Air Circuit Breaker FAQ

Questions About Air Circuit Breakers?

Choosing the right air circuit breaker requires matching rated current, voltage, breaking capacity and certification requirements. Below are common questions from industrial power distributors, EPC contractors and project buyers.

How do I choose the right ACB for my project?
The right ACB depends on rated current (630A–6300A), system voltage (AC 400V / 690V), breaking capacity (up to 120kA), pole configuration (3P / 4P) and installation type (fixed or drawout). Buyers should confirm the load profile, protection requirements and installation environment before ordering.
What specifications should I confirm when sourcing ACB products?
Key specifications include rated current, rated voltage, breaking capacity, number of poles, trip unit type (thermal-magnetic or electronic), mounting style, communication options (RS485 / Modbus) and compliance standards. These parameters should match the switchgear design and the requirements of the destination market.
Can ACB products be customized for OEM projects?
Yes. Manufacturers can provide OEM and ODM solutions including ratings, trip units, mounting options, accessory configurations, branding and labeling. Custom configurations help distributors, switchgear manufacturers and EPC companies meet different regional standards and project requirements.
What certifications should I check when sourcing ACB products?
International power distribution projects typically require compliance with relevant safety and quality standards. Depending on the target market, buyers may request certifications such as CE, TUV, CB, UL, IEC 60947-2 compliance and RoHS. Certification requirements should be confirmed according to the destination country and project specifications.
