Product Description

General

***It 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, High-frequency power converters, Building site power supply cabinets

1.1 Function 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 1.2 Selection Detectable wave form B class 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. Tripping sensitivity 30mA -additional protection against direct contact. Tripping time Instantaneous

It ensures instantaneous tripping (without time- delay).
