Standalone Type B RCD
Choose a separate device when the panel design calls for an individual RCD rather than a fitted assembly.
View options & prices →Before you choose
1
Start with the equipment manual
Record the heat-pump model, supply phase, circuit rating and the required RCD characteristics. Do not assume every heat pump needs the same device.
2
Choose the assembly
Compare a fitted consumer unit with an individual RCD. Check the exact MCB, SPD and enclosure supplied in the selected option.
3
Confirm the installation
Check coordination with upstream protection, cable design, mounting environment and the manufacturer's installation instructions.
Planning an enclosure and components?
Our consumer-unit builder lets you choose single-phase or three-phase, select an enclosure and track the spare DIN space as you add supported components. Custom selections are supplied separately; factory-configured units have their own stated contents.
Build your own consumer unit →Frequently asked questions
Does every heat pump need a Type B RCD?
No universal selection applies to every model. Follow the equipment manufacturer's specified residual-current protection and the installation design.
Is a Type B RCD the same as a B-curve MCB?
No. Type B describes residual-current detection characteristics. B curve describes an MCB's instantaneous overcurrent trip characteristic.
Does an RCD also protect against overload?
An RCD alone does not provide overload or short-circuit protection. A suitable overcurrent protective device is also needed as part of the design.
Can I order protection without a complete consumer unit?
Yes. The standalone Type B RCD range is linked here. Check that the chosen device is compatible with the intended assembly.
