These applications demand high energy efficiency and low heat generation, making Omron's new G9KA relay ideal for grid interconnection and safety interruption. Specifically, it boasts an exceptionally low contact resistance for this type of relay—just 0.2 mΩ—reducing heat generation by more than 30% compared to current equivalent devices. This decreases the need for thermal management components, such as heat sinks or fans, and improves reliability by reducing the heating of nearby components.
The G9KA, measuring 50mm x 50mm x 50mm, offers the advantage of a 30% smaller footprint and lower height than an equivalent contactor. The relay is UL listed and certified to EN/IEC TUV, UL, and CQC standards. It is supplied with PCB terminals and can operate in ambient temperatures up to 85°C.
