WCED WRB116B-030 Bi-Directional RCBO
The WCED WRB116B-030 Bi-Directional RCBO is a 16A B Curve protective device from the Whitecliffe Electrical WRB1 range. Designed for installations requiring both overcurrent and residual current protection, it combines a 30mA Type A high-immunity RCD function with a 6kA short-circuit breaking capacity in one compact module.
This model provides a practical solution for appropriately designed lighting, fixed electrical equipment and other 16A circuits where a B Curve trip characteristic is suitable. Its bi-directional capability also allows it to be considered for compatible solar photovoltaic installations.

16A B Curve Protection for Lighting and Fixed Loads
The WRB116B-030 provides 16A overcurrent protection with a B Curve tripping characteristic, generally selected for circuits with relatively low starting currents. Potential applications include suitable lighting installations, fixed equipment supplies and other correctly rated final circuits.
By providing both residual current and overcurrent protection in one device, the RCBO allows individual circuits to be protected separately. This helps limit disruption to unaffected circuits when a fault occurs.
Bi-Directional Operation for Solar PV Circuits
The WCED WRB116B-030 Bi-Directional RCBO belongs to the manufacturer’s WRB1 range, designed for applications where electrical power may flow in either direction.
For appropriately designed solar photovoltaic circuits, bi-directional operation is an important consideration when selecting protective devices. Compatibility must be checked against the inverter specifications, circuit configuration and applicable protection requirements.
Installers must follow the manufacturer’s terminal markings and wiring instructions. The WCED datasheet specifies a bottom connection arrangement.
Type A High-Immunity Residual Current Protection
The WRB116B-030 responds to sinusoidal AC and pulsating DC residual fault currents, providing Type A protection for compatible modern electrical equipment.
Its 30mA residual current sensitivity delivers additional protection against electric shock when correctly installed. The high-immunity classification forms part of the WRB1 range specification.
Switched Live and Neutral
The 1P+N arrangement incorporates switched live and neutral as standard. When the protective device operates, both conductors are disconnected, supporting individual circuit isolation for inspection and maintenance.
This configuration can simplify certain insulation resistance testing procedures, depending on the test method and connected equipment.
Compact Design with Bi-Connect Terminals
Occupying approximately 18mm of DIN rail space, the WRB116B-030 is designed for compatible consumer units and distribution boards where efficient use of space is important.
Its bi-connect terminals support compatible cable, pin-type and fork/U-type busbar connections, with a manufacturer-specified tightening torque of 2.5Nm.
