WARB5100C/PME 3 Phase PME Fault Detection Unit – Essential Safety with MCB and PME Relay
Secure Protection with PME Fault Detection and MCB for 3 Phase EV Charging Systems
The WARB5100C/PME is a high-performance 3 phase EV distribution board designed to enhance safety and ensure compliance in electric vehicle (EV) charging installations. When a PME (Protective Multiple Earthing) fault occurs, this unit disconnects all phases and the earth, providing a safer charging environment without requiring an earth rod.
This model, WARD5100C/PME, features a 100A Curve C MCB and a PME relay. These components deliver essential overcurrent protection and reliable PME fault detection, making it an ideal choice for EV chargers that require robust safety measures.
Key Features:
- Automatic Monitoring: The unit continuously monitors the 400V supply voltage across all phases, ensuring consistent operation and immediate response to anomalies.
- 100A Curve C MCB: Protects your EV charging system by offering reliable overcurrent protection, reducing the risk of damage.
- PME Relay: Disconnects all phases and earth automatically when it detects a PME fault, ensuring compliance with safety standards.
- PME Fault Detection: Actively isolates the system upon detecting a PME fault, thus protecting both the installation and the vehicle.
- Auto Reset for Under-Voltage: Automatically resets after under-voltage isolation when normal voltage levels are restored, ensuring minimal downtime.
- Manual Reset for Over-Voltage: Requires a manual reset via the RED “RESET” button after over-voltage isolation to maintain safety.
Safety Warning:
Qualified electricians must install this product according to IET wiring regulations BS7671 and current building regulations. Always disconnect the electrical supply before installation or removing the cover. After installation, the unit contains a live main supply (400V or higher), so you should never remove the cover until the supply is isolated or disconnected.
