WCED WRB116C-030 Bi-Directional RCBO
The WCED WRB116C-030 Bi-Directional RCBO is a 16A C Curve circuit protection device from the Whitecliffe Electrical WRB1 range. Combining residual current protection with overload and short-circuit protection, this single-module Type A high-immunity RCBO provides 30mA residual operating sensitivity and a 6kA breaking capacity for domestic and commercial electrical installations.
Designed for bi-directional operation, the WRB116C-030 can also be considered for appropriately designed solar PV circuits where the direction of current flow may vary. Its switched live and neutral configuration supports individual circuit isolation within compatible consumer units and distribution boards.

16A C Curve Overcurrent Protection
The 16A C Curve characteristic makes the WRB116C-030 suitable for appropriately designed circuits where moderate inrush currents may occur. Circuit selection must account for cable ratings, prospective fault current, earth fault loop impedance and required disconnection times.
Combining overcurrent and earth leakage protection in a single device helps provide independent protection for individual final circuits, reducing the likelihood of faults interrupting unrelated circuits.
Bi-Directional Design for Solar PV Installations
The WCED WRB116C-030 Bi-Directional RCBO is designed to accommodate bi-directional power flow in suitably configured electrical installations. This characteristic can be particularly relevant to solar photovoltaic systems where generation and consumption may affect the direction of power flow.
The manufacturer specifies a bottom connection arrangement, and all terminal markings and installation instructions must be followed. Compatibility with the selected inverter, distribution equipment and protective arrangements should be confirmed before installation.
Type A High-Immunity Residual Current Protection
Type A residual current detection enables the RCBO to respond to both sinusoidal AC and pulsating DC residual fault currents. Compared with Type AC devices, it provides a broader range of residual current detection for modern electrical equipment.
The 30mA sensitivity offers additional protection against electric shock when correctly installed. The high-immunity classification is part of the WRB1 range specification, providing a solution for installations where operational continuity is an important consideration.
Switched Live and Neutral
The WRB116C-030 incorporates switched live and neutral as standard. Both conductors are disconnected when the protective device operates, helping with individual circuit isolation and inspection.
This arrangement can also simplify certain insulation resistance testing procedures without needing to disconnect both conductors manually, subject to the testing method and connected equipment.
Single-Module Installation and Bi-Connect Terminals
The compact single-module enclosure occupies approximately 18mm of DIN rail space, making it suitable for compatible consumer units where available installation space is limited.
Bi-connect terminals support compatible cable, pin-type and fork/U-type busbar connections. The manufacturer’s specified terminal tightening torque is 2.5Nm, with mounting on a standard EN 60715 35mm DIN rail.
