Description
The OMRON G3NA-440B-2 is a high-performance Solid State Relay (SSR) designed for heavy-duty industrial applications requiring high current switching. This relay features a robust “hockey puck” design with screw terminals, providing reliable control of AC loads up to 40A. It utilizes semiconductor switching technology for silent, fast, and maintenance-free operation, making it ideal for controlling heating elements, motors, and other high-power devices. With built-in zero-cross function for reduced EMI and a wide load voltage range of 180-528VAC, this SSR offers superior performance in harsh industrial environments.
