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.

Screw Terminal Relays
Use the screw terminals to hardwire these relays. The built-in enclosure protects contacts from dust and dirt. These relays accept voltage drops up to 50% of the rated voltage without switching. They’re often used with industrial automation systems, security and emergency lighting, and small motors. Also known as power relays.

Infrequent-Cycle Relays
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.
Enclosures (sold separately) are NEMA 1 rated to protect contacts from corrosion.
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).

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.

High-Current Lighting Relays
Switch lighting systems on and off—these relays can handle the high switching current on large overhead light systems. They control multiple circuits, so you can manage several lights across your facility with just one relay. For example, use them to switch overhead lights along with lighted signs in different parts of your warehouse. These relays come set for normally-open switching, but you can change them to normally-closed by turning the contacts around with a screwdriver.
Electrically held relays can handle switching on and off frequently. However, because they need constant input voltage to keep the relay switched, they make a humming noise when switched on.
Mechanically held relays are ideal for applications that don’t need to be switched very often, such as lights that stay on all day. Since they switch on and off with a quick burst of input voltage rather than needing constant power, they’re more energy efficient than electrically held relays.
