3Pole Magnetic Motor Contactor With Timer Fixed Install DC Power

GENERAL

STSP 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.

Magnetic contactor is common used in automation industry for motor control application. It is function basically like “relay”. The power source into the coil of winding, it like the solenoid operation. It can deliver a big ampere to the loads and very long lasting and high durability.

When the power is “on”, it energized the coil and make plunger move and the switch contact is change from normally open to closed position. It allowed the current move from input terminal to output terminal. Then if we connected to the 3 phase motor, it will running
