Overview

Rail-adaptable built-in components, such as NEOZED and

DIAZED bus-mounting bases, adapters for modular installation

devices, fuse switch disconnectors and NEOZED bus-mounting

fuse switch disconnectors are made of glass-fiber reinforced,

thermoplastic polyester. The material ensures the required

mechanical, chemical and electrical properties.

Efficient power distribution up to 630 A. Users have several

options for mounting the SR60 busbar system:

1. Mounting in distribution boards

The busbar supports are mounted on the longitudinal stays.

Once the built-in components are mounted and connected, the

touch protection cover (section cover) protects against acciden-

tal 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: touch protection over base

and edges or touch protection over partitions.

Higher overall efficiency and cost savings in the plant engineer-

ing industry.

The fuse holders for cylindrical fuses, size 10 x 38 and for

American fuses, Class CC, can be used in the international plant

engineering industry. In addition, Siemens offers a broad range

of UL-approved components for the design of switchgear as-

sembly according to UL 508 A.

For further information,

see chapter "BETA Devices according to

UL Standards" in Catalog LV 16 · 2009.

Fuse holders are available with a connection module 16 mm²

and screwless terminals; this offers users maximum safety and

comfort.

Benefits

• The direct contact of the rail-adaptable switching and installa-

tion devices on the Cu busbars reduces distribution panels

and mounting times

• Compared to conventional installation, the transfer resistance

of the connections is drastically reduced This prevents

unnecessary temperature rise.

• New built-in components with touch protection ensure com-

prehensive touch protection without the previously required

partitions.

• International application due to UL-approved components.

• Enhanced effectiveness and increased safety due to screw-

less terminals.
