Explosion-Proof Starters

Non-combination and combination starters enclosed in Type 7/9 enclosures for safe and reliable starting in hazardous applications

Sprecher + Schuh's offers explosion proof starters for environments covered by NEMA, UL, NEC & CSA classifications.

Type 7 enclosures are designed to provide protection against an internal explosion when operated in a hazardous gas environment. Type 9 enclosures protect from internal explosion in a hazardous dust environment. Both types must also prevent enclosed heat generating mechanisms from causing external surfaces to reach temperatures capable of igniting explosive gas-air mixtures in the surrounding atmosphere. Sprecher + Schuh explosion proof starters meet all requirements of both classifications. Explosion proof enclosures are also equipped with a watertight Nitrile gasket for compliance with Type 4 specifications.
