Fuse module for the use of 3RM1 motor starters on 8US busbar systems and mounting rails
The fuse module permits the very compact construction of a
load feeder with a maximum width of 22.5 mm. The 3RM1 motor
starter in combination with the integrated fuses for short-circuit
protection can thus be used in this way on 8US busbar systems.
By means of different adapters, the fuse module can be used in
all 60 mm busbar systems and also in compact busbar systems,
as well as on mounting rails. The interface to the adapter also
permits a simple and secure replacement of the load feeder.
The fuse module can be combined with all 3RM1 motor starters.
The easily replaceable fuses protect the connected motor and
the cables.
By means of the fuse module, 3RM1 motor starters can be used in busbar systems and 8US compact busbar systems as well as on
mounting rails
