Used in the TT, TN-S ground system. Overload, short circuit, current leakage protection.
◆ The residual current action function is independent of the main line voltage with more reliable performance.
◆ For normal opening or fault protection tripping of the circuit breaker, the phase line and neutral line are both in the off
◆ state to avoid harm caused due to the charged neutral line faults.
◆During the connecting and breaking operation, first connect and then break the neutral
◆ line with the overload, short circuit and current leakage protection functions - full protection functions.
◆ Dual-function terminals, with convenient and reliable wiring.
◆The TH35mm standard installation rail is supported.
