C&S's DC motor protection system model PEMCC evaluates the rotor solicitation of a dc machine through its current sensing.

You can configure two different operation modes:

It is designed to replace electromechanical or overcurrent relays in general. It is also possible to configure an instantaneous trip.

It’s a special mode in which you can enter the motor physical parameters to analyze the actual thermal state of the machine. Useful, for example, in the case of successive starts or alternate cycles of loading, where TI-2 mode may not contemplate actual heating accumulated due to these efforts. You can also set an instantaneous trip.
