PME-PEN Fault Detection Units

PME-PEN fault detection units provide essential PEN-loss protection for EV chargers installed on a TN-C-S (PME) supply. They automatically disconnect the charger if a PEN fault occurs, preventing dangerous touch voltages and removing the need for an earth rod.

Ideal for chargers without built-in PEN protection, these units offer a fast, compliant solution for domestic and commercial EV installations. Easy to fit, reliable, and fully aligned with BS 7671 requirements.

PME / PEN Fault Detection Consumer Units for EV Chargers

Ensure the safety, compliance, and efficiency of your EV charging systems with our range of PME / PEN Fault Detection Consumer Units. These units are specifically designed to address PME faults, PEN faults, and PEN loss, offering advanced protection for chargers that lack built-in fault detection and overload safeguards.

What Are PME / PEN Fault Detection Consumer Units?

PME / PEN Fault Detection Consumer Units actively monitor your electrical system for faults in Protective Multiple Earthing (PME) systems. These faults, including PEN faults and PEN loss, can compromise safety by electrifying the protective earth or creating dangerous voltage conditions. By detecting these issues and isolating Live, Neutral, and Earth conductors, these units safeguard users and connected devices.

What Are PEN Faults and PEN Loss?
  • PEN Fault: A partial failure in the Protective Earth and Neutral (PEN) conductor, which can result in unsafe voltage levels on the protective earth (PE).
  • PEN Loss: A complete disconnection of the PEN conductor, leading to significant safety risks, including electric shock and equipment damage.
  • PME Fault: A broader term encompassing faults within PME systems, including PEN faults and PEN loss, that compromise compliance and safety.

PEN loss and PEN faults are critical safety concerns that these units address effectively by isolating dangerous voltages and ensuring system compliance.

Key Features
  • PME Relays: Actively detect PME faults, PEN faults, and PEN loss, isolating the system to prevent hazardous conditions.
  • Type 2 Surge Protection Devices (SPD): Protect against voltage surges, extending the lifespan of your equipment.
  • Double Pole RCBOs: Disconnect both Live and Neutral conductors for comprehensive overcurrent and residual current protection.
  • Load Balancing: Ensures even power distribution across devices, preventing overload in properties with high-energy demands.
  • Kilowatt-Hour Meters: Real-time monitoring of energy consumption helps manage and reduce operational costs.
  • Weatherproof IP Enclosures: Ensure reliable operation in outdoor environments, protecting against dust and water.
Why Are These Units Essential for EV Chargers?

Electric vehicle chargers, particularly those without built-in PME fault detection, require additional safety measures to comply with regulations and protect users. PME / PEN Fault Detection Consumer Units:

  • Address critical safety issues caused by PEN faults and PEN loss.
  • Provide compliance with BS7671 wiring regulations.
  • Protect against surge damage with Type 2 SPDs.
  • Ensure optimal power distribution through load balancing.
Applications
  • Residential: Perfect for single-phase EV chargers like Tesla, ensuring safety by addressing PME faults, PEN faults, and PEN loss.
  • Commercial: Ideal for parking lots, offices, and retail spaces, offering fault detection and load balancing for multi-charger setups.
  • Industrial: Essential for facilities requiring robust fault detection and energy management for heavy-duty or fleet EV charging.
