ABB RCCB/ELCB 40A 4P 300MA 40A/0.3/4P BMFW440/AC300 1SYF604062R3400 FORMULA
- A residual current circuit-breaker is an amperometric protection device which trips when there is a leakage of current to earth.
- RCCB is the safety device to detect earth leakage current and trip the circuit
- Sensitive only to earth fault current, therefore they have to be connected in series with a MCB or a fuse to protect them against over-currents and short-circuits
- RCCB is the safety device to detect earth leakage current and trip the circuit
