RCBO
WRCA Type A/AC Standard RCBO
Overload, short-circuit and earth-fault protection for one final circuit in a single module. The handle takes a padlock, so a circuit can be locked off for work without pulling the device.

RCBO Protection
Combined residual-current and overcurrent protection for individual final circuits, in single-module, switched-neutral, electromagnetic, three-phase, Type B and arc-fault-detecting versions.

RCBO
WRCM Electromagnetic RCBO
An electromagnetic tripping system rather than an electronic one, so operation does not depend on the supply voltage being present. Available on C and D characteristics at 10kA.

RCBO
WRCN Mini RCBO — Switched Neutral
MCB-sized RCBO with switched neutral as standard. Isolating the neutral with the line means only the faulty circuit is taken out of service, which shortens installation and periodic testing.

RCBO
WAFD Arc Fault Detection Device with RCBO
Arc fault detection on top of a full RCBO: overload, short circuit and residual current in the usual single module, plus the series arcing that none of those three responds to — the fault behind a damaged cable or a loose terminal.

RCBO
WRCB Type B Mini RCBO
Type B residual-current detection and overcurrent protection in one single-module body, for circuits where smooth DC residual current can occur — EV charge points and PV-connected installations — and board width is still limited.

RCBO
WRCF Three-Phase Electromagnetic RCBO
The three-phase member of the RCBO range: 3P+N, up to 63A and 10kA, with an electromagnetic residual-current mechanism that does not depend on the supply voltage to trip.

RCBO
WRCW Mini Electromagnetic RCBO
A 1P+N electromagnetic RCBO up to 40A on a 6kA capacity — the same voltage-independent tripping as the WRCM, in the smaller frame and lower breaking capacity that residential boards normally call for.

RCBO
WRCT Double Pole RCBO (Twin Switches)
Two switches on one double-module body, so the residual-current and overcurrent halves can be operated separately — useful when a fault has to be isolated without dropping the whole circuit.
