FOTEK SSR-40VA 40A Solid State Relay, 24–380V AC Output

Description

The FOTEK SSR-40VA Solid State Relay is a single-phase electronic switching device designed for controlling AC loads. Unlike a conventional electromechanical relay, it uses solid-state components to switch the load without mechanical contacts.

This model belongs to FOTEK’s SSR-VA series and uses a variable-resistor input with an AC output. The manufacturer lists a 24–380V AC load-voltage range and a maximum rated load current of 40A. The marking on the uploaded image also shows a 500kΩ input-resistance specification associated with 220V operation.
