Assembly and mounting

Accessories such as auxiliary switches and surge suppressors can be mounted quickly and
disassembled in just a few short steps. Standard tools are required to disassemble
components only very rarely. Siemens offers a standardized tool (screwdriver 3RA2908-1A)
for disassembling conductors from spring-loaded terminals on all SIRIUS Innovations
products.

Load feeders

Link modules based on screw-type and spring-loaded connection systems are available for
assembling device combinations and fuseless load feeders. The link modules establish the
mechanical and electrical connections for the devices. Motor starter protectors can be
combined with the following devices via link modules:
● Contactors
● Soft starter
● Solid-state switching devices
The SIRIUS Innovations products now also offer a "plug-in connection system" for
assembling load feeders from devices with spring-loaded terminals. Contactors, solid-state
switching devices, and soft starters can be connected to the motor starter protector by simply
plugging them in via a link module:
