  1. The FastBus System made easy Overview

  2. The Fast Bus system at a glance Fast Bus is a 3-phase busbar system for power distribution. The modular design provides the flexibility needed to fit your application. Fast Bus also carries domestic and international approvals, which make it ideal for a global panel design. Fastbus helps provide for quick maintenance, reducing down time.. Adapter shoes can be easily snapped on or removed from the Busbars in seconds and many of the starters and circuit breakers come pre-assembled from Siemens. Overview The Fastbus system can help you save panel space by allowing you to wire and mount circuit protection and motor starters in a tight line. Leave space for future system expansion.

  3. The 8US Fastbus system at a glance Ideal for Large Systems • The Fastbus System reduces installation cost and time by improving mounting density in panels and speeding up installation time with faster mounting and fewer power connections Overview

  5. The Fast Bus system at a glance Choosing components – Pre-assembled or kitted and ready to go. Overview 3RA11 Non-Reversing and 3RA12 Reversing Combination Starters – Come pre-assembled and ready to place on to the Busbar assembly FBCB***M Fastbus Main Circuit breakers – Offers a full range of Main Circuit Breakers from 100A to 250A pre-packaged with Fastbus adapters and ready for quick assembly FBCB Fastbus Circuit breakers – Offer a full range of Circuit Breakers from 15A to 250A pre-packaged on Fastbus adapters and ready to place on the Busbar FBT250 Three Pole Lug Plate with cover (8US1921-1AA00) 8US1921-1GA00 (FBC84) –Cover for the 8US1921-1A000 Provides terminals for the incoming supply or to jumper from one run of Fast Bus to another.

  6. Designing a Fast Bus System Step Purpose • Determine the total amperage of the required loads • Select method to power Fastbus • Circuit Breaker up to 250A • Main Lug up to 600A • If the sum of the loads is greater than 250A, a separately mounted circuit breaker must be wired to a main lug kit • Select 3RA factory assembled combination starters for each motor load • Select any additional circuit breakers or lugs required to feed non-motor loads or motors greater than 100A • Select appropriate length busbar, busbar support kit(s), insulation covers and any other required components • To decide between 362A and 564A busbar and main lug or circuit breaker • Determines how much busbar space will be taken up by the incoming feed • Determines how much busbar space will be taken up by each starter • Determines how much busbar space will be taken up by each circuit breaker or lug kit • Determines if multiple runs of Fastbus will be required to handle all loads(Note any panel width limitations) Selection

  7. Step 1 – Determine total amperage of required loads Due to the nature of Fast Bus, most applications are considered Group Installation per NEC 430-53 Group Installation is an approach to building multiple motor control systems. In Group Installation, multiple motor starters can be grouped under a short circuit protective device. The 3RA Combination Starters have been UL listed for Group Installation in conjunction with Fast Bus. Selection • Review the specification or line drawing to determine all of the loads in the circuit • Use the calculations below to determine the size to the Short Circuit Protective Device Circuit Breaker Selection - Select a circuit breaker (CB) between: Minimum CB size (per NEC430-110) = Sum of all motor Full Load Currents x 115% Maximum CB size (per NEC430-53c) = 250% x FLC of the largest motor + FLC of all other motors Fuse Selection - Calculate the maximum fuse size per NEC 430-53c: Maximum Fuse size = 175% x FLC of the largest motor + FLC of all other motors

  8. Step 2 – Select Method to Power Fast Bus For Short Circuit Protection from 100 to 250A, we recommend using the FBCB***M Fastbus Main Circuit breakers – These circuit breakers have the Fast Bus wires on the load side. Incoming power wires can be fed through the top of the enclosure directly to the line terminals of the circuit breaker. A Rotary or Max-Flex handle operator can be added to disconnect and lock the breaker in the off position.

These lug kits could also be used to jumper from one run of Fast Bus to another. Lug Kit RatingWidth FBT250 440A 84mm FBT350 460A 135mm FBT600 560A 135mm

  9. Step 2 – Select Method to Power Fast Bus Working from components – Do it yourself If you want to make the Main Circuit Breaker assemblies using circuit breakers you already have in stock, then you can add the FBS250108M (terminals on bottom for the Main Circuit Breaker) or the FBS250108 (terminals on top for the Feeder Circuit Breaker) FastBus Adapter to your inventory. This adapter will accept E and F frame circuit breakers Selection

  10. Step 3 – Select Combination Starters Starter Selection Process • Non-reversing or reversing motor? • Full Load Current of the motor? • Control Voltage? • Number of auxiliary contacts required on the MSP and on the Contactor? • The 3RA devices can be ordered without any auxiliaries or they can be ordered with one SPDT contact block that plugs in to the top front of the MSP and one NO contact block that mounts to the front of the contactor • We recommend using front mount or plug in auxiliary contact blocks to keep the device width to a minimum • Regardless of which version is ordered, additional auxiliary contacts can always be added in the field • These starters can also be built from stock components. • For quick component selection, use Section 5 of the catalog to select a 3RA factory assembled version. To the right of the 3RA catalog number, you will find a list of the components required for field assembly • To see a detailed visual of how to assemble these starters, see the next page or refer to pages 5/33 through 5/36 of the catalog.

  12. Step 4a – Select Additional Circuit Breakers or lug kits To feed non-inductive loads or motor loads greater than 250A, we recommend using the FBCB*** Fastbus Feeder Circuit breakers – Circuit breakers with Fast Bus wires on the line side. These breakers could feed: • non-inductive loads up to 250 A • motor loads not controlled by an MSP/Contactor combinations (Soft Starters, Drives, NEMA starters) BreakerRatingWidth FBCB015 15A 107mm to FBCB080 80A 107mm FBCB100 100A 107mm FBCB125 125A 107mm FBCB150 150A 114mm FBCB175 175A 114mm FBCB200 200A 114mm FBCB225 225A 114mm FBCB250 250A 114mm Selection To feed circuits with separate short circuit protection up to 440A, use the FBT*** Three Pole Lug kits – Kits of 3 individual lugs used to feed additional circuits or to jumper from one run of Fast Bus to another. Also order the FBCB84 cover to prevent accidental finger contact with the terminals. Lug KitsRatingWidth FBT166-1 180A 12mm ea. FBT122-1 270A 16mm ea. FBT620-1 400A 24mm ea. FBT6250-1 440A 21mm ea.
