Low Voltage AC Electric Contactor Switch SC32 50A 690V 3poles 1NO Or 1NC
Application:
SC series AC contactor (hereinafter contactor) is suitable for using in the circuits up to the rated voltage 690V AC 50 HZ or 60 HZ , rated current up to 95A, for making, breaking, frequently starting & controlling the AC motor. Combined with the thermal relay, it becomes the electromagnetic starter for protecting the overload circuits.
This series contactor complies with GB 14048, IEC60947-4-1
General:
Ambient air temperature: ≤-5℃--+40℃
Altitude: ≤ 2000m;
Pollution degree: Class 3
Installation category:III
Protection degree: IP20
Feature: Small volume, light weight, less power loss, long life, safe and reliability
Application: Auxiliary contacts block, time relay, current-limited contacts block, thermal relay, etc.
Installation: 35mm din rail (SC09~95), 75MM dil rail (SC40~95), screws
