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.

DIN-Rail Mount Solid State Relays

Relay with Integrated Heat Sink

Unlike mechanical relays, these solid state relays have no moving parts, so they require less maintenance and last longer, switch faster, and are quieter. They mount on 35 mm DIN rail (also known as DIN 3) for fast installation. An LED indicator lights up when these relays are connected, so you can quickly confirm that they’re wired correctly. IP20 rated, their terminals are recessed, so they prevent fingers and other objects from touching live circuits.

Relays with an integrated heat sink disperse heat to increase the relay’s current rating.

Infrequent-Cycle Relays

2 Circuits

3 Circuits

For use with equipment that cycles on and off, these relays meet UL 508 for air conditioning and heating. Connections are accessible from the front, so you can mount relays side-by-side. Also known as definite-purpose contactors.

Also Available: Auxiliary contacts for 3.8"-7.2" Ht. relays. They allow you to add a signaling device or control another relay. Please select 6564K99, then select the McMaster-Carr part number of your relay and whether you want to switch one circuit on (1 Normally Open) or off (1 Normally Closed).

Spade-Terminal Relays

Using a low-current signal, these relays are often used to control small motors and heaters. These relays attach to quick-disconnect terminals.

Surface mount relays, also known as power relays, have a slot on the flange for mounting them to flat surfaces.

Relay-socket mount relays, also known as ice cube relays, offer three ways to connect. Plug them into a socket (sold separately), connect them with quick-disconnect terminals, or solder wires directly to the terminals.

Relay-socket/surface mount relays can plug into a socket or mount to a flat surface.

Relay sockets mount directly on 35 mm DIN rail (also known as DIN 3 rail) for fast installation. They can also mount to a flat surface.

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.

Machine-Guard Relays

The interlocked opposing contacts won't close at the same time, so these relays are suitable for safety applications such as machine guarding. The screw terminals are recessed to prevent accidental contact with live connections. Mount them on 35 mm DIN rail (also known as DIN 3 rail) or flat surfaces. These relays are built to IEC dimensional standards.

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