Explosion-proof snap-action switches EDSX, EDS and EFD

The new EDSX series is available with NEMA 4X protection for Class I, Division 2 hazardous locations.

EDS/EDSX and EFD snap-action switches are used with magnetic starters or contactors to control motors. Control panels with snap-action switches are factory sealed to prevent arcing within the enclosed device and prevent ignition of a hazardous atmosphere outside the enclosure. Factory sealing eliminates the need for external seals, simplifies installation, and reduces material and labor costs.
