Power Plus EPL and D2L Series Explosion-Proof Panelboards

PowerPlus™ Series Panelboards provide both premium factory sealed and value non-factory-sealed solutions for the protection and distribution of lighting, power, and heat tracing circuits. This panel solution is designed, engineered, and manufactured to be the industry’s safest and most dependable panelboard for hazardous area locations.

Premium Solution: PowerPlus factory sealed panelboards are premium panelboards that provide maximum circuit flexibility with labor savings during installation, operation, and maintenance, and are accommodating for future changes in the field (order with either “S” or “A” in base part number). Panels are pre-wired to maximum circuit capacity, allowing for easy and safe replacement or installation of components in the field, while maintaining factory-sealed integrity.

PowerPlus non-factory sealed panelboards are value panelboards that offer maximum circuit flexibility and many of the same features and benefits of the PowerPlus premium line. This value solution is provided without terminal housing and factory wiring of circuits (order with “N” in base part number). The non-factory-sealed solution reduces initial panelboard material costs and requires field wiring to circuit breakers and external seals to be field-installed during installation.

EPL and D2L PowerPlus™ panelboards are used:

  • In areas made hazardous by the continuous or abnormal presence of flammable gases, vapors, and combustible dusts In areas subject to weather, dampness, and corrosion
  • For branch power distribution and circuit protection to motors, valves, pumps, lighting, heat tracing, receptacles, etc.
  • For indoor and outdoor applications in petroleum refineries, chemical and petrochemical plants, and other process industry facilities where similar hazards exist
  • To accommodate up to 100 amp branch loads (only 3 circuits), balance is up to 50 amps
  • Circuit breaker enclosure body and cover – copper-free aluminum
  • Terminal housing – type 316L stainless steel (“S”) or copper-free aluminum (“A”)
  • Gasket – neoprene (cast aluminum enclosure); foam-in-place (stainless steel enclosure)
  • Operating handles – copper-free aluminum
  • Operating shafts and bushings, cover bolts, washers, hinges, breather/drain, retractile springs – stainless steel
