B Type RCCB Residual Current Circuit Breaker DC ELCB 2P 4P 40A 63Amp 30mA 100mA 300mA Type B 6KA RCD 1Pcs(4P 63A 300mA)

Circuit Breaker PanelsIt is GYL9 B type RCCB Magnetic 2P 4P 40A 63A 30mA 100mA 300mA**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.Application Example: EV & PV installations Frequency converters UPS installations Highfrequency power converters Building site power supply cabinets11 FunctionControl electric circuitsProtect people against indirect contacts and additionalprotection against direct contactsProtect installations against fire hazard due to insulation faultsResidual current circuit breakers are used in housing tertiarysector and industry12 SelectionDetectable wave formB classTripping 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.Tripping sensitivity30mA -additional protection against direct contact.Tripping timeInstantaneousIt ensures instantaneous tripping (without time- delay).
