Product Information
Full details
The WCED WMEPME06/C40 PME loss unit is designed for installations requiring enhanced electrical protection, particularly for Electric Vehicle (EV) chargers that lack integrated PME protection, earth leakage, overload, and load management features. Its primary benefit is automatic voltage monitoring and isolation, safeguarding connected equipment from damaging voltage fluctuations. A key consideration is its specific reset mechanism following over-voltage events, requiring manual intervention.

FAQs
What is PME protection and why is it important for EV chargers?
PME (Protective Multiple Earthed) protection is a safety feature in electrical installations. Some EV chargers require specific PME fault detection and protection, which this unit provides if the charger itself lacks it, preventing potential electric shock hazards.
What is the voltage range for normal operation?
The unit operates normally between 207V and 253V AC.
How quickly does the unit isolate power during voltage fluctuations?
It isolates the Live, Neutral, and Earth connections within 4 seconds of detecting an under-voltage (below 207V) or over-voltage (above 253V) condition.
Does the unit automatically reset after an over-voltage event?
No, following an over-voltage isolation, the unit requires a manual reset by pressing the "RED" button. This is a safety feature.
What does the 'Type A RCBO' designation mean?
Type A indicates the RCBO can detect both sinusoidal AC residual currents and pulsating DC residual currents. This offers broader protection against various fault types.
Can this unit be used for general household circuits, or only EV chargers?
While designed with EV chargers in mind (especially those needing PME loss protection), it can be used on any 40A circuit requiring voltage monitoring and RCBO protection, provided it meets the installation requirements.
What is the short circuit rating of this unit?
The WCED WMEPME06/C40 has a rated conditional short circuit current of 16kA.
Troubleshooting
Unit trips immediately upon connection
This could indicate a fault in the connected EV charger or wiring. Check for short circuits or incorrect wiring. Ensure the main device (RCBO) is correctly rated for the circuit.
Unit does not reset after an over-voltage event
This is by design for safety. Ensure the over-voltage condition has been resolved, then manually press the "RED" reset button firmly.
No power to the EV charger
Verify the main power supply is active. Check if an under-voltage or over-voltage isolation has occurred by observing the unit's status. If isolated due to under-voltage, wait for the supply to normalize; if over-voltage, press the red reset button after confirming stable supply.
Unit trips during normal EV charging operation
This may indicate an overload or earth leakage issue. Check the EV charger's current draw against the unit's 40A rating. If the issue persists, consult an electrician to diagnose potential earth faults or RCBO malfunction.
Pros and Cons
Pros
- Enhances safety for EV chargers lacking built-in PME protection.
- Protects against damaging under-voltage and over-voltage conditions.
- Automated under-voltage reset simplifies operation.
- Clear indication and manual reset for over-voltage events ensure user awareness.
- Compact and integrated solution with RCBO functionality.
Cons
- Requires manual reset after over-voltage incidents.
- Specific to applications needing PME loss protection for EV chargers.
- Installation requires qualified electrical knowledge.
Setup, Compatibility & Care
Setup:
This unit is designed for installation into a standard consumer unit or distribution board by a qualified electrician. It requires a connection to the main incoming power supply and the outgoing circuit for the EV charger.
Compatibility:
- Suitable for 230V/240V AC power supplies.
- Ideal for Electric Vehicle Chargers that do not have integral PME protection, earth leakage protection, overload protection, and require load management.
- Operates on 50/60Hz frequency.
Care:
- Keep the unit clean and free from dust and debris. Use a dry or slightly damp cloth for cleaning; avoid abrasive cleaners.
- Ensure ventilation around the unit is not obstructed.
- Periodically check the "RED" reset button and the unit's housing for any signs of damage.
