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.
