Thermistor protection req'd in Class II Div II Group F or G ?
Thermistor protection req'd in Class II Div II Group F or G ?
(OP)
Do electric motors to be used in a Class II Div II Group F or G environment require more than mere short circuit and overload protection, i.e., do they require thermistor protection also?

However if you decide to use PTC-thermistors, overload protection and i.e.they should be EX-certified.
Here in Bulgaria we have a Ex-proof PTC-thermistor (they are VERY MUCH MORE expensive than the standard ones).

But since you couldn't be bothered to tell us where you are located, it's hard to say for sure.

I've never run into any requirement for motor temperature monitoring in hazardous locations.
