Explosion-Proof For Hazardous Locations
Underwriters Laboratories and Canadian Standards Association Listed
General Specifications:
These explosion-proof motors are designed and approved for application in hazardous environments having certain explosive gases or materials present.
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.
- NEMA 1.0 Service Factor except as noted.
- Explosion-proof conduit box included at no extra cost.
- Normally-closed thermostats are standard on cast iron motors.
- 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.
Application Notes:
These motors must be applied in accordance with the National Electrical Code, Article #500. A partial listing of explosive agents is noted below. Consult NFPA Publication 497M for a complete listing. Please note subheads above each column for qualifications of LEESON motors.
