Used in the TT, TN-S ground system. Overload, short circuit, current leakage protection.
◆ Class AC: Ensure the tripped RCCB for the residual sinusoidal AC current suddenly applied or rising slowly;
◆ Class A: Ensure the tripped RCCB for the residual sinusoidal AC current and residual impulse DC current suddenly applied or rising slowly;
◆ Capable of detecting the leakage current, opening, closing and isolating the entire circuit, to be used with the upper circuit breaker in absence of the short circuit and overload protection functions; high level of anti-interference performance;
◆ 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 current leakage protection function.
◆ Dual-function terminals, with convenient and reliable wiring.
NDL6M-100 series of residual current action switch has obtained China Compulsory Certification (CCC) for products and CE certification.
