Features
Siemens
exclusive
feature
QuickConnect™
QuickConnect reduces bussing
connections from many to
one- ensuring a single reliable
connection instead of multiple
connections.
Mounting ear
Pivot factory installed mounting ears
to minimum or maximum position
to provide additional stability when
mounting equipment onto wall.
QuickTorque™
Eliminates the need for time
consuming torque readings,
this breakaway nut provides the
correct indication of torque of the
QuickConnect. When tightened, the
outer head twists off at the proper
torque for connection, leaving a
single nut for future maintenance.
Siemens
exclusive
feature
QuickBolt™
QuickBolt eliminates the requirement
to line up mechanical connectionsinstead bolts remain retracted until the
openings lineup - allowing the bolts to
protrude through automatically.
Springs push the bolts through and
provide positive pressure to keep bolts
in place while wingnuts are attached
and tightened.
Siemens
exclusive
feature
QuickRoll™
QuickRoll eliminates the typical metal
brackets for mounting modules to the
wall. Instead of metal scraping metal
QuickRoll allows the module to glide
down the mounting rail via a durable
nylon wheel inside mounting bracket.
