32A C Curve Protection for Modern Installations
Rated at 32A, this WCED RCBO is designed to protect circuits where a C Curve tripping characteristic is appropriate. C Curve devices are commonly considered for circuits with moderate starting currents, such as certain equipment and machinery installations, subject to fault-loop impedance and disconnection requirements.
The combination of overcurrent and residual current protection within one device allows individual circuits to be protected independently, helping reduce unnecessary interruption to other circuits when a fault occurs.
Bi-Directional RCBO for Solar PV and EV Circuits
The WCED WRB132C-030 Bi-Directional RCBO belongs to the WRB1 range, which the manufacturer identifies as designed for bi-directional use in PV and EV systems.
Its design enables use in appropriately specified circuits where the direction of power flow may vary. This can be relevant to solar photovoltaic generation and certain EV charging arrangements, provided the connected equipment and installation requirements are compatible.
Installation must follow the manufacturer’s connection instructions and terminal markings. The product datasheet specifies a bottom connection arrangement.
Type A High-Immunity Residual Current Protection
The WRB132C-030 provides Type A residual current protection, detecting sinusoidal AC and pulsating DC residual fault currents. This offers broader residual current detection than Type AC devices and supports its use with a range of modern electrical equipment.
Its 30mA sensitivity provides additional protection against electric shock when correctly installed. The high-immunity classification forms part of the manufacturer’s WRB1 product specification.
Switched Live and Neutral for Easier Circuit Isolation
The 1P+N design incorporates switched live and neutral conductors, allowing both conductors of the protected circuit to be disconnected when the device operates.
This arrangement supports circuit isolation and can help simplify certain inspection and insulation resistance testing procedures, reducing unnecessary disconnection work where the test method permits.
Single-Module Design and Bi-Connect Terminals
The compact RCBO occupies approximately 18mm of DIN rail space, allowing efficient installation in compatible consumer units and distribution boards.
Its bi-connect terminal system supports suitable cable, pin-type and fork/U-type busbar connections. The manufacturer specifies a 2.5Nm tightening torque and installation on a standard 35mm DIN rail.
