Hager B-HP
The device designed specifically for Heat Pumps, overcoming the limitations of Standard Type B RCCBs, functioning at frequencies greater than 20 kHz.

- Overcomes the limitations of standard Type B devices
- Eliminates nuisance tripping at frequencies above 1kHz
- Critical protection against all residual current types
- Ensures safety and reliability for the homeowner
Why Type B HP RCDs Are Essential for Heat Pumps.
Heat pumps, particularly those with inverter-driven compressors, generate high-frequency currents during AC-DC switching. These currents often include DC components and high-frequency residual currents that exceed the capabilities of standard 50 Hz Type B RCDs.
Some installers mistakenly believe that Type B+ devices are suitable for heat pump applications. However, Type B+ is a VDE standard and is not recognised by BS 7671.

""As the push for renewable energy accelerates, ensuring the safety and reliability of electrical systems is paramount. The widespread adoption of air source heat pumps plays a critical role in reducing carbon emissions and achieving net-zero targets, but these advanced systems introduce unique electrical challenges. Hager’s Type B HP RCCB is specifically engineered to support this transition by offering superior protection against high-frequency leakage currents that standard RCCBs cannot handle."
