Introduction
General
Features
Benefits
The Fast Bus Multi-Motor Control system
is a 3-phase insulated busbar system
and is ideal for space saving in panel
designs. The system saves considerable
line side wiring and space for multi-motor
panels. It is also ideal for panels where
several feeder breakers are used and will
save significant wiring space and wiring
labor. The system is also ideal for future
expansion planning. when building
control panels. SIRIUS 3RV/3RT starter
combinations and Siemens circuit
breakers are all adaptable to Fast Bus for
convenient mounting and faster replacement times.
• Simple economical installation
• Saves installation time
• Compact design
• Reduces space requirements
• Requires fewer mounting holes
• Minimizes layout time
• Domestic and International approvals
• Allows flexibility for domestic and
export business
• Touch safe
• Protection for maintenance personnel
• Modular design
• Improves equipment mounting density
• Provision for system expansion
• Reduces time and costs associated
with system expansion
• Clip-on shoes provide mechanical
and electrical connections to panel
mounted busbars
• Reduces mounting and wiring time
and provides trouble free connections
• Main and Feeder breakers mount to
busbars
• Allows for quick retrofitting of breakers
Fast Bus is ideal for industrial applications where system availability is
important.
How to Select Fast Bus
1) Determine the required load.
2) Select method to power Fastbus.
—Main lug up to 800A
—Circuit breakers, 15A to 500A
If load exceeds 500A, the CB must be
separately panel mounted and fed to
a main lug infeed module.
3) Select 3RV MSP & 3RT contactor
components and appropriate adapter
shoe or select preassembled 3RA
starters. See section 4.
4) Select appropriate length busbar,
busbar holders, insulation covers
and any other required components.

Fast Bus Busbar Adapter System
Introduction
Fast Bus set-up
The Fast Bus system is designed
to be easy to use and to save
set up time.
8US Busbar holders
The 8US busbar holders are
designed to accommodate
ampacities up to 1400A. In some
cases, the busbar holder will
accept busbars in either 5mm or
10mm widths. Refer to page 5/6
for selection details.
High quality material
Busbar supports and fuse bases
are manufactured from glassfiber reinforced, thermoplastic
polyester with the
color RAL 7035, light gray. The
material ensures excellent
mechanical, chemical and electrical properties. Furthermore,
the material has an extremely
low flammability and meets the
requirements of UL 94 V0.
8WC Busbar and
busbar systems
The most common size busbar
for applications in the US is the
8WC5053 (20 mm x 5 mm), however there are other styles available depending on your application.
Busbar systems with 60 mm busbar center-to-center clearance
have now become firmly established in the US market.
The permissible busbar temperature is a decisive factor when
dimensioning the busbars. The
busbar temperature is dependent on the current, the current
distribution, the busbar crosssection, the busbar surface, the
position of the busbar, the convection and the ambient temperature. The values stated in the
table on page 5/3 can only be
considered as reference values
because the conditions vary
with each location. The values
are based on constant current
over the whole busbar length.
The trend toward busbars
proves most advantageous
when the incoming supply is
centrally located and the load is
distributed symmetrically on
both sides.
For the assemblies of a busbar
system in the feeder circuit the
UL directives specify components with large clearance in air
and creepage distances (see
the table below). Components of
the 8US1 busbar system which
meet this requirement can be
found in this chapter.
Note:
The design of an 8US1 busbar
system for use in the feeder circuit always presumes the use of
the UL base plate (8US19 222UA01) so that the clearance in
air and creepage distance
requirements are met.
Clearance in air
Creepage distance
25.4 mm (1 inch)
50.8 mm (2 inch)
Between live parts and grounded, 25.4 mm (1 inch)
non-insulated metal parts
25.4 mm (1 inch)
Between live parts

Feeder/branch circuit
according to UL 508A
The feeder circuit is that part of
a circuit which comes in front of
the last short circuit protection
device (SCPD). The branch circuit is that part of the circuit
which follows after the last short
circuit protection device. When
the 8US1 busbar system is used
in a switchgear which must
comply with UL directives, it is
important to establish whether it
is to be used in the feeder circuit
or the branch circuit. Components used in the feeder circuit
require larger clearance in air
and creepage distances than in
the branch circuit.
Simple Fast Bus system
The two illustrations above show
the very basic items needed
when setting up a Fastbus system.
8US1 Busbar holder (5/6)
8US1 Ground busbar support
(shown attached however can be
mounted separately 5/6)
Short-circuit strength
The short-circuit strength of the
busbar system is dependent on
the spacing of the busbar holders and on the busbar crosssection.
The short-circuit strength of the
whole system is dependent on
the short-circuit strength of the
busbar system and the
components that are mounted
to the system.
Applications
The 8US Fast Bus distribution
system is ideal for control panel
builders with multiple motor
applications. These applications are most common in the
material handling, automotive,
food processing, pharmaceutical and paper processing
industries.

Ratings for Group Installations per
NEC 430-53
Standard Installation, NEC 430-52
Group Installation, NEC 430-53
Group Installation is an approach to building multiple motor control systems in
accordance with Section 430-53 of the
National Electrical Code. In Group installation, multiple motor starters can be
grouped under one short circuit protective
device. The 3RV MSP’s have been UL
listed for use in Group Installations both
with and without 3RT contactors when
mounted on the Fast Bus system. A 3RT
contactor is added when remote operation of the motor is required.

The selection of components for

1. Selection of the Branch Circuit Protective Device, fuse or circuit
breaker.
2. Selection of the 3RA Motor Starter
based on the motor Full Load Amps.

Circuit Breaker Selection
Select a circuit breaker (CB) between:
Minimum CB size (per NEC430-110):
Sum of all motor FLC (per NEC table
430-150) x115%.
Maximum CB size (per NEC430-53c):

Branch Circuit Protective Device for 480V-Ratings: The appropriate BCPD need to be determined in accordance with the National Electrical Code, Article 430-53 and the
application. The following devices are permitted:
Fuses: Classes RK1, RK5, J, G, T, CC or Circuit breakers: Listed Siemens type, with a marked short-circuit rating equal or larger than the available short-circuit
current rating. These devices were tested for group installation use at the above levels without any upstream branch circuit device.
2) 3RA2 used as Manual Motor Controller; Branch Circuit Protective Device for 600V-Ratings: Max. Class J 50A
3) Starter sizes S00,S0 and S3 require additional type E line side terminal adaptors on the MSP for type F applications. See section 1 accessories
