Description
PME / PEN Fault Detection Unit with Load Management
WCED WMEPME10/LB
The WMEPME10/LB is a high-quality PME / PEN Fault Detection Unit with integrated load management functionality. Designed for EV chargers without built-in PME protection, earth leakage protection, or overload protection, this unit ensures compliance and safety in modern charging systems. It actively monitors the supply voltage and isolates Live, Neutral, and Earth in the event of under-voltage or over-voltage conditions.
Additionally, its load management feature prevents overcapacity by distributing power efficiently.
Key Features of PME / PEN Fault Detection Unit WMEPME10/LB
- PME / PEN Fault Detection: Actively isolates all phases and earth upon detecting PME faults, PEN faults, or PEN loss.
- Voltage Monitoring: Automatically monitors the supply voltage on 230V and 240V systems.
- Under-Voltage Protection: Isolates supply if voltage drops below 207V, automatically resets when normal voltage is restored.
- Over-Voltage Protection: Isolates supply if voltage exceeds 253V, requires manual reset via the RED “RESET” button on the WVP32 for added safety.
- Load Management: Uses a current transformer to monitor the incoming supply, preventing overloads by distributing capacity efficiently.
- Integrated Protection: Includes a C40 RCBO, relays, and a Type 2 Surge Protection Device (SPD) for comprehensive safety.
- Compact Design: 10-module unit with dimensions that fit easily into standard electrical panels.
- Durable Build: IP-rated enclosure ensures long-lasting performance in various environments.

Load Management Explained
Load management is essential for properties with high-current appliances like induction hobs, electric showers, or heating systems. The WMEPME10/LB uses a current transformer on the main incoming cable to monitor load levels and prevent overcapacity. By distributing power efficiently across all connected devices, it ensures that EV chargers operate reliably without overloading the electrical system.
Applications
- Residential: Ideal for single-phase EV chargers, such as Tesla, installed in homes with high-energy appliances.
- Commercial: Provides safety and efficiency for EV charging points in retail spaces, offices, or parking lots.
- Mixed-Use Properties: Suitable for setups requiring PME fault detection, load management, and surge protection.
Understanding PME Faults, PEN Faults, and PEN Loss
PME faults, PEN faults, and PEN loss all describe the same issue: a failure in the PEN conductor within PME systems.
- PEN Fault: Partial failure of the PEN conductor, potentially electrifying the protective earth conductor (PE).
- PEN Loss: Complete disconnection of the PEN conductor, creating hazardous conditions for EV chargers and other connected systems.
- PME Fault: General term for faults in PME systems leading to unsafe voltage conditions.
The WMEPME10/LB actively detects and isolates these faults, preventing risks such as electric shocks or equipment damage.
Why This Unit is Essential
The WMEPME10/LB ensures the safety and reliability of EV charging systems by combining PME fault detection, voltage monitoring, surge protection, and load management in one compact unit. Its ability to address PME faults, PEN faults, and PEN loss makes it indispensable for compliant installations. The load management feature enhances efficiency, making it ideal for properties with high-current demands.
