The WRT132B-030 is a 32A B Curve Type A RCBO that delivers overcurrent and 30mA residual current protection in one slimline device. It features switched live and neutral isolation for safe disconnection, a high immunity design to reduce nuisance trips, and bi-directional wiring that makes it suitable for solar PV, EV charging, and inverter-based circuits.
Built to IEC/EN 61009-1 standards, this RCBO is fully compliant with the 18th Edition Wiring Regulations (Amendment 2) and can be installed in standard 18mm DIN rail consumer units for domestic and commercial projects.
Installer Tip: Use the B Curve for domestic socket and lighting circuits where inrush currents are low. For EV chargers, motors, or heat pumps, select the C Curve version instead.

When should I use a 32A RCBO?
It’s ideal for higher rated domestic and light commercial circuits where 32A overload protection is required alongside residual current safety.
What makes a Type A RCBO different?
Type A RCBOs detect pulsating DC leakage as well as AC faults, essential for modern appliances, EV chargers, and solar inverters.
Does it fully isolate the circuit?
Yes – switched live and neutral poles ensure both conductors are disconnected on trip.
Why high immunity?
It helps resist nuisance tripping from harmonics and surges, common in inverter-heavy systems.
