability label signifying it as reconditioned, which indicates the name as well as the date of the reconditioning firm. The circuit breaker is operational again.<\/p>\n<h2>When to Choose Reconditioning vs. Replacement<\/h2>\n<p>The decision to recondition or replace depends on breaker type, age, criticality, and cost.

Here are the requirements that need to be checked before installation of a reconditioned circuit breaker:<\/p>\n<ul>\n<li>Labeling: The reconditioned circuit breaker is marked &#8220;Reconditioned&#8221; with the name of the reconditioning company and date.<\/li>\n<li>Test: Get a complete report evidencing &#8220;as received&#8221; and &#8220;final&#8221; test results along with a list of parts replaced.<\/li>\n<li>Certification: In case UL certification is required, verify that the circuit breaker is marked with UL Mark with &#8220;Rebuilt&#8221; or &#8220;Reconditioned.&#8221;<\/li>\n<li>Approval by AHJ: The Authority Having Jurisdiction (electrical inspector) may need proof of reconditioning by a certified company &#8211; stay prepared.<\/li>\n<li>Warranty: Verify the warranty conditions and length (Eaton: 3-year; ABB: 1-year; others vary).<\/li>\n<li>Traceability: The reconditioning company should do recordkeeping linked to the circuit breaker serial number for future reference.<\/li>\n<li>Do not install the reconditioned circuit breaker in the life-safety circuit unless the AHJ and your insurance agent approved the installation.<\/li>\n<\/ul>\n<p>Also, OSHA 29 CFR 1910.334(b)(2) states that once the circuit is de-energized with the protective device it is not allowed to re-energize it manually until it is determined that the equipment and circuit can be safely energized.<\/p>\n<h2>Pertanyaan yang Sering Diajukan<\/h2>\n<h3>What is a reconditioned circuit breaker?<\/h3>\n<p>A reconditioned power circuit breaker refers to a power circuit breaker which has undergone a restoration process at a factory-authorized facility. According to the requirements set forth by IEEE C37.59, the entire activity involves an incoming inspection, complete disassembly, cleaning of components, replacement of parts, reapplication of lubricants, reassembly of components according to OEM specifications, and final testing. In addition, the circuit breaker must be labeled as being reconditioned with the name and date of the reconditioning firm, and the original listing had to be taken off due to the NEC requirements.<\/p>\n<h3>What are type B, type C, and type D circuit breakers?<\/h3>\n<p>Types B, C, and D are classifications of MCBs regarding tripping characteristics and not types of circuit breakers classified according to NEC 240.88. Type B circuit breakers trip at three to five times the rated current; these are used in residential applications for circuits with purely resistive loads. After that, we have Type C circuit breakers, which trip at five to ten times the rated current and are used in commercial and industrial electrical systems, as well as circuits with inductive loads, such as fluorescent lights and small motors. The third type is Type D MCBs, which trip at ten to twenty times the rated current and deal with inrush current in transformers, large motors, or welding machines. All the above types of breakers are miniature circuit breakers, molded-cased, and cannot be reconditioned in accordance with NEC 240.88(A)(1).<\/p>\n<h3>Are molded case circuit breakers permitted to be reconditioned?<\/h3>\n<p>Based on the NEC Section 240.88(A)(1) in the year 2020, it is not allowed to refurbish molded- case circuit breakers. MCCBs come as sealed units hence breaking the seals means losing the UL listing and warranty of the manufacturer. Though there is guidance for inspection and preventive maintenance of MCCBs in the NEMA AB 4 guidelines, it is not equal to reconditioning. Routine maintenance is fine but disassembly or modification of the internal structure of the MCCB is not accepted.<\/p>\n<h3>Which type of equipment is not allowed to be reconditioned according to article 210?