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.

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. They mount directly to 35 mm DIN rail (also known as DIN 3 rail) for fast installation. These relays have recessed terminals that prevent fingers and other objects from touching live circuits.

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

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. 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.

Relays with an integrated fan are best for applications that generate more heat. The fan automatically turns on to provide additional cooling. When the temperature exceeds 176° F, an alarm sends a signal to an external device, such as a controller or indicating light.

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).

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.

Spade-Terminal Relays

Surface Mount

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 have a slot on the flange for mounting them to flat surfaces.
