Description
The WRT332C-030 is a 3-pole Type A RCBO designed to provide combined residual current and overcurrent protection for three-phase installations. Rated at 32A with a C curve tripping characteristic and 30mA sensitivity, it protects circuits against overload, short-circuit, and earth leakage faults in a compact 3-module format.
Type A protection enables detection of AC residual currents and pulsating DC components, making this RCBO suitable for modern electrical systems with electronic or inverter-based loads. The C curve response allows it to accommodate moderate inrush currents, commonly found in motors, commercial equipment, and mixed-load distribution boards.
Installer note: Switched neutral operation ensures L1, L2, L3, and N are disconnected together, improving safety and simplifying insulation resistance testing.

| Part Code | Rating | Curve | Residual Current |
|---|---|---|---|
| WRT332C-030 | 32A | C Curve | 30mA |
| WRT320C-030 | 20A | C Curve | 30mA |
| WRT332B-030 | 32A | B Curve | 30mA |
| WRT340B-030 | 40A | B Curve | 30mA |
| WRT340C-030 | 40A | C Curve | 30mA |
| WRT350C-030 | 50A | C Curve | 30mA |
The WRT332C-030 is suited to three-phase circuits where Type A protection and tolerance for moderate inrush currents are required without compromising residual current safety.

FAQs
What is the difference between B curve and C curve RCBOs?
C curve RCBOs allow higher inrush currents than B curve devices, making them suitable for motor-driven or mixed-load circuits.
Does this RCBO include a switched neutral?
Yes. The neutral is switched, providing full disconnection of all live conductors.
Is this suitable for three-phase commercial installations?
Yes. It is designed for three-phase commercial, industrial, and advanced residential circuits where Type A protection is required.
What is the breaking capacity of this RCBO?
The WRT332C-030 has a rated short-circuit breaking capacity of 10kA.
Is this device supplied pre-wired?
No. It is supplied as a DIN-rail-mounted RCBO and must be wired during installation.
