NXL-63 1. General
1.1 Function
Control electric circuits. Protect people against indirect contacts and additional protection against direct contacts. Protect installations against fire hazard due to insulation faults. Residual current circuit breakers are used in housing, tertiary sector and industry. 1.2 Selection Detectable wave form AC class Tripping is ensured for slowly increasing sinusoidal AC residual currents. A class Tripping is ensured for sinusoidal AC residual currents and for pulsed DC residual currents, whether applied suddenly or increasing slowly. Tripping sensitivity 10mA - precision instrument leakage protection and bathroom use. 30mA - additional protection against direct contact. 300mA - protection against indirect contacts, as well as fire hazard. Tripping time Instantaneous It ensures instantaneous tripping (without time-delay)
