YCC7 4P Contactor

Product Detail

General

The YCC7 4P series contactor has four main contacts, which can control two independent load circuits or perform on-off control on three-phase four wire circuits. In the case of a three-phase four wire system, both the phase and neutral wires need to be cut off when the power is cut off.
