Circuit breakers for protecting against short-circuit currents
DANGER
Hazardous Voltage.
Can Cause Death, Serious Injury, or Property Damage.
Health hazard from automatic hot restart.
The 3RM1 motor starter and the safety function must be checked after every tripping of the
motor starter protector (also in the case of overload).
Replace a defective 3RM1 motor starter after a short circuit and check the safety function of
3RM11/3RM13 Failsafe motor starters.

Infeed options
You have the following options for implementing the infeed for the main circuit of the 3RM1
motor starter:
● Infeed via parallel wiring of individual 3RM1 motor starters
● Infeed via the 3RM19 infeed system (for 3RM1...-1AA.4 motor starters with screw
connections and 3RM1...-3AA.4 motor starters with hybrid connections)
