Surge-Trap® K PV: next-generation PV protection

A complete range of IEC and UL certified DC surge protection devices designed for the most demanding photovoltaic installations.

Surge-Trap® K PV is the new generation of surge protection devices specifically designed to meet the requirements of the most demanding photovoltaic installations.
Manufactured in Europe under sustainability criteria, the Surge-Trap® K PV range is certified according to IEC and UL standards, guaranteeing the highest levels of safety, quality and reliability.

Surge protection for every photovoltaic installation

Photovoltaic installations are exposed to surges caused by atmospheric discharges and switching operations.
Surge-Trap® K PV protects the most critical points of the installation, from inverter DC inputs to combiner boxes. From residential installations to large-scale photovoltaic plants, it ensures reliable DC-side protection.

THE SOLUTION

Designed for the most demanding PV environments

Certification IEC & UL
Maximum safety and quality ensuring standards compliance.

Imax 50 kA
High discharge capacity to protect demanding applications.

Iscpv 20 kA
High DC short-circuit current capability for robust and reliable protection.

Up to 1500 V DC
Range prepared for modern high-voltage photovoltaic systems.

No back-up fuse required
Simplifies design and reduces components by eliminating the need for external back-up fuse.

5-POLE SOLUTION

All-in-one multi-MPPT protection

The 5-pole version allows two or more MPPT inputs to be protected with a single SPD.

This translates into:

  • Less DIN rail space

  • Less wiring

  • Fewer components

  • Faster installation

  • Lower risk of wiring errors
