ID-A Residual Current Operated Circuit Breaker Without over-current protection (Magnetic)
Control electric circuits.
Protect people against indirect contacts and additionalprotection 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. General
1.1 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 I△n＜50/R，to provide protection against indirect
contacts;
300mA-protection against indirect contacts, as well as fire harzard.
Tripping time
Instantaneous
It ensures instantaneous tripping (without time-delay).
Short time delay G
It ensures any tripping at least 10ms.
Selective S
It ensures total discrimination with a nonselective RCD placed downstream.
