Function
PTC protects the motor against overtemperatures.
The Trip unit receives the alarm from the

module to which a thermocouple can be connected for the
purpose of monitoring the temperature of the motor: the protection sends a TRIP command if the temperature
measured exceeds 120°C for more than one second.
