Crouse-Hinds series FLS explosionproof enclosed switches are used in a rigid metallic conduit system as disconnect switches for main feed or individual motor control. They are typically surface mounted adjacent to, or remote from, the equipment being controlled.
FLS switches are certified for Class I and Class II hazardous areas and prevent arcing of the enclosed switch from causing ignition of a specific hazardous atmosphere, or atmospheres, external to the enclosure.
