The WER32B/Solus is a 32A B Curve Type A RCBO with integrated Surge Protection, supplied as a ready-to-fit Solus Pack. It provides full 30mA residual current protection with overload and short-circuit defence, while the built-in Type 2 SPD ensures compliance with the 18th Edition Wiring Regulations (Amendment 2) for EV chargers, solar PV, and inverter-based systems.
Pre-assembled for speed on site, the high immunity design resists nuisance tripping from harmonics and transients, making it suitable for domestic, commercial, EV, and solar installs.
Installer Tip: Choose the B Curve for domestic lighting and standard load circuits. For EV charge points, motors, and high inrush equipment, select the C Curve variant.
Key Features
- 32A B Curve Type A RCBO – 30mA sensitivity, 10kA rated
- High immunity – resists nuisance tripping from transients
- Integrated Type 2 SPD – 18th Edition Amendment 2 compliant
- Double pole disconnection – cuts both live and neutral
- Bi-directional wiring – line/load reversible for solar & battery systems
- DIN rail mounted – fast fit in consumer units and EV boards

When should I choose a B curve RCBO?
B curves suit low inrush loads such as lighting or domestic circuits. For EV charge points, motors, or heat pumps, the C curve variant is usually recommended.
Does this include surge protection?
Yes – the Solus pack integrates a Type 2 SPD, meaning no separate surge module is required for compliance.
Can this be used on EV charger circuits?
Yes, provided the charger manufacturer specifies Type A RCBO protection. For PME systems, pair with a PME Fault Detection Unit.
Is this bi-directional?
Yes – line and load can be reversed, making it compatible with inverter-fed circuits such as solar PV.
