Surge Protecting Devices

Surge protective devices, also called SPD, protect electrical systems and equipment from electrical surges. They limit current overloads and surges, which can cause damage to electrical systems and devices. Electrical surges can occur both because of events like lightning strikes, or because of internal surges caused by relays and breakers, or heating systems. Surge protective devices work by limiting or diverting the excess electrical current, and therefore maintaining a safe voltage level.

At Guillevin, you’ll find surge protectors, surge breakers, arrestors and monitors. Our products are available with varied interrupting ratings and voltage options.
