Scope of application:
JC-II residual current action protector is a suitable product developed based on the renovation of rural low-voltage power grids. It provides comprehensive indirect protection and cuts off the power supply to ensure safety in the event of power grid faults such as wire falling into water or live wires. A leakage protection combination device consisting of a protector and an AC contactor is suitable for use in low-voltage (380V/200V) TT distribution systems where the neutral point of the power supply is directly grounded. It serves as the overall protection or sub protection for multi-level line protection.
