3 Introduction General 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. Fast Bus is ideal for industrial applications where system availability is important. Features Simple economical installation Compact design Requires fewer mounting holes Domestic and International approvals Touch safe Modular design Provision for system expansion Clip-on shoes provide mechanical and electrical connections to panel mounted busbars Main and Feeder breakers mount to busbars Benefits Saves installation time Reduces space requirements Minimizes layout time Allows flexibility for domestic and export business Protection for maintenance personnel Improves equipment mounting density Reduces time and costs associated with system expansion Reduces mounting and wiring time and provides trouble free connections Allows for quick retrofitting of breakers How to Select Fast Bus 1) Determine the required load. 2) Select method to power Fastbus. Main lug up to 800A Circuit breakers, 1A to 00A If load exceeds 00A, 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.

4 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 mm or mm widths. Refer to page /6 for selection details. High quality material Busbar supports and fuse bases are manufactured from glassfiber reinforced, thermoplastic polyester with the color RAL 703, 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 8WC03 (20 mm x mm), however there are other styles available depending on your application. Busbar systems with 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 /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 (8US UA01) so that the clearance in air and creepage distance requirements are met. Feeder/branch circuit according to UL 08A 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 (/6) 8US1 Ground busbar support (shown attached however can be mounted separately /6) Ground busbar available in x 20 mm to x 30 mm 8WC Busbar (8WC03 shown) FBB36 Busbar (/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.

5 Introduction Fast Bus combination starters and group installation assemblies Ratings for Group Installations per NEC Group Installation is an approach to building multiple motor control systems in accordance with Section 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.

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 NEC430-1): Sum of all motor FLC (per NEC table ) x11%. Maximum CB size (per NEC430-3c): 20% x FLC of the largest motor + FLC of all other motors. Fuse Selection Calculate the maximum fuse size per NEC430-3c. Max Fuse Size =17% x FLC of largest motor + FLC of all other motors (FLC s from NEC table ).
