  • In areas made hazardous due to the presence of flammable vapors or gases, such as petroleum refineries, chemical and petrochemical plants, gas gathering plants, pipeline compressor stations, and drilling rigs, both onshore and offshore
  • In areas where hazardous dusts are present, such as coal handling facilities, grain processing and handling plants, and certain food process industries
  • Complete factory assembled and wired switch racks
  • Pre-drilled bus boxes allow for quick and easy changing or adding of components
  • Complete assembly covered under one order, eliminating engineering costs, additional costs of placing separate orders with several vendors for various components, and assembly and scheduling problems at job site
  • Wiring is simple. After switch rack is in place, feeders are connected to the main bus and connections made from starters motors. No other field wiring is necessary
