    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.

    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.

Features N/A These motors are totally enclosed, non-ventilated.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.
Capacitors on single phase designs are mounted inside the motor frame.
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. 		N/A 56H & 56HC motors have bases with mounting holes for NEMA 56 and NEMA143-5T and a standard NEMA 56C face and 5/8" shaft.Rugged mechanical construction meeting all requirements for safety.
