Description
The WHP240-030 is a 40A Type B HP RCD for inverter-driven heat pumps, providing smooth DC residual-current protection in a compact two-module format where the heat-pump specification calls for it.
Heat-pump protection in a compact format
Inverter-driven equipment can produce smooth DC and high-frequency residual currents. Whitecliffe developed the WHP range for these conditions, with testing above 20kHz. It gives installers a dedicated heat-pump RCD option when planning a compatible protection assembly.
- Type B HP detection: covers smooth DC residual currents as well as the AC and pulsating DC waveforms associated with Type A protection.
- Two-pole, two-module design: helps you plan enclosure space around the RCD and the other required devices.
- 40A rated current and 30mA rated sensitivity: the key figures for matching the device to the project specification.
- Manufacturer documentation available: review the high-frequency characteristics in the Technical Specs tab and Whitecliffe Type B HP RCD datasheet (PDF).
Specifying the RCD? Match the residual-current requirements to the exact heat-pump model. This device provides residual-current protection; coordinated overload and short-circuit protection must also form part of the installation.
Separate RCD, combined RCBO or complete board?
Choose the format that fits the job. These options have different functions and are not interchangeable solely because they share a 40A rating.
| Product | Configuration | When to consider it |
|---|---|---|
| WHP240-030 — this product | 40A, 30mA Type B HP RCD; two modules | You need a separate heat-pump RCD in a compatible assembly with coordinated overcurrent protection. |
| WHR140B-030 heat-pump RCBO | 40A B curve, 30mA Type B HP RCBO; one module | You need residual-current and overcurrent protection combined, and the circuit specification calls for this rating and curve. |
| WME08/HP40C heat-pump board | Metal enclosure with heat-pump RCD, MCB and surge protection | You are specifying a dedicated heat-pump board. Review the fitted components and availability on its product page. |
For other configurations, browse heat-pump consumer units or the Type B RCD range.

Installation notes
Installation and testing must be carried out by a qualified electrician using the instructions supplied with the exact RCD and heat pump, together with the applicable BS 7671 requirements.
- Confirm the required RCD type and residual-current characteristics for the heat-pump model.
- Check enclosure and busbar compatibility, connection markings and coordinated overcurrent protection.
- Use test equipment and procedures suitable for the device and follow the manufacturer's commissioning requirements.
FAQs
When should I specify WHP240-030?
When the heat-pump manufacturer and installation design call for a 40A, 30mA Type B HP RCD. The range is designed for smooth DC and high-frequency residual currents associated with inverter-driven equipment; requirements still depend on the exact heat-pump model.
Does it include overload and short-circuit protection?
No. WHP240-030 is an RCD and needs coordinated overcurrent protection. If your design calls for a combined device, compare the WHR140B-030 heat-pump RCBO.
How much space does it need?
The device occupies two modules. Check the enclosure and busbar compatibility as well as physical clearance before ordering; contact Power & Data UK for confirmation of exact mounting dimensions.
What does the 150mA figure mean?
Whitecliffe states a minimum tripping threshold of 150mA for frequencies above 1kHz. This is a frequency-specific characteristic, separate from the nominal 30mA residual-current rating, and is not an upper limit for smooth DC detection.
Can I order a complete heat-pump board instead?
Yes. Compare the WME08/HP40C heat-pump consumer unit or browse heat-pump boards. Check the fitted devices and current availability against your project requirements.
