In case of coupling overheating with a thermal trip plug, a pin is released and trips a limit switch which gives an alarm or shut off the electric motor.
This method avoids the oil leakage from the coupling.
Fusible trip plugs are available for three different temperatures: 120°C, 145°C and 180°C.
In case of stall conditions, motor running and machine locked, the coupling housing must be driving to guarantee the signal survey.
