Where it is used

Use it in home and office distribution boards, wet areas, labs, hospitals and factory lighting circuits. A 30mA RCCB protects people from electric shock. 300mA units protect installations against fire caused by earth leakage. See all items in our Residual Current Circuit Breakers (RCCB) range.

How to choose the right one

Pick 30mA for personal protection and 300mA for fire protection at the main board. Use 2P for single-phase and 4P for three-phase supply. Always install an MCB or MCCB upstream, because an RCCB does not protect against overload.
