Industrial AC Electric Contactor 220V 110A 1NO+1NC Protector
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
