Raintight Enclosed Motor Switches
 |
Start and stop motors outdoors and in other wet environments. Rated NEMA 3R, these switches seal out rain and light splashes. They’re housed in a protective aluminum enclosure, so you don’t need to mount them inside an electrical panel. The enclosure is lighter in weight than stainless steel enclosures yet still stands up to water and oil.
In addition to turning motors on and off, these switches work with other circuits, such as lighting and electric heat circuits. They do not provide overload protection.

Enamel-Coated Steel Housing and Powder-Coated Steel Housing—The enclosure is steel, so it withstands tougher conditions than plastic enclosures.
Fuse Holder—Use switches with a fuse holder where overload protection is needed. When the current exceeds the rating of the fuse, it blows. This interrupts the circuit and prevents overheating, damage, and fire. When used with UL Class RK1, RK5, or T fuses, they require rejection-style fuse clips. Note: Horsepower ratings are based on time-delay fuses installed.
Lockout—They have a lockout to secure in the off position using a padlock (not included).
Safety Interlock—Switches with safety interlock keep the door closed when the switch is on and prevent the switch from turning on when the door is open.
Viewing Window—Switches with a viewing window let you see the switch position without opening the enclosure.
NEMA 3R Enclosure Rating—A raintight NEMA 3R rated enclosure protects these switches from falling liquids and light splashing.

Enclosed Disconnect Switches
 |  |
Power Pole | Neutral Pole |
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.
Use additional power poles to control more than three circuits. Add neutral poles to open and close the neutral leg of a three phase system.

Two-Circuit Switch with Lockout |
Lockout—Switches with lockout secure in the off position with a padlock with a maximum shackle diameter of 5/16” (not included).
Photovoltaic—Photovoltaic switches can be used with photovoltaic cells which convert sunlight into electricity.

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 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.
