Flame Retardant 3 Pole Ac Contactor ST1LK With Overload Protection
General
ST1LK Series AC Contactor is suitable for using in the circuits the
rated voltage up to 660V AC 50Hz or 60Hz, rated current up to 95A,
for making & breaking, frequently starting & controlling
the AC motor. Combined with the auxiliary contact block, timer
delay & machine- interlocking device etc, it becomes the delay
contactor, mechanical interlocking contactor, star-delta starter.
With the thermal relay, it is combined into the electromagnetic
starter. The Contactor is produced according to IEC 60947-1.
