DIN-Rail Mount Touch-Safe Screw Terminal Relays

Quickly and safely mount these relays on 35 mm DIN rail (also known as DIN 3). IP20 rated, they have recessed terminals that prevent fingers and other objects from touching live circuits.

Relays that control 3 and 4 circuits are built to IEC dimensional standards and are often called IEC contactors.

Auxiliary contacts (sold separately) allow you to add a signaling device or control another relay. You can add one auxiliary contact to all of these relays. For relays with 12 terminals, you can add two side-mount auxiliary contacts.

Solid State Screw Terminal Relays

1-Circuit Relay

Heat Sink

With no moving parts, these solid-state relays are fast switching and require less maintenance, last longer, and are quieter than mechanical switches.

Heat sinks disperse heat to increase the relay’s current rating. Mount them to 35 mm DIN rail (also known as DIN 3 rail) for fast installation. They also mount to 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.
