Thermal protection
Protect explosion-protected machines against overload according to IEC / EN 60079-14,
Section "Rotating electrical machines".
Use a motor circuit breaker, directly monitor the winding temperature or use equipment to
provide the same functionality corresponding to the explosion type of protection.
For pole-changing motors, in addition to the circuit breaker, use temperature sensors in the
windings.
