General This is B Type Residual Current Circuit Breaker
Type B RCCBs, in addition to normal AC, can detect high frequency AC and pure DC earth leakage currents. Reducing the risk of fire and/or electrocution through automatic disconnection of the electrical supply relies on the selection of the correct type of RCCB.

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, tertiarysector and industry
- 1.2 Selection Detectable wave form B class Tripping is ensured for sinusoidal AC residual currents pulsed DCresidual currents,alternatingresidual sinusoidal currents up to1000Hz, pulsating direct residual currents and for smooth directresidual currents, whether applied suddenly or increasing slowly. Tripping sensitivity 30mA -additional protection against direct contact. Tripping time Instantaneous
It ensures instantaneous tripping (without time- delay).
