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.

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

12 Terminals—Relays 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.

Accessories and Replacements for Relays

Relay Contacts


Front Mount	Side Mount

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

Replacement Relay Coils

Image of Product. Front orientation. Relay Coils. DIN-Rail Mount Touch-Safe Screw Terminal Relays.

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.
