The WARB5100C/PME63DRSP is the flagship 3 Phase PME Fault Detection Unit. It integrates a 100A MCB main switch, PME relay, a 63A Type A RCBO, and a Type 2 SPD. Built for high-demand EV charging hubs, solar PV systems, and industrial 3-phase supplies, it provides the broadest compliance and protection in the range.
The PME relay continuously monitors all three phases at 400/415V. If undervoltage (below 207V) occurs, the board disconnects and auto-resets once stable. If overvoltage (above 253V) occurs, it isolates and requires a manual reset via the red button. This ensures safe, controlled recovery and compliance with BS7671:2018+A2:2022.
Installer Tip: Choose the 63DRSP model for large commercial EV charger banks or heavy 3-phase renewables where a 40A RCBO isn’t sufficient. It’s the maximum protection available in this series.
Key Features
- PME Fault Detection: Isolates all poles & earth on PEN loss
- 63A Type A RCBO: Handles higher loads with overload + leakage protection
- Type 2 SPD: Suppresses transient surges with visual indicator
- 100A MCB Main Switch: Provides upstream protection and isolation
- Auto Monitoring: Continuous undervoltage & overvoltage detection
- Reset Modes: Auto reset (undervoltage), manual reset (overvoltage)
- Applications: High-load EV charging sites, solar farms, industrial 3-phase systems
