Configuration
4.7 Infeed for the main circuit
SIRIUS 3RM1 motor starter
80 Manual, 06/2016, A5E0345285095020A/RS-AE/005
Rated operational current
For the components of the 3RM19 infeed system, the maximum permissible rated
operational current is 25 A (UL: 16 A).
If you use several 3RM1 motor starters that together require more than 25 A, form groups
that each have a maximum requirement of 25 A (UL: 16 A).
Note
Multiple infeed
If you plan multiple infeed in the case of a respective requirement of more than 25
A, you
must observe a potential current asymmetry in the infeeds.
Attach the busbar from below to the rear terminals L1, L2 and L3 of the 3RM1 motor starter.
The outgoing feeders to the motors thus remain accessible.
