Solid State Relay Cards These SSRs are sealed units with no moving parts and are particularly suitable for AC Switching applications with high reliability and long operating life. These are PCB mounting and chassis mounting type for R,L & C loads. Low cost short circuit protection is ensured by use of MCB Externally.
Ratings: 2 to 55 Amps/230 to 660 VAC
