Expanding DC power relay portfolio

Omron Electronic Components Europe has extended its family of DC power relays with the G9EC-X1, a compact relay offering switching up to 1,000V, 150A DC loads. Applications include DC safety shutdown for fast chargers, plus rapid shutdown junction boxes and commercial/industrial PV inverters.

Switching and driving sections are gas-injected and hermetically sealed, letting the relays interrupt high-capacity loads. The sealed construction requires no arc space, saving space and helping ensure safe applications.

The relay measures 98 by 44 by 86.7mm and carries approval to UL/CSA standard UL508. Life is rated at: 1,000 operations at 1kVDC, 150A; 6,000 operations at 1kV, 100A; and 3,000 operations at 400VDC, 200A.

Contact resistance is <0.5Ω, reducing heat generation. Thus, the device can stand a continuous carry current of 200A at 85°C. Dielectric strength is 4,000VAC between coil and contact as well as between contacts of the same polarity.
