B Type circuit breaker
***It is B type RCCB***
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.
EV & PV installations
High-frequency power converters
Building site power supply cabinets
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, tertiarysector and industry
Detectable wave form
Tripping is ensured for sinusoidal AC residual currents pulsed DCresidual currents,
alternating residual sinusoidal currents up to1000Hz, pulsating direct residual
currents and for smooth directresidual currents, whether applied suddenly or increasing slowly.
30mA -additional protection against direct contact.
It ensures instantaneous tripping (without time- delay).
