Overview
Rail-adaptable built-in components, such as NEOZED and DIAZED
bus-mounting bases, adapters for modular installation devices,
LV HRC fuse switch disconnectors and NEOZED bus-mounting
fuse switch disconnectors are made of glass-fiber reinforced,
thermoplastic polyester. The material ensures required mechanical,
chemical and electrical properties.
Efficient power distribution up to 630 A.
There are many ways for users to mount the SR60 busbar
system:
1.
Mounting in distribution boards
The busbar supports are mounted on longitudinal stays. Once
the built-in components have been mounted and connected, the
touch protection cover (front cover) protects against accidental
contact with live parts.
2.
Installation in industrial control cabinets
The demand for comprehensive touch protection has generated
new solutions: built-in components, such as busbar fuse bases
have integrated reach-through guards, enable the implementa-
tion of cost-effective overall solutions.
Previously two optional solutions were provided, which can now
be replaced using new technology: the touch protection over
base and the respective edges, or touch protection by means of
partitions.
Overall, increased efficiency and cost savings for the plant
manufacturer.
With fuse holders for cylindrical fuses, size 10 × 38 and for American
fuses class CC, they can also be deployed in the international
plant engineering sector. In addition, Siemens offers a wide
range of UL-approved components for the design of switchgear
assemblies in accordance with UL 508 A.
For further information, see chapter BETA Devices According to
UL Standard in Catalog LV 16 · 2009.
For the ultimate in user safety and convenience, we also offer
fuse holders and connection modules 16 mm² with screwless
terminals.

Benefits
•
The direct contact of the rail-adaptable switching and installation
devices on the Cu busbars reduces distribution panels and
mounting times
•
The transfer resistance of the connections, when compared to
conventional installation, help prevent unnecessary temperature
rises.
•
New touch-protected built-in components ensure comprehen-
sive touch protection without the previously required partitions
•
International implementation due to UL-approved components
•
Enhanced effectiveness and increased safety due to screwless
terminals.
