Panel-Mount Compact Disconnect Switches
Install these switches in a panel cutout. Small enough to fit in tight spaces, they handle comparable electrical loads to standard sized switches. They cut power and keep it isolated to prevent equipment from starting up during inspection and maintenance. All have a lockout so you can secure them in the off position with a padlock (not included). They’re rated IP65 for protection from washdowns.

Enclosed Compact Disconnect Switches
Small yet mighty, these switches are about as tall and wide as an index card yet durable enough to mount directly to a wall. Their polycarbonate housing protects the switch and resists denting, chipping, and cracking. Rated IP65, the housing also seals out water even in frequently washed down areas. Don’t be fooled by their size—these switches can handle electrical loads comparable to a standard sized switch.
These switches cut power and keep it isolated to prevent equipment from starting up during inspection and maintenance. All have a lockout, so you can secure them in the off position with a padlock (not included).

Washdown Enclosed Disconnect Switches
The IP66 rated housing not only shields these switches from washdowns but also makes them durable enough to be mounted outside of an electrical panel. These switches cut power and keep it isolated to prevent equipment from starting up during inspection and maintenance.
Switches with lockout secure in the off position with a padlock with a maximum shackle diameter of 5/16” (not included).
Use additional power poles to control more than three circuits.

Enclosed Disconnect Switches
Cut power and keep it isolated to prevent equipment from starting up during inspection and maintenance. These switches are housed in a protective enclosure that resists denting, chipping, and cracking. Mount them to the wall when you run out of space in an electrical panel.
Switches with lockout secure in the off position with a padlock with a maximum shackle diameter of 5/16” (not included).
Photovoltaic switches can be used with photovoltaic cells which convert sunlight into electricity.

Manual Transfer Switches
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 switches should be used indoors. Those with a power inlet box create a connection point between the switch and a portable generator. The inlet box is rated NEMA 3R, so it can be mounted on the outside of an exterior wall.
NEMA 3R switches can be used outdoors since they seal out rain, snow, and sleet.
Switches with a key lock prevent unauthorized changes to the switch.
