Din Rail B Type Earth Leakage Current Breaker DC RCCB RCD 4P 40A 63A 30mA 300mA Type B RCD 6KA 1Pcs(2P,40A 300mA)

Circuit Breaker PanelsGeneralIt is GYL9 B type RCCB Magnetic 2P 4P 40A 63A 30mA 100mA 300mAType 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 ExampleEV & PV installations Frequency converters UPS installations Highfrequency power converters Building site power supply cabinets11 FunctionControl electric circuitspeople against indirect contacts and additionalprotection against direct contactsinstallations 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 currentswhether applied suddenly or increasing slowlyTripping sensitivity30mA additional against direct contact.Tripping timeInstantaneousIt ensures instantaneous tripping (without time- delay).Technical Data OF Type B RCDCompany Information
