Residual Current Circuit Breaker
Residual Current Operated Circuit Breaker without over-current protection(Magnetic)
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
30mA -additional protection against direct contact;
100mA-co-ordinated with the earth system according to the formula IΔn <50/R,to provide protection against indirect contacts;
300mA-protection against indirect contacts,as well as fire harzard.
