Equipment protection
In addition to the motor protection function, the 3RM1 motor starters also protect themselves
against overload. This means that in the case of 3RM1 motor starters with a rated
operational current of 7 A, an overload trip may occur in the upper current range before the
motor protection trips. If, for example, 8-fold current flows in the case of an unloaded motor
model and a set current of 7 A, tripping takes place after approximately one second.
