Product Information

Full details

This Lewden SPD Kit (SRG1VCU-RM) is designed for homeowners and electricians seeking robust protection for electrical appliances against impulse surge effects in Low Voltage (LV) supply systems. Its key benefit is providing universal application across various network systems (TN-C, TN-S, TT) with a maximum discharge current of 20kA. A potential caveat is its IP20 rating, meaning it is not suitable for wet or outdoor environments without additional protection.

Troubleshooting

SPD indicator light shows fault

This indicates the SPD has operated and may need replacement. Consult the product manual or a qualified electrician.

Main switch or MCB trips frequently

Check downstream wiring for faults or short circuits. If the issue persists after inspection, the SPD itself might be faulty and require professional assessment.

No power to protected circuits

Verify that the main switch and MCB are in the 'ON' position. Check all wiring connections for tightness and correct installation.

Pros and Cons

Pros

  • Provides high-level surge protection (20kA)
  • Versatile compatibility with multiple network types
  • Easy integration into existing or new electrical panels
  • Complete kit includes essential components for installation

Cons

  • IP20 rating limits use to dry, indoor environments
  • 1-year guarantee may be shorter than some competitors

Setup, Compatibility & Care

Setup:

  1. Mounting: Securely mount the enclosure onto a standard Din rail within an electrical panel.
  2. Wiring: Connect the incoming power supply to the main switch and then to the SPD unit. Ensure correct polarity and use appropriate cable sizes (up to 25mm²).
  3. Load Connection: Connect outgoing circuits to the MCB and then to the protected appliances.
  4. Grounding: Ensure a robust earth connection is made to the SPD and the main earthing system.

Compatibility:

  • Network Systems: Compatible with TN-C, TN-S, and TT systems.
  • Downstream Protection: Can be installed before or after RCCB/RCBO circuit protection devices.
  • Cable Size: Supports incoming and outgoing terminal capacities of up to 25mm².

Care:

  • The enclosure should be kept clean and dry. Wipe with a dry or slightly damp cloth if necessary.
  • Regularly inspect for any signs of damage or wear. Ensure all connections remain tight.
  • Avoid exposure to moisture or corrosive substances due to its IP20 rating.
