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. Those with 12 terminals let you attach the control circuit onto the side that works best for your setup, which reduces the amount of wire you need.
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.
Use replacement coils to swap out a broken coil or change the input voltage of a relay. They are only compatible with relays that have 12 terminals. The full load current of the relay must match the full load current range of the coil.

Solid State Screw Terminal Relays
With no moving parts, these solid-state relays are fast switching and require less maintenance, last longer, and are quieter than mechanical switches.
Relays with high-starting-current protection are designed with integrated circuits that prevent damage from the large burst of electricity when a device, such as a motor or pump, turns on.
Relays with LED indicator let you quickly spot whether a relay is on or off.
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 or a thermal pad should be placed between the heat sink and relay. Silicone compound is sold separately for heat sinks that do not include it but require it. Two-circuit relays don’t require silicone for mounting.
