With no moving parts, these solid state relays have an extended service life.

Two-circuit relays are rated IP20 for protection against solid objects greater than 12.5 mm, such as fingers. They’re not water resistant.

Heat sinks can be used to disperse heat to increase the relay’s current rating. Mount to 35 mm DIN rail or flat surfaces. Before mounting one-circuit relays, silicone compound should be applied between the heat sink and relay. Silicone is sold separately for 75A and 90A one-circuit relays. Two-circuit relays don’t require silicone for mounting.
