General
- TPCH3 series AC contactor is designed for remote switching and control in AC 50/60Hz systems, with rated voltage up to 400V and rated current up to 100A.
- The main contactor is suitable for AC-1 and AC-7a loads such as resistive heating, household appliances, and other light/low-inductive loads, and can also be used for controlling small motors.
- This contactor is not intended to interrupt short-circuit currents, so an appropriate short-circuit protective device must be installed in the circuit.
