Magnetic 3TF Series 3P AC contactor 24V 120V 240V 480V 220V 3TF52
Applications:
3TF power contactors are suitable for switching and controlling squirrel cage and slip-ring motors as well as other AC loads,
such as solenoids, capacitors, lighting loads, heating loads and transformer loads.
Standards:
Contactors conform to IS/IEC 60947-4-1. They also carry the CE mark.
Coordinated feeder:
Contactors and bi-relays have been tested for type-2 coordination at Iq = 50kA, 415V AC, 50Hz as per IS/IEC 60947-4-1, for both
fuse protected as well as fuseless motor feeders.
