SSR-40 DA SOLID STATE RELAY

SKU

The SSR-40 DA is a single-phase solid state relay (SSR) designed for contactless switching of high-power AC loads using low-voltage DC control signals. Featuring optocoupler isolation between the control and load circuits, it offers long operational life, silent switching, and high immunity to electrical noise compared to mechanical relays. It is widely used in industrial temperature control systems, AC motor switching, 3D printer heated beds, and automated process machinery.
