Product Information

Full details

The matt:e SP-RC100-SPD is designed for electricians and homeowners installing electric vehicle (EV) charge points connected to a PME earthing facility. Its key benefit is providing a compliant, cost-effective solution for PEN fault protection, integrating essential safety features into a single unit, thereby eliminating the need for additional earth electrodes. A potential consideration is its specific application within single-phase systems.

FAQs

What is PEN fault protection?

PEN fault protection is a safety feature required for EV charging installations connected to a PME (Protective Multiple Earthing) supply. It detects faults where the combined neutral and earth conductor (PEN) becomes disconnected or has a high resistance, preventing dangerous voltages from appearing on the charger's casing.

Do I need an earth electrode with this unit?

No, the matt:e SP-RC100-SPD is designed specifically to provide compliant PEN fault protection without the need for supplementary earth electrodes when connected to a PME earthing facility.

What does 'Load Curtailment' mean?

Load curtailment is a feature that automatically reduces or temporarily stops the power supply to the EV charge point when the total electrical demand in the household exceeds a pre-defined limit. This prevents the main incoming fuse from blowing and maintains stable power for other appliances.

Can this unit be used in a three-phase system?

No, the matt:e SP-RC100-SPD is designed exclusively for single-phase electrical systems.

How often should the unit be inspected?

It is recommended to have the unit visually inspected by a qualified electrician periodically, as part of routine electrical safety checks, to ensure optimal performance and safety.

What is the role of the Type 2 SPD?

The Type 2 Surge Protection Device (SPD) integrated into the unit protects the EV charger and vehicle from voltage surges caused by lightning strikes or other transient electrical events on the power line.

Troubleshooting

EV charge point not receiving power.

Check the main power supply to the unit. Verify that the household consumption load has not exceeded the pre-set curtailment limit. Ensure the unit has automatically reset after the load has reduced. Consult a qualified electrician if the issue persists.

Unit trips frequently.

Investigate the total household electrical load. The unit may be tripping due to high simultaneous demand. Consider reducing the load curtailment threshold if appropriate, or consult an electrician about overall electrical capacity.

PEN fault warning indicator is active.

This indicates a potential issue with the PME earthing system. Immediately stop using the EV charger and contact a qualified electrician. Do not attempt to reset the unit until the earthing issue is resolved.

SPD indicator shows a fault.

The Type 2 SPD may have operated due to a surge event. The unit may still provide basic protection, but the SPD functionality is compromised. Contact a qualified electrician to assess and replace the unit if necessary.

Pros and Cons

Pros

  • Simplifies EV charge point installation by eliminating the need for earth electrodes.
  • Integrates multiple safety features (RCBO, SPD, PEN fault protection) into one unit.
  • Cost-effective solution compared to separate components.
  • Automated load management prevents supply overload.
  • Enhances electrical safety and regulatory compliance.

Cons

  • Limited to single-phase installations.
  • Requires careful setup of load curtailment thresholds.
  • The unit itself represents an additional point of failure in the system.

Setup, Compatibility & Care Instructions

Setup:

  1. Professional Installation Required: This unit must be installed by a qualified electrician.
  2. Wiring: Connect according to the manufacturer's wiring diagrams and local electrical regulations. Ensure correct termination for phase, neutral, and protective earth/PEN conductor.
  3. Load Curtailment Setting: The maximum load threshold for the curtailment function should be set by the installer based on the property's electrical capacity and typical usage patterns.

Compatibility:

  • System Type: Primarily designed for single-phase electrical installations.
  • Earthing System: Compatible with installations using a PME (Protective Multiple Earthing) earthing facility.
  • EV Charge Points: Suitable for most standard EV charge points requiring PEN fault protection.

Care:

  • Cleaning: Periodically inspect the unit for dust or debris. Clean the exterior with a dry or slightly damp cloth. Never use solvents or abrasive cleaners.
  • Maintenance: Regular visual inspections by a qualified electrician are recommended to ensure connections are secure and the unit is functioning correctly.
  • Environment: Install in a dry, well-ventilated location, protected from direct sunlight and extreme temperatures.
