Schneider RCBO 20A 1P+N 240V 100mA, Combined RCD/MCB Protection, Quick Trip

20A is the maximum continuous current the device should carry. 1P+N means it protects one live phase plus neutral in a single-phase system. 240V is the nominal operating voltage. 100mA leakage sensitivity means the RCBO will trip if leakage current reaches or exceeds 100 milliamperes.

Quick Trip indicates the device is designed to interrupt the circuit rapidly when a fault is detected, reducing the risk of damage from leakage, overload, or short-circuit conditions.

This RCBO is designed for DIN rail mounting in standard electrical distribution boards. It attaches to a DIN rail and occupies a single modular slot, saving panel space while providing reliable protection for the circuit it serves.

It is well suited for residential, small office, and light commercial circuits where leakage protection is important. It’s particularly useful in areas with sensitive electronics or where protecting a single circuit from both leakage and overcurrent is desired.

1) Switch off main power and verify no voltage. 2) Remove panel cover and prepare the DIN rail space. 3) Attach the RCBO to the DIN rail. 4) Connect the incoming live (L) and neutral (N) to the RCBO input terminals. 5) Connect the circuit’s load conductors to the RCBO output terminals. 6) Ensure all connections are secure and reassemble the panel. 7) Restore power and test the RCBO (use the built-in test function if present, or a certified RCBO tester to simulate fault conditions).

Have a qualified electrician perform installation, ensure the power is fully isolated before wiring, use proper PPE, verify correct wiring polarity, and follow local electrical codes. This device should be used with equipment and in panels rated for its specifications (20A, 240V, 1P+N, 100mA).

An RCD provides leakage protection only, while an MCB provides overload/short-circuit protection only. An RCBO combines both protections in one device, giving single-point protection for a circuit with controlled disconnection for both leakage and overcurrent events, and saving space in the distribution board.

It combines RCD and MCB protection in one compact unit, is designed for 20A circuits with 100mA leakage sensitivity, and offers quick-tripping protection in a single, space-saving device. These features can simplify wiring, reduce component count, and provide reliable protection for typical residential and small commercial circuits.
