DIN-Rail Mount Solid State Relays
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.
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
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).

Washdown Enclosed Relays
A NEMA 4X enclosure protects these relays from washdowns, dirt, and corrosion. It also keeps terminals from being bumped accidentally, so you can mount these relays near working areas. Hardwire to your equipment with the wire leads.

Wireless Enclosed Relays
Send a signal to turn equipment on and off from up to 150 feet away without having to run electrical wire. These relays have an enclosure to protect the terminals from dust and accidental bumps. They can be set to transmit, receive, or both at once. You’ll need at least two relays to switch a device. They have an alarm that can be set to check for certain conditions before transmitting a signal. For example, you could set these relays to send a signal to turn on an air conditioner if all windows are closed. The repeat function extends the transmitting signal through a maximum of two receiving relays.
Relays that are set to transmit can be linked up to as many receiving relays as you need. Relays set to receive can be linked up to 30 transmitting relays. All relays connect to dry contacts on your switch, sensor, or controller. Use the wire leads to connect them to a power source.
UL and C-UL listed, all meet American and Canadian safety standards. Rated NEMA 1, they should only be used indoors.

Heavy Duty Motor Starters
Sealed coils protect these switches against moisture, heat, dirt, and mechanical and thermal stress. They have a solid state overload relay that extends motor life in demanding applications and protects it from overloads—starters will shut the motor off if current exceeds the full-load current rating. The relay is adjustable; set it for the exact overload current needed. All have auxiliary contacts to send a signal or connect to another device, such as an alarm or indicating light. Also known as NEMA starters.
Note: The full-load current rating of your motor must fall within the starter’s overload current range. Match input voltage, also known as coil voltage, to your control circuit; motor voltage may be different. Look for the full-load current rating on the motor’s faceplate, or estimate the current rating (given the motor’s horsepower and voltage).
NEMA contact sizes 0 and 1 are universal mount and fit Cutler-Hammer, GE, and Square D installations.

Enclosed Heavy Duty Motor Starters
Housed in a durable steel enclosure, these switches have sealed coils for protection against moisture, heat, dirt, and mechanical and thermal stress. They have a solid state overload relay that extends motor life in demanding applications and protects it from overloads—starters will shut the motor off if current exceeds the full-load current rating. The relay is adjustable; set it for the exact overload current needed. All have auxiliary contacts to send a signal or connect to another device, such as an alarm or indicating light. Also known as NEMA starters.
Note: The full-load current rating of your motor must fall within the starter’s overload current range. Match input voltage, also known as coil voltage, to your control circuit; motor voltage may be different. Look for the full-load current rating on the motor’s faceplate, or estimate the current rating (given the motor’s horsepower and voltage).
NEMA contact sizes 0 and 1 are universal mount and fit Cutler-Hammer, GE, and Square D installations.
