Ikhtisar Produk

The all-new EXC7 series AC contactors feature a novel design and a compact structure.This series is primarily used for the frequent starting and control of AC motors and for remote circuit switching; it can also be combined with a suitable thermal overload relay to form an electromagnetic staƑer.

Compliant with standards: IEC60947-1, IEC60947-4-1.

Parameter Teknis Utama

• Rated workingcurrent:9-95A;
• Rated workingvoltage:220Vto 69OV;
• Tegangan isolasi terukur: 690V;
• Polarities:3P
• Metode pemasangan: rel dan sekrup

Kondisi Kerja dan Kondisi Pemasangan

Instruksi Penggunaan di Lingkungan Suhu Ekstrem

• The GB/T 14048.1 standard speciƍes the normal operating ambient temperature range for the product; performance remains unaffected when the product is used within this range.
• When the operating ambient temperature exceeds +40°C, the permissible temperature rise limit must be adjusted downward. In such cases, the rated operating current must be reduced, and the number of contactors installed in standard assemblies must be limited; failure to do so may result in product damage, reduced seƒice life, compromised operational reliability, and an impact on the product’s operating range.
• When the operating ambient temperature falls below -5°C, consideration must be given to the fact that greases used for insulation and lubrication may solidify at low temperatures, potentially causing product malfunction. Therefore, manufacturers and users should consult regarding design or application requirements.
• The table below lists the derating factors for rated operating current when the rated operating voltage remains constant and the operating ambient temperature exceeds 55°C.

• +55°C to +70°C: The pick-up voltage range for the AC contactor is (90%–110%)Us. The (70%–120%)Us range represents test results obtained under cold-state conditions at an ambient temperature of 20°C.
• The following table lists the correction factors for rated impulse withstand voltage and rated operating current when the rated operating voltage remains unchanged and the altitude exceeds 2000 m:

Instructions for Use in Abnormal Temperature Environments

• The GB/T 14048.1 standard speciƍes the normal operating ambient temperature for the product.When used within the normal operating ambient temperature range, the product’s peƐormance is not signiƍcantly affected.
• When the operating ambient temperature exceeds +40°C, it is necessaƔ to consider derating the permissible temperature rise limit. In such cases, the rated operating current must be reduced, and the number of contactors installed in standard assemblies must be decreased. Failure to do so may result in product damage, reduced seƒice life, diminished operational reliability, and an impact on the product’s operating range.
• When the operating ambient temperature falls below -5°C, consideration must be given to the fact that greases used for insulation and lubrication may solidify at low temperatures, potentially causing product failure. Therefore, the manufacturer and the user should consult regarding design or usage requirements.
• The table below lists the rated operating current derating factors for instances where the rated operating voltage remains constant but the operating ambient temperature exceeds 55°C.

• +55°C~+70°C: The pull-in voltage range of the AC contactoris(90%~110%)Us.The range of(70% ~120%)Us is the testresult obtained under the condition of cold state atnormaltemperature of 20°C
• The following table provides correction factors for the rated impulse withstand voltage and rated workingcurrent when the altitude exceeds 20oom with the rated working voltage remains unchanged:
