NEMA 1 | NEMA 1 with NEMA 3R Power Inlet Box | NEMA 3R |
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.
NEMA 1—NEMA 1 switches should be used indoors.
NEMA 1 with NEMA 3R Power Inlet Box—NEMA 1 switches with a power inlet box create a connection point between the switch and a portable generator. These switches should be used indoors. But their inlet box is rated NEMA 3R, so it can be mounted on the outside of an exterior wall.
NEMA 3R—NEMA 3R switches can be used outdoors since they seal out rain, snow, and sleet.
Key Lock—Switches with a key lock prevent unauthorized changes to the switch.

Automatic Transfer Switches for Facility Lights
 |
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.
