1. Application ABB Flexitest switches, types FT-1 (10 pole, rear connected), FT-1F (10 pole, front connected), FT-1X (10 pole, extended terminals, rear connected), FT-14 (14 pole, rear connected), and associated Test Plugs, provide a safe, simple, fast and reliable method to isolate, test, and service installed equipment without disturbing the system.
2. The most complete family of test switches 2.1. FT-1 Standard 10 pole, rear connected test switch. 2.2. FT-1F Surface mount switch allows the user to make the same connections as with FT-1 but on the front of the switch. 2.3. FT-1X Extended length test switch brings the rear terminal connections to the same depth as most panel mounted protective relays and equipment for easier and faster access to wiring points. Extended 8 inches or 10 inches depth is available. 2.4.
2.6. FT-19RS assemblies consist of up to two FT-1 switches, two FT-14 switches, or the combination of one FT-1 and one FT-14 switch mounted on a 19” wide, and two-rack unit (2RU), three-rack unit (3RU), or four-rack unit (4RU) high panel suitable for rack or switchboard mounting. Any combination of FT-1 or FT-14 switches styles may be selected with individual black or clear covers. Non-ABB equipment is not included with the assembly (see circle in picture 9 below).
3. Advantages Flexitest test switches provide a safe, reliable, and cost-effective means to wire the output of relays, meters, and other associated equipment to external devices for in-service testing. 3.1.Safe and convenient All measurements and tests can be performed at the front of the switchboard, without taking any devices out of service, and without the need to access wiring at the rear of the devices.
4. Specifications 4.1. Certifications All Flexitest Switches meet or exceed all requirements of ANSI/ IEEE Standard C37.90. Class 1E switches meet IEEE C37.98, C37.105, 323-1983 and 344-1987 Standards. UL and CUL file number E103204, CSA, and 1E certification are available for most test switches. Contact your ABB representative for more details. 4.2. Ratings All Flexitest switches are rated at 600 Volts AC and 30 Amps. 4.3.
4.4. Construction The base of all Flexitest switches is made of a high grade molded thermo-plastic which provides a tough, insulated enclosure. Barriers are molded into the base (front and rear) to separate the switch units from one another. The barriers provide insulation between poles, and also ample wiring space between terminals. The terminals of the FT-1X are extended either 8 or 10 inches beyond the switch blades located on the front of the switch.
4.6. Poles FT-1, FT-1F and FT-1X switches are available in combinations of 1 to a maximum of 10 individual poles or switch units. FT-14 switches are available in combinations of 1 to a maximum of 14 poles or switch units. Each pole is identified by a letter (A to J or A to N) visible along the top of the base from left to right (front view). Individual pole designations are used to identify each pole according to its type or function.

Screw terminals are provided standard with all Flexitest switches. Connections are made with a hex washer head screw - #8 thread size (0.164-32), 1/4” hex head. Stud and nut terminals are an optional feature. Connections are made with two washers and a nut. A special (5/16”) nut driver can be purchased from ABB to connect to stud terminals, see “Test plug & accessories - ordering information” on page 28. Switch handles with interlocking bar 4.7.

Switch arrangement Pole positions are identified from left to right on the front view of the switch by the letters “A” through “J” or “A” through “N”. Individual pole designations are used to identify each pole according to its type or function.
5. Test plugs 5.2. Individual Current Circuit Test Plug This plug consists of two conducting strips separated by an insulating strip. The ammeter is connected to these strips by terminal screws and leads carried out through holes in the back of the insulated handle. (See figures 2 and 4 on page 14). Figure 6. SafePlug with open CT protection Test plugs used in conjunction with Flexitest switches enable easy measurement, calibration, verification and maintenance of relays, meters and instruments. 5.1.
5.4. Separate Source Test Plug The 10 Position and the 14 Position Separate Source Test Plugs isolate the external connections from the relay or equipment under test. The test plug accepts all common size banana plugs, ring wire connectors, spade lugs and has a through hole for meter probe or wire connections.
6. FT Flexitest switches ordering information FT-1 Configurator ABB has a web based tool to help build any complete FT Switch Arrangement, select options, view schematic details and get style number information. We strongly recommend the use of the web based tool for quick, easy, and user-friendly configuration of Flexitest switches.
Flexitest switch ordering information FT-1 10 pole - Flexitest switch Example style number 1 2 9 A 5 0 1 G 0 1 Style prefix Style numbers are assigned by the factory. Choose from available options by adding style prefix as shown. Individual covers for FT-1 to be used on FT-19R application should be ordered as a separate item. See ordering information table on page 28. None = Black cover, screw terminals.
FT-1F Example style number 10 pole - front connected 1 2 9 A 5 0 1 G 0 1 Style prefix Style numbers are assigned by the factory. Choose from available options by adding style prefix as shown.
6.1. FT-1, FT-1F and FT-1X switches are available in any combination of 1 to 10 poles. Each different configuration of poles is assigned a unique part number or style number by the factory. See ordering information chart for FT-1, FT-1X, and FT-1F on pages 16-17. The standard FT-1 Style Number defines a unique pole configuration with black cover and screw terminals ex: 129A501G01.
6.3 FT-19 and FT-22 test switch assemblies. The FT-19R and FT-19RX assemblies accommodate up to two FT-1 switches. The FT-19RS and FT-22RS assemblies accommodate up to two FT-1 switches, two FT-14 switches, or the combination of one FT-1 and one FT-14 switch. Each different style number is based on a smart part number system. See page 20-22 for more ordering details. 6.3.
