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.

Touch-Safe DIN-Rail Mount Infrequent-Cycle Relays

Operate equipment that cycles on and off from your control cabinet. Often called definite-purpose contactors, these relays meet UL 508 for use with air conditioning and heating. Mount them directly to 35 mm DIN rail (also known as DIN 3 rail) for fast installation. They have recessed terminals that prevent fingers and other objects from touching live circuits. You can wire the control circuit on either side of the relay, which helps you use less wire.

Auxiliary contacts (sold separately) allow you to add a signaling device or control another relay.

Use replacement coils to swap out a broken coil or change the input voltage of a relay. The full load current of the relay must match the full load current range of the coil.
