WMRC32CSP is a 4 way metal EV protection unit supplied with a 32A C Curve A-Type RCBO and built-in surge protection. Designed for EV charger circuits with higher inrush characteristics, it provides overload, earth leakage, and surge protection in one compact pre-configured enclosure.
Installer Tip: The dual switch action indicates the type of fault detected, helping electricians identify whether the trip relates to overcurrent or earth leakage during commissioning and fault finding.
- 4 way metal enclosure – compact pre-built EV protection format
- 32A C Curve A-Type RCBO – suited to EV circuits with higher startup or inrush characteristics
- High immunity design – helps reduce nuisance tripping
- 30mA AC earth leakage protection
- 6mA DC earth leakage detection
- Built-in surge protection – helps protect connected equipment from transient overvoltages
- Pre-wired assembly – built for faster installation
- Dimensions: 110mm x 175mm x 91mm
This version is well suited to EV charger circuits where a 32A C Curve A-Type RCBO is preferred over a B Curve device. You can also browse related products in our EV protection range, RCBO collection, and surge protection range.
| Model | RCBO Rating | Curve Type | SPD Type | Ingress Rating | Common Use |
|---|---|---|---|---|---|
| WMRC32BSP | 32 A | B Curve | Type 2 | IP40 (Metal) | Standard domestic EV charger ≤7.4 kW |
| WMRC32CSP | 32 A | C Curve | Type 2 | IP40 (Metal) | Commercial EV charger or higher inrush load |
| WMRC40BSP | 40 A | B Curve | Type 2 | IP40 (Metal) | High-load EV charger ≤9.6 kW |
| WMRC40CSP | 40 A | C Curve | Type 2 | IP40 (Metal) | Heavier-duty or inverter-driven systems |
This 32 A C-Curve model is ideal for commercial or mixed-load EV charger setups where transient inrush currents are common. Fully compliant with BS 7671 and factory-tested for rapid installation and inspection approval.
When should I choose a C Curve RCBO?
A C Curve RCBO is typically used where the circuit has higher startup or inrush characteristics than a standard B Curve application.
What protection does WMRC32CSP provide?
WMRC32CSP combines overload protection, 30mA AC earth leakage protection, 6mA DC earth leakage detection, and built-in surge protection in one enclosure.
What does the dual switch action indicate?
The dual switch action indicates the type of fault detected, helping installers distinguish between overcurrent and earth leakage trips.
Can this be used on EV charger circuits?
Yes. This version is designed for EV charger circuits where a 32A C Curve A-Type RCBO is the preferred protective format.
Are other versions available?
Yes. Related models are available in 32A and 40A ratings, including both B Curve and C Curve versions within the same product family.
