Description
Whitecliffe WHP Type B HP 40A High-Performance RCD
Type B HP 40A RCD for Heat Pump & Inverter-Drive Protection
The ️Type B HP 40A RCD for Heat Pumps is engineered for modern heat pumps and inverter-driven systems. It detects smooth DC faults at any level and operates reliably at high frequencies, helping you stay aligned with BS 7671 requirements in demanding applications.
Installers choose this 40A heat pump RCD for nuisance-free protection on variable-speed compressors and drives. Its two-module, two-pole design saves space and fits a standard busbar, speeding up installs while maintaining robust residual current protection.
For projects where high-frequency residual currents are present, the WHP Type B HP 40A offers verified tripping performance above 20 kHz with a defined threshold above 1 kHz—ideal for today’s low-carbon heating systems.
