Hazardous Location Protection Type
Hazardous Location 30 mm Panel-Mount Key Switches
Designed for use near ignitable gases, fibers, and dust, these switches have a housing that seals in anything that could ignite flammable material. You’ll know they’re safe because they’re NEC Class 1, Division 2 Groups A-D and NEC Zone 1 Groups IIC-IIA certified for hazardous locations. These switches require a key to turn circuits on or off, preventing accidental actuation and limiting access to sensitive equipment. Since they’re keyed alike, all open with the same key. Install them in a standard panel cutout.
Switches that control two circuits come with a contact block for each circuit.
Additional contact blocks (sold separately) can be added to control more circuits, or to replace the included contact block.
