SPD for Low-voltage Power Systems

Our surge protection devices (SPD) are suitable for lightning & surge protection of low-voltage systems, power supplies, communication networks, PV systems and street/outdoor lighting.

They meet the requirements of UL 1449 Forth Edition and IEC/EN 61643-11.

Depending on the design, they can be mounted on DIN rails in control cabinets, combiner boxes or optimized for installation in street lights.

They are fail-safe, have an fault display and a remote signaling contact.

They are robust and well protected against harsh environmental conditions and meet the requirements for high reliability in important areas.
