Good To Know

Q: What does random turn on mean in an SSR? A: Random turn on means the SSR switches on at any point in the AC cycle, allowing phase-angle control for soft-start or dimming applications, unlike zero-cross SSRs that switch at zero voltage.

Q: Is heat sinking required for this relay? A: Yes, for continuous operation at 40A, proper heat sinking is essential to maintain the rated current capacity and prevent thermal shutdown.

Slight variation in finish or dimensions may occur between production runs, and confirm compatibility before ordering.
