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.

If there’s a power outage, flip the toggle for each circuit on these switches to backup power. Each circuit can also be turned off completely. To prevent injury and damage to your generators, they are open transition, meaning the contacts disconnect from one power source before connecting to another. This is also known as break-before-make switching.

Use them with a portable generator.

Housed in a durable steel enclosure, these starters 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 power and voltage).

Restore lighting immediately during power outages. These switches detect when your main power source goes out and shift your lights to a backup, such as a secondary utility source or generator. To comply with UL 924 and help you meet NFPA standards, they turn your lights on at full brightness even if the lights were turned off or dimmed. You can also wire these switches to your fire alarm. Pull the alarm to activate lights to full brightness during emergencies, even without an outage. All have passed testing to meet UL 1008, a safety standard for transfer switches.

An LED indicator tells you whether lights are running on a primary or backup power source. The indicator also tells you when these switches require maintenance.

Remote Testing Buttons—Add a remote testing button to check if switches behind the wall or ceiling are working properly.

Combine a switch with a thermal overload element to build a starter that can handle high-current-rated motors. All are housed in a durable steel enclosure. They’re also known as NEMA starters.

Thermal overload elements shut motors off if current exceeds the full-load current rating. Three elements are required. To Order: Please specify the full-load current rating of your motor. If the full-load current rating is not shown on the motor’s faceplate, estimate the current rating (given the motor’s power and voltage).
