Power Relays

CUI Devices’ power relays are ideal for high-level current switching with max switching currents from 5 up to 40 A. Our power relays feature SPST (1 Form A), SPDT (1 Form C), DPST (2 Form A), or DPDT (2 Form C) contact forms, through hole packages, and silver alloy or silver tin oxide overlay contact material. With max switching voltages up to 440 Vac or 120 Vdc, our power relays carry coil power ratings from 200 to 900 mW and coil voltages from 3 up to 110 Vdc.
