PME / PEN Fault Detection Unit with Load Management and Kilowatt Hour Meter
WCED WPEPME12/LB
The WPEPME12/LB is a weatherproof, IP65-rated PME / PEN Fault Detection Unit designed for EV charging systems requiring advanced safety and compliance. This 12-module unit combines PME fault detection, load management, and a built-in kilowatt-hour meter to deliver comprehensive protection for chargers that lack integral PME protection, earth leakage protection, or overload protection. It is ideal for installations in residential, commercial, and mixed-use properties with high-energy demands.
Key Features of IP65 PME / PEN Fault Detection Unit WPEPME12/LB
- PME / PEN Fault Detection: Monitors and isolates faults related to PME faults, PEN faults, or PEN loss, ensuring safety and compliance.
- Load Management: Utilises a current transformer on the main incoming supply to distribute power efficiently, preventing overloads.
- Kilowatt-Hour Meter: Built-in meter provides real-time monitoring of energy usage, helping users track consumption.
- Automatic Voltage Monitoring:
- Under-Voltage Protection: Isolates supply if voltage drops below 207V and automatically resets when normal voltage is restored.
- Over-Voltage Protection: Isolates supply if voltage exceeds 253V, requiring a manual reset via the RED “RESET” button for safety.
- Integrated Protection: Includes a C40 RCBO, relays, and a Type 2 Surge Protection Device (SPD) for comprehensive coverage.
- Weatherproof Design: IP65-rated enclosure ensures reliable operation in outdoor environments.
- Compact 12-Module Design: Space-efficient with dimensions suitable for various installations.

Load Management Explained
Load management ensures that the available power capacity is distributed efficiently across all connected devices, preventing overloading of the electrical system. The WPEPME12/LB achieves this by using a current transformer to monitor the main incoming supply. This feature is especially useful in properties with high-energy appliances like induction hobs, electric showers, and heating systems, alongside EV chargers.
Understanding PME Faults, PEN Faults, and PEN Loss
PME faults, PEN faults, and PEN loss are safety-critical conditions caused by failures in PME systems:
- PEN Fault: Partial failure of the PEN conductor, leading to unsafe voltage levels on the protective earth conductor (PE).
- PEN Loss: Complete disconnection of the PEN conductor, creating a risk of electric shock and damage to connected devices.
- PME Fault: A general term for faults within PME systems that can result in non-compliance and hazardous conditions.
The WPEPME12/LB actively detects and isolates these faults, ensuring the safety of users, EV chargers, and connected systems.
Applications
- Residential: Perfect for single-phase EV chargers like Tesla, providing safety by addressing PME faults and PEN loss.
- Commercial: Suitable for outdoor EV charging setups in retail spaces, parking lots, and office environments.
- Mixed-Use Properties: Ideal for setups requiring PME fault detection, load management, and energy monitoring.
Why This Unit is Essential
The WPEPME12/LB is a critical component for ensuring safe and compliant EV charging installations. Its combination of PME fault detection, load management, and kilowatt-hour metering makes it an essential solution for modern electrical systems.