<\/h3>\n<p>The NEC states under Article 210.15 that there are three kinds of equipment that are not permitted to be reconditioned. These include (1) equipment that supplies personnel with ground-fault circuit interrupting (GFCI) protection, (2) equipment that supplies arc-fault circuit interrupting (AFCI) protection, and (3) equipment that provides ground-fault protection for equipment (GFPE). The reason for these prohibitions is that the devices that are required to be reconditioned are also safety critical devices that possess calibration and sensitivity requirements that cannot be assured even after they are reconditioned. Thus, if any of the reconditioned devices (GFCI, AFCI, or GFPE) fails to trip at the required threshold, then a life hazard will be created. Also, the NEC states that molded circuit breakers cannot be reconditioned by Section 240.88(A)(1) nor can the electronic trip units of low-voltage power circuit breakers be reconditioned according to Section 240.88(B).<\/p>\n<h2>Referensi<\/h2>\n<ul>\n<li><a href=\"https:\/\/www.nfpa.org\/codes-and-standards\/nfpa-70-standard-development\/70\" target=\"_blank\" rel=\"nofollow noopener\">NFPA 70 \u2014 National Electrical Code (NEC) 2020, Articles 210.15 and 240.88<\/a><\/li>\n<li><a href=\"https:\/\/www.nema.org\/standards\/view\/guidelines-for-inspection-and-preventive-maintenance-of-molded-case-circuit-breakers-used-in-commercial-and-industrial\" target=\"_blank\" rel=\"nofollow noopener\">ANSI\/NEMA AB 4-2023 \u2014 Guidelines for Inspection and Preventive Maintenance of Molded Case Circuit Breakers<\/a><\/li>\n<li><a href=\"https:\/\/standards.ieee.org\/ieee\/C37.59\/10366\/\" target=\"_blank\" rel=\"nofollow noopener\">IEEE C37.59-2018 \u2014 Standard for Reconditioning Power Switchgear Equipment<\/a><\/li>\n<li><a href=\"https:\/\/www.shopul.com\/product\/ul-489\" target=\"_blank\" rel=\"nofollow noopener\">UL 489 \u2014 Standard for Molded-Case Circuit Breakers, Molded-Case Switches and Circuit Breaker Enclosures<\/a><\/li>\n<li><a href=\"https:\/\/www.ul.com\/news\/reconditioned-electrical-equipment-2020-nec-guide\" target=\"_blank\" rel=\"nofollow noopener\">UL \u2014 Reconditioned Electrical Equipment: A 2020 NEC Guide<\/a><\/li>\n<li><a href=\"https:\/\/www.eaton.com\/us\/en-us\/catalog\/services\/electrical-distribution-services\/class-1-reconditioning.html\" target=\"_blank\" rel=\"nofollow noopener\">Eaton \u2014 Class 1 Circuit Breaker Reconditioning for Low- and Medium-Voltage Power Circuit Breakers<\/a><\/li>\n<li><a href=\"https:\/\/new.abb.com\/service\/service-centers\/breaker-refurbishment-services\" target=\"_blank\" rel=\"nofollow noopener\">ABB \u2014 Service Center Breaker Refurbishment Services<\/a><\/li>\n<li><a href=\"https:\/\/www.se.com\/us\/en\/work\/services\/field-services\/electrical-distribution\/\" target=\"_blank\" rel=\"nofollow noopener\">Schneider Electric \u2014 Electrical Distribution Modernization and Upgrade Solutions<\/a><\/li>\n<li><a href=\"https:\/\/www.pearl1.org\/\" target=\"_blank\" rel=\"nofollow noopener\">PEARL \u2014 Professional Electrical Apparatus Reconditioning League<\/a><\/li>\n<\/ul>\n<p>Reconditionable circuit breakers include low-voltage, medium-voltage, and high-voltage circuit breakers of the draw-out, field-serviceable type that are commonly used in substations and switchgear. The design of the circuit breaker makes use of replaceable contacts, easily accessible mechanism, and interchangeable trip units allowing practical reconditioning in compliance with NEC 240.88. Major manufacturers such as Eaton, ABB, and Schneider Electric offer the reconditioning service according to IEEE C37.59 standards guaranteeing warranties comparable to what new equipment receives.<\/p>\n<p>On the other hand, molded-case circuit breakers, GFCI devices, AFCI devices, and GFPE equipment are unconditionally prohibited from being reconditioned as per NEC 210.15 and 240.88 and must be replaced if broken. The 2020 NEC has made it clear that circuit breakers designed to be maintained may be maintained while sealed safety-critical breakers may not. When opting for reconditioning or replacement, identify the type of circuit breakers first and compare the cost of failure, so you are able to understand what is worth doing more \u2014 reconditioning or replacing the circuit breaker.<\/p>","protected":false},"excerpt":{"rendered":"<p>In case your facility uses outdated switchgears, you may wonder whether you can refurbish your circuit breakers or should obtain brand new gadgets.
