Who it's for
Keep a spare on the shelf, not a job on hold.
A solid-state relay, or SSR, is an electronic switch with no moving parts. In a powder coating oven's control setup, a PID temperature controller typically pulses an SSR on and off to hold a set temperature, so the relay does the actual switching work.
