Electromagnetic leakage protector PR8NM 6kA RCBO 16-100A circuit breaker
The Electromagnetic Circuit Breaker Have Following Advatages:
1. Control electric circuits
2. Protect people against indirect contacts and additional protection against direct contacts
3. Protect installations against fire hazard due to insulation faults
4. Residual current circuit breakers are used in housing, tertiary sector and industry
5. Support 35mm Din-rail installation
Tripping sensitivity:
♦ 30 mA--additional protection against direct contact
♦ 100mA--co-ordinated with the earth system according to the formula In＜50/R, to provide protection against indirect contacts
♦ 300mA, protection against indirect contacts, as well we fire hazard

Selection:
♦ Detectable wave form
♦ AC type
♦ A type
RCCB for which tripping ensured for residual sinusoidal alternating currents and residual pulsating direct currents, whether suddenly applied or slowing rising, Symbol
Tripping time:
♦ Instantaneous: Instantaneous tripping can be ensured (without time-delay)
♦ Short time delay : Any tripping can be ensured at least 10ms
♦ Selective : Total discrimination with a nonselective RCD placed downstream are ensured.
