Hazardous Location Enclosed Disconnect Switches
With a housing that’s designed to contain an explosion, these switches are safe to use in areas where ignitable concentrations of flammable or combustible gas, dust, or fibers may be present. They meet NEC Class I Div. 1 and 2, Groups B, C, D, and Class II, Div. 1 and 2, Groups E, F, and G. Use them to cut power and keep it isolated, so equipment won’t accidentally start up during inspection or maintenance.
Made from aluminum, these switches also resist corrosion in wet or oily areas. They have a lockout, so you can secure them in the off position with a padlock (not included).

Manual Override Enclosure Disconnect Switches
Keep power running while you access your enclosure. Unlike standard enclosure disconnect switches, which shut off power as you open your enclosure, these have an override function. Engaging the override allows you to take voltage reading, troubleshoot an error code, or fine tune the speed of your line. When the override is off, these work like a standard disconnect switch—a safety interlock prevents your enclosure from opening when power is on. The interlock also prevents the switch from turning on when the door is already open. Cut the shaft to fit your enclosure. All have a lockout so you can secure them in the off position with a padlock (not included).
Add auxiliary contact blocks to send a signal or connect to another device, such as an alarm or indicating light.
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.
Add junction blocks to connect a ground wire.
Terminal covers prevent contact with live terminals.
