NL1-63 4N 40A 30mA A-type AUX

CHINT NL1 Residual Current Operated Circuit Breaker without Over-current Protection (Magnetic). Protect people against indirect contacts and additional protection against direct contacts and protect installations against fire hazard due to insulation faults. Residual current circuit breakers are used in housing, tertiary sector and industry.

Detectable wave form A: Tripping is ensured for sinusoidal AC residual currents and for pulsed DC residual currents, whether applied suddenly or increasing slowly.

Tripping sensitivity 30mA – additional protection against direct contact.
