Descriptive Bulletin ABB 41-077 Page 1 April 2002 Supersedes DB-41-077 Dated April, 1998 For Multi-Circuit Testing of Switchboard Relays, Meters and Instruments Flexitest Switch Type FT-1 Figure 1. FT-1 Flexitest Switch (Front View) APPLICATION The ABB Type FT-1 Flexitest Switches and ABB Test Plugs are designed and manufactured to allow quick and easy multi-circuit testing of protective relays, meters and instruments by any conventional system. Advantages The Type FT-1 Switches and related Test Plugs have all the features necessary for applications involving the measurement of individual currents and voltages associated with substation instrumentation and protection devices. The make before break current short circuit feature also allows test personnel to quickly and safely isolate equipment from current transformer (ct) circuits. Safe and Convenient The semi-flush mounted FT-1 Switch provides fast, safe and reliable access to components and circuits on panel boards and switchboards without disconnecting existing wiring. All measurements and tests can be performed at the front of the switchboard without taking any devices out of service. Fast and Reliable When Test Plugs are used, any number of circuits may be tested in rapid succession, since one plug properly connected can test all instruments or meters of a particular type. Maximum Flexibility The FT-1 Switch is built with a maximum of ten individual poles or switch units. The switches can be assembled in a variety of different arrangements, to match customer requirements. ABB Test Plugs are used in conjunction with the FT-1 Switch to enable easy measurement, calibration, verification or maintenance of relays, meters or instruments. Voltage measurements can also be made directly on the FT-1 Switch (without disturbing existing connections). There is a test clip located on the top of each pole that allows connection with standard spring clip test leads. Security With the cover in place, a meter type lead seal can be placed through either of the cover studs of the FT-1 Switch to prevent unauthorized access to the switch. As an additional feature, a clear cover is available that can also be installed and locked with the switchblades in the open position. DB 41-077 Page 2 SPECIFICATIONS This is the same size nut driver that is used on the hex head terminal screws of the standard FT-1 Switch. Ratings The FT-1 Switch is rated at 600 volts and 30 amps. It is UL recognized, and meets or exceeds all the requirements in ANSI/IEEE C37-90 standard. Mounting FT-1 Switches are designed for semi-flush mounting on the front of switchboard panels, facilitating inspection and accessibility. lbs.

(kg) (0.45) FT-1 SWITCH CONSTRUCTION Poles FT-1 Switches are available in combinations of anywhere from 1 to a maximum of 10 individual poles or switch units. Each pole is identified by a letter (A to J) visible along the top of the base from left to right (See Fig. 1).The individual switch units are of a knife blade type. There are two different types of switch units available: potential poles and current poles. Potential poles (P, T, . . .) are configured as single, non-shorting knife blades for use in potential, trip, or control circuits. Current poles are typically configured in sets of two, (C-C), for use with current circuits; and consist of a current test jack, a shorting spring, a shorting blade, and a non-shorting blade. (See Fig. 2) The positions of the short circuit springs are visible from the front of the switch. Base The base of the FT-1 Flexitest Switch is made of a molded polycarbonate material, 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. Cover The cover of the FT-1 Switch provides a tough insulated enclosure for the switch and is also made of a polycarbonate material. FT-1 standard styles come with a black opaque cover, but an optional clear cover is also available. This clear switch cover affords the user the unique option of intentionally leaving switch handles in the open position and replacing the cover. Maintaining the provision for a meter seal when some handles are in the open position allows the user to service electrical equipment while still complying with OSHA tag and lock procedures. The clear cover can be ordered on new FT-1 Switches or ordered separately for retrofit to existing FT-1 Switches. Users will maintain the same ease of accessibility as with the black opaque cover. The cover thumb nut has been modified so that a 1/4" nut driver can be used to loosen & tighten it. Figure 2. Blade assembly of two position pole "C-C" (Rear View, outside of base) Switch Handles Switch handles are made of a molded phenolic material, and are typically black for potential and current circuits, and red for trip circuits. They are also available in a variety of different colors. Each handle has a dovetail indentation to hold a circuit identification label. Knife blade switches can be operated independently, or ganged together with a horizontal interlocking bar, to suit testing needs. (See Fig. 3) A hole runs through the middle of each switch handle to allow insertion of interlocking bars that can mechanically tie 2, 3, 4, 5, 6 or 10 switch handles together. Interlocking Bars are sold separately. (See "ACCESSORIES - ORDERING INFORMATION" on page 8.) DB 41-077 Page 3 Figure 3. Switch Handles Figure 4. FT-1 Switch (rear view) Terminals Connection terminals are located at the rear of the switch. Terminals are numbered 1 to 20 for easy identification (rear view). Each pair of numbered terminals is associated with a matching pole designated by a letter on the front of the switch.

(See Figs. 7 and 8) WARNING When using an In-Service Series Test Plug for current measurements, connections from the Test Plug to the measuring instruments must be made before inserting the Test Plug in place. Figure 7. Individual Current Circuit Test Plug Figure 6. In-Service Series Test Plug The "In-Service" Series Test Plug with a maximum of 10 positions is designed to match the pole configurations of specific styles of FT Flexitest devices (either FT-1 Switches or FT case relays). Not every switch or relay pole configuration is suitable to accept an InService Series Test Plug, but many FT-1 Switch styles do have one already available, See Table 3, page 9, "IN-SERVICE TEST PLUG". This Test Plug is typically used to connect devices measuring the currents and voltages being applied to the switchboard relays, meters and instruments without interrupting or short-circuiting the circuit. Only the current test switches with the current jack must be opened before inserting the Series Test Plug. Figure 8. Individual Current Plug inserted into Flexitest Case Separate Source Test Plug WARNING Provision is made only on current poles with shorting springs to automatically short-circuit current transformer circuits when the knife switches are opened prior to inserting the Test Plug. Individual Current Circuit Test Plug WARNING When using an Individual Current Circuit Test Plug for current measurements, connections from the Test Plug to the measuring instruments must be made before inserting the Test Plug in place Figure 9. Separate Source Test Plug - 10 Position The Individual Current Circuit Test Plug is an ammeter type device used to measure current. It can be inserted in the current test jack of FT Flexitest devices after opening the knife blade switch. 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 The 10 Position Separate Source Test Plug isolates the external connections from the relay or equipment under test. This test plug provides quick circuit testing, by fitting into the stationary contact jaws of any Flexitest Type FT Case or FT-1 Switch. L-shaped test blades assure quick, accurate alignment between the Test Plug and the stationary contact jaws. DB 41-077 Page 7 This Test Plug connects the relay inputs and outputs to a set of binding posts on the top of the Test Plug, and completely isolates the relay circuits from the external connections (ct, pt, trip, etc.) by means of an insulated barrier along the bottom of the plug. The external test circuits can then be connected to these binding posts, which are staggered for easy accessibility. Before inserting the Separate Source Test Plug, all switch- blades must be placed in the full open position. In a Flexitest Type FT Case, the plug is inserted in the bottom switch jaws with the binding posts up and in the top test switch jaws with the binding posts down. (See Fig. 10) Figure 10.
