Power Relays

CUI Devices Power Relays are ideally suited for high-level current switching with maximum switching currents from 5A to 40A. These relays are available in four types of contact forms: SPST (1 Form A), SPDT (1 Form C), DPST (2 Form A), and DPDT (2 Form C). With maximum switching voltages of up to 440VAC or 120VDC, CUI Devices Power Relays feature coil voltages from 5VDC to 24VDC and coil power ratings from 200mW to 900mW. The series is offered in through-hole packages with short leads and a silver (Ag) alloy overlay contact material.
