Performance Data

Table 5. Motor Data & Power Codes

Power Code A:

 Motors are 115 volt, 60 Hertz, single phase, totally enclosed with built-in thermal overload  protection and a permanent split 

capacitor to minimize current draw.

Power Code G:

 Motors are 230 volt, 60 Hertz, single phase, totally enclosed with built-in thermal overload protection and a permanent split 

capacitor to minimize current draw.

Power Code I:

 Motors are 230/460 volt, 60 Hertz, three phase, totally enclosed  polyphase induction type.

Power Code V:

 Motors are 115/208-230 volt, 60 Hertz, single phase, explosion-proof, totally enclosed with built-in thermal overload protection 

split phase type.

Explosion proof motors are suitable for Class I, Group C & D; Class II, Groups F & G; Class III. Canadian Standard Association (CSA) require-

ments state that the explosion proof units may not be used with a fluid temperature in excess of 329˚F or pressures greater than 87 psig and still 

maintain their explosion proof rating for National Electric Code ignition temperature rating T3B for grain dust. Class I, Group D Motors are for 

operations in areas containing gasoline, petroleum, naphtha, benzene, butane, propane, alcohol, acetone, lacquer solvent or natural gas. 

Class II, Group F motors are for operations in areas containing carbon black, coal or coke dust. Class II, Group G motors are for operations in 

areas containing flour, starch or grain dust. Class III motors are for operations in areas containing easily ignitable fibers and flyings.
