Description
30mA RCCB 1P+N Type B HP 40A for Heat Pumps
Hager CDB540HP
Heat pumps with inverter-driven compressors create high-frequency currents that can overload standard RCCBs. This often leads to nuisance tripping or, worse, undetected faults.
The Hager CDB540HP is a 40A Type B HP RCCB, built for medium-sized heat pump systems. It prevents false tripping, RCCB blinding, and DC fault issues. With an operating frequency up to 20 kHz, it ensures stable performance and uninterrupted protection. It complies with BS 7671 regulations, making it a safe and future-proof solution.
