As standard an auxiliary tag is provided on the motor which states: "Maximum exposed internal and external surface temperatures shall not exceed 200ºC under usual service conditions (sinewave power) at 1.0 SF." If required, a UL Div 2 nameplate maybe ordered as a custom feature. The new nameplate will exclude the motor capability on a variable frequency drive unless supplied for technical review. Net price $200 per motor.

GE has developed and patented a thermostatically controlled space heater. These heaters operate with a maximum surface temperature of 140ºC and are provided with a hermetically sealed thermostat so they do not spark in an end of life event. In most cases when a motor is shut down, the space heaters are immediately turned on. As the motor may take many hours to cool down, the heaters being automatically turned on can result in a cumulative heat that may result in temperatures that approach the 80% Auto-Ignition Temperature (A.I.T.) limit. A thermostatically controlled heater will not allow the heater to energize until the motor has sufficiently cooled down (below 140ºC thermostat reset temperature) thereby not allowing the temperatures to exceed the stated AIT.
