Kontrolstationer

Crouse-Hinds series EDS explosionproof motor starter control stations are used with magnetic starters or contactors for remote control of motors. EDS motor starer control stations are factory sealed to prevent arcing of the enclosed device from causing ignition of a hazardous atmosphere external to the enclosure. Factory sealing eliminates the need for external seals, simplifying installation and reducing costs.
