Surge Protective Devices

ETEK Solar Surge Protective Devices (SPD) protect electrical equipment from transient overvoltage, lightning strikes, and switching surges. Installed at distribution boards, inverter terminals, and critical loads, they divert high-energy transients to earth before damage occurs.

Our SPD range covers AC SPD and DC SPD, available in Type 1 (Class I), Type 2 (Class II), and Type 1+2 configurations. Built with high-energy MOVs and GDTs, they include thermal disconnectors, visual status windows, and optional remote signaling contacts. Compliant with IEC/EN 61643-11 and IEC/EN 61643-31, ETEK Solar SPDs are essential for building electrical systems, solar PV plants, EV chargers, and industrial automation.
