Omron offers DC power relays that enable DC load interruption at high voltage and high current, which allows downsizing, weight saving, and non-polarization in the main contact circuit (contact terminal) by using a proprietary design of the contact block. The relay contributes to improvements in the ease of wiring and mounting and error-proofing against faulty wiring. They also offer half-size reduction in volume and weight when compared to Omron’s same class product (60 A, 400 VDC) and is the smallest in its class: 50 mm x 28 mm x 40 mm (H x W x L).
