Live Electrical LHP840MSE Heat Pump Consumer Unit
The live electrical LHP840MSE heat pump consumer unit is a compact and purpose-built solution for modern installations requiring reliable protection for heat pumps and inverter-driven systems. Housed in an 8 module metal enclosure, this unit combines advanced safety devices with a space-saving design ideal for residential and light commercial applications.
Equipped with a 40A Type B HP RCD, a 40A C curve double pole MCB, a 100A main switch and a Type 2 surge protection device (SPD), this consumer unit delivers comprehensive protection against electrical faults, surges and high-frequency leakage currents.
Advanced Heat Pump Protection
The included Live CEB240-030 40A Type B HP RCD is specifically engineered for installations where DC components and high-frequency leakage currents are present. Operating beyond 20kHz with a raised 150mA trip threshold above 1kHz, it helps reduce nuisance tripping while maintaining accurate fault detection.
This makes the unit ideal for heat pumps, EV chargers and inverter-based systems where standard RCDs may not provide sufficient protection.
