EXPLOSION-PROOF MOTORS SINGLE PHASE

Transcription

1 AC Motors MOTORS SINGLE PHASE Underwriters Laboratories and Canadian Standards Association Listed These explosion proof motors are designed and approved for application in hazardous environments having certain explosive gases or materials present. 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. Capacitors on single phase designs are mounted inside the motor frame. 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. No LEESON motors are listed for, Group A or B. Please note subheads above each column for qualifications of LEESON motors. Group B: Butadiene, ethylene oxide, hydrogen, propylene oxide, manufactured gases containing more than 30% hydrogen by volume. Group C: Acetaldehyde, cyclopropane, diethyl ether, ethylene. Group D: Acetone, acrylonitrile, ammonia, benzene, butane, ethanol, ethylene dichloride, gasoline, hexane, isoprene, methane (natural gas), methanol, naphtha, propane, propylene, styrene, toluene, vinyl acetate, vinyl chloride, xylene. I Group E: Aluminum, magnesium and other metal dusts with similar characteristics. EXCEPT AS NOTED, STEEL FRAME MOTORS ARE NOT INVERTER-RATED AND MUST NOT BE USED WITH AN INVERTER 32 CAST IRON SEE PAGE 34 Catalogue numbers in blue are NEW items.
