Overview
The 60 mm busbar system for the medium and top performance range up to 1 600 A, here for example with the 3NP1 switch disconnector, size 3
The 60 mm busbar system is used preferably in control cabinet
installation, in motor control centers and in power distribution
systems of the medium power range (630 A) and top perfor-
mance range (1 600 A, special profile).
The 60 mm busbar system can be configured as a basic system
without covers. The busbar cross-sections are available in the
sizes 12 x 5 mm to 30 x 10 mm and as a special profile.
Busbar adapters for SIRIUS, 3VL circuit breakers, 3KA and 3KL
switch disconnectors, and 3NP1 and 3NP5 fuse switch discon-
nectors offer numerous options for configuring this busbar sys-
tem. Infeed units, terminals and other accessories open up a
large range of applications.
Busbars with a special profile are suitable for applications up to
1 600 A. All components of the 60 mm busbar system can be fit-
ted.
SIRIUS motor starter combinations
SIRIUS motor starter combinations can be configured with and
without fuses.
The compact 3NW7...-1 cylindrical fuse holders for IEC fuses,
size 10x38 mm, or 3NW7...-1HG UL for Class CC fuses are suit-
able for use with fused motor starter combinations.
With a width of 45 mm, SIRIUS motor starter combinations are
the same width as the majority of contactors.
