Description
30mA RCCB 1P+N Type B HP 25A for Heat Pumps
Hager CDB525HP
Heat pumps are popular for energy-efficient heating, but they bring unique electrical challenges. They generate high-frequency residual currents and DC leakage, which can cause nuisance tripping or leave faults undetected.
The Hager CDB525HP is a 25A Type B HP RCCB built to solve these problems. It operates at frequencies up to 20 kHz, preventing false tripping and RCCB blinding. Designed for small to mid-sized heat pump systems, it ensures stable operation and continuous protection.
This device meets BS 7671 regulations, making it a reliable choice for installers and homeowners.
