Omron G3NA-240B-UTU AC100-240 Solid State Relay — Surface Mount, Zero-Crossing SSR, 1-Pole 40 A Output, 24–240 VAC Load, 100–240 VAC Control

The Omron G3NA-240B-UTU AC100-240 is a high-performance solid state relay (SSR) designed for reliable ON/OFF control of AC loads in industrial automation and equipment applications. It features a zero-cross switching function that reduces electrical noise and stress on connected equipment by switching the load near the zero-voltage point of the AC waveform.

Rated for 40 A output current and compatible with loads from 24 to 240 VAC, this single-pole (1-pole) SSR is suitable for controlling heaters, motors, lighting, and other AC devices. The relay is powered by a 100–240 VAC control supply, making it easy to integrate into standard industrial panels.

Designed for surface mounting with screw terminals, the G3NA-240B-UTU provides robust performance with photocoupler isolation and excellent electrical endurance. It supports a wide operating voltage range and works across a broad temperature spectrum, ensuring dependable function in demanding environments.
