32A Single-Phase AC Surge Protection Box – 6kVA Photovoltaic Protection


The 32A AC protection box is the central safety component for any residential solar installation up to 6.4 kVA. It provides a secure connection between your photovoltaic inverter and the national grid. This JWUN model incorporates high-quality components to ensure the longevity of your equipment against power surges and insulation faults.





Why choose this AC protection box?

  • High immunity (Type A-APR): The 30mA residual current device (RCD) is specially designed to ignore natural leakage currents from inverters, thereby preventing unwanted power cuts.
  • Certified lightning protection: Equipped with a Citel Type 2 surge arrester (2-pole), it diverts atmospheric surges to protect the inverter’s sensitive electronics.
  • All-Terrain Installation: With its IP65 protection rating, this 6-module enclosure is fully waterproof and can be installed both indoors and outdoors.
  • Ready-to-Install Wiring: Pre-wired with HO7-VK flexible cable, the enclosure facilitates connection thanks to its multi-section earth terminals.

FAQ - 32A AC Surge Protector Box (6.4 kVA)

1. Why is the "A-APR" type residual current device essential for my inverter? +
The A-APR (High Immunity) type is specially designed for photovoltaic installations. Inverters naturally generate slight leakage currents which can cause a standard RCD to trip prematurely. This 32A 30mA circuit breaker ignores these parasitic leaks whilst providing genuine protection for people, thereby ensuring the continuity of your solar power generation.
2. What protection does the integrated Citel Type 2 surge arrester offer? +
The Citel surge arrester diverts atmospheric surges (lightning) to earth before they reach the inverter. With a capacity of 20kA (In) and up to 40kA (Imax), it protects your system’s sensitive electronics. It is itself protected by a dedicated 20A circuit breaker, which ensures overall protection is maintained even during maintenance of the surge arrester.
3. Can I install this box outside my home? +
Yes, absolutely. This box has an IP65 protection rating, which means it is completely dust-tight and protected against water jets. It is designed to withstand harsh environments, whether in a damp garage, under a shelter or directly exposed outdoors.
4. What are the connection capacities for earth and the mains supply? +
The enclosure is fitted with a multi-section earth terminal block (2x16mm² + 5x10mm²) to centralise the earthing of the inverter and the structure. For connection to the national grid, the main terminal block accepts copper cable up to 16 mm², ensuring a robust connection that complies with current standards for power ratings up to 6.4 kVA.
