ABB 2CSF202001R3900 Residual Current Circuit Breaker
Product Description :
- It is a safety device used in electrical systems to prevent electric shock or fire caused by a leakage current. It detects any imbalance between the live (phase) and neutral wires, which could occur if there is a fault in the wiring or if someone comes into contact with a live part.
- It helps protect against electric shock, especially in areas with high moisture or wet conditions like bathrooms or kitchens.It constantly monitors the current flowing in and out of a circuit.If there’s a difference (i.e., some current is leaking to the ground), the RCCB quickly cuts off the power — usually within milliseconds.It reacts to earth faults or unintended paths, not to overloads or short circuits (that’s the job of an MCB).
