WCED WRB132B-030 Bi-Directional RCBO
The WCED WRB132B-030 Bi-Directional RCBO is a 32A B Curve protective device from the Whitecliffe Electrical WRB1 range. Combining overload, short-circuit and residual current protection within a single-module housing, it features 30mA Type A high-immunity detection and a 6kA rated breaking capacity.
Designed for suitably rated domestic and commercial circuits, the WRB132B-030 also provides bi-directional capability for compatible solar photovoltaic installations. Its switched live and neutral configuration allows both conductors to be disconnected when the device operates, offering practical benefits during inspection, testing and circuit isolation.

32A B Curve Protection for Domestic and Commercial Circuits
The WRB132B-030 combines a 32A current rating with a B Curve tripping characteristic, making it an option for appropriately designed circuits with relatively low inrush currents.
Its integrated residual current and overcurrent protection helps protect individual circuits independently. This can reduce disruption to other circuits when a fault occurs, compared with arrangements where multiple circuits share one residual current protective device.
Bi-Directional Design for Solar PV Applications
The WCED WRB132B-030 Bi-Directional RCBO forms part of the WRB1 range designed for bi-directional operation. This enables the device to be considered for correctly designed photovoltaic systems where electrical power may flow in different directions.
For solar installations, device suitability must be established with reference to the inverter characteristics, circuit rating and relevant protective requirements.
The manufacturer’s terminal markings and installation instructions must be followed. The WCED datasheet specifies connection from the bottom.
Type A High-Immunity Residual Current Protection
Type A protection detects sinusoidal AC and pulsating DC residual fault currents, offering a wider range of residual current detection than traditional Type AC devices.
The WRB132B-030 provides 30mA sensitivity for additional protection against electric shock when correctly installed. Its high-immunity classification is part of the manufacturer’s WRB1 specification.
Switched Live and Neutral for Circuit Isolation
The RCBO incorporates a 1P+N arrangement with switched live and neutral as standard. Both conductors are disconnected during operation, supporting the isolation of individual circuits for inspection and maintenance.
This configuration may also simplify certain insulation resistance testing procedures, subject to the testing method and connected equipment.
Single-Module Construction and Bi-Connect Terminals
With an approximately 18mm module width, the WRB132B-030 helps conserve space in compatible consumer units and distribution boards.
Its bi-connect terminals accept compatible cable, pin-type and fork/U-type busbar connections. The manufacturer specifies a 2.5Nm terminal tightening torque and mounting onto a standard EN 60715 35mm DIN rail.
