Product Details
Our explosion-proof motors are ideally suited for hazardous environments defined by the motor's explosion-proof class and group rating for use in applications that may contain explosive gases or materials. The motors are UL listed, with frames ranging from 56-145T and 182T-445T classified under class 1 groups C & D and class 2 groups F & G (divisions 1 & 2). Additionally, frames 182T-256T and 364T-449T are also class 1 groups C & D and class 2 groups F & G (divisions 1 & 2). The motors have a capacity of up to 250 HP, with the 449T and 449TS available as class 1 group D and class 2 groups F & G (divisions 1 & 2). The motor construction includes steel frames and cast aluminum end brackets for frames 56 - 145T, while cast iron frames and end brackets are provided for frames 182T and larger. Inverter-rated designs are available, providing a constant and variable torque speed range of 6 to 60 Hz (10:1), and the motors are nameplated for 190/380 volt, 50 Hz operation. They feature a premium class F insulation system, with an automatic reset thermal protector for frames 56-145T or a thermostat for frames 182T-449T. The motors meet the UL frame temperature limit code T3B.
