DANGER
Hazardous voltage.
Will cause death or serious injury.
If free and uncovered terminal lugs are touched when the load voltage is switched on,
death or serious physical injury will result.
For this reason, always cover the free terminal lugs (= free slots that are unassigned for
thermal reasons, for example) with a cover cap. The cover caps are available as
accessories.
Energy is supplied via the infeed terminal 3RM1920-1AA. This means you can connect
conductors with a cross-section of 1.5 mm² to 4 mm².

3RM193 fuse module
A fuse module can be used to create a very compact design of load feeder. The 3RM1 motor
starter in combination with the integrated fuses for short-circuit protection can be used on
8US busbar systems or on standard mounting rails.
The fuse module can be installed using a variety of different 8US adapters:
●
In all 60 mm busbar systems
●
In compact busbar systems
●
On standard mounting rails
The interface to the adapter permits simple and safe replacement of the load feeder.
The fuse module can be combined with all 3RM1 motor starters. The easily replaceable
fuses protect the motor starter, the connected motor and the cables.
Rated operational current
The maximum permissible rated operational current for the 3RM193 fuse module is 25 A.
Assembly
1.
Connect the motor starter to terminals L1, L2 and L3.
2.
Connect up the motor feeder cables.
3.
