These types of applications require high energy efficiency as well as low heat generation, and the new Omron G9KA is a relay solution for grid interconnection and safety interruption. Specifically, it benefits from an exceptionally low contact resistance for this class of relay of just 0.2mΩ, reducing the heat generated in the relay by over 30% compared with current equivalent devices. This reduces the need for thermal management components such as heat sinks or fans and improves reliability by reducing heating of the surrounding components.
Sized at 50mm x 50mm x 50mm, the G9KA offers the benefit of a 30% smaller footprint and lower height than an equivalent contactor. The relay is UL Recognized, and EN/IEC TUV, UL and CQC Certificated. It is supplied with PCB terminals and is rated for use at ambient temperatures of up to 85C.
