Features

N/A

  • Explosion-proof motors are Class I, Groups C & D-Class II, Groups F & G.Features:
  • Rugged mechanical construction meeting all requirements for safety. UL and CSA listed.
  • Double shielded, pre-lubricated ball bearings are standard.
  • All motors have inherent automatic overload protection.
  • NEMA1.0 Service Factor except as noted.
  • Explosion-proof conduit box included at no extra cost.
  • Division I areas are environments where a hazard is present continuously or would be subject to fire or explosion if the hazard was present as a result of an accident or uncommon occurrence.
  • Division II areas are environments where the threat of fire or explosion is not normally present and not likely to result in the event of an abnormal occurrence.
