Test Switches & Accessories
With over 60 years of experience, ABB is the test switch manufacturer with the largest installed base in North America. The FT Flexitest™ family of test switches is designed and manufactured to allow quick and easy multi-circuit testing of switchboard relays, meters and instruments by any conventional system.
FT Flexitest test switches and related test plugs have the features necessary for applications involving the measurement of individual currents and voltages associated with substation instrumentation and protection devices. They have been especially designed for the measurement of potential elements, current elements, and make-before-break short-circuit elements related to current transformer (CT) circuits.
For applications using Rogowski coil current sensors and voltage sensors, the FT-14D is an innovative digital test switch that incorporates a passive electronic module on the rear with RJ45 connections to the relays and sensors.
Recent additions include the ergonomic separate source test plugs, FT cover shields, FT slotted covers for hanging tags, visible pole markers and reverse current shorting pole option.
