GYL9 A-SI Type Time Delayed RCD RCCB ELCB Electromagnetic Circuit Breaker 2P 4P 40A 63A 30mA Type A-SI Super Immunised 1Pcs(TypeA-SI 2P 63A 30mA)

Circuit Breaker PanelsIt is TypeA-SI Time Delayed RCD RCCB ELCB 2P 4P 40A 63A 30mA Earth-Leakage Protection Class : type A-SI (Super Immunised)Type A RCD Features:Tripping is ensured for sinusoidal, alternating residual currents as well as for pulsed DC residual currents, whether they be quickly applied or slowly increase.Application: loads with electronics, rectifiers, instruments.Type SI RCD Features: It's designed to avoid nuisance tripping or non-tripping in case of polluted network, lightning effect, high frequency currents, RF waves, etc.SI type RCDs present a small tripping delay (80s~500s), allowing to let pass this transient current without nuisance tripping. In certain cases, aspects of the environment can disturb the correct operation of RCDs:"nuisance" tripping: Break in power supply without the situation being really hazardous. This type of tripping is often repetitive, causing major inconvenience and detrimental to the quality of the user's electrical powersupply.Non-tripping, in the event of a hazard. Less perceptible than nuisance tripping, these malfunctions must still be examined carefully since they undermine user
