The FT Switches and FT Test Plugs have all the features necessary for applications involving the measurement of individual
currents and voltages to facilitate testing of substation instrumentation and protection devices from the front of the panel.
The make before-break current short circuit feature allows test personnel the convenience of isolating equipment from current
transformer circuits.
Voltage measurements can be made directly on the FT Switch without disturbing existing connections. There is a test clip provision
located on the top of each pole that allows connection with standard spring clip test leads.
FT Test Switches:
The ITI FT Test Switches and Test Plugs provide a safe, simple, immediate and reliable method to isolate equipment and measure
system current and voltage during field testing and commissioning.
RT Rack Mount Test Switches:
RT Switch assemblies for rack and switchboard mounting permit convenient isolation of switchboard relays, meters and
instruments. RT racks allow quick and easy multi-circuit testing by conventional test methods and for faster installation into
switchgear.
FT Test Switch:
Built with a maximum of ten individual poles, of potential,
current, and current shorting switch units
Switches can be assembled in a variety of different
arrangements to match customer requirements
FT Test plugs are used in conjunction with the FT Switches
to enable easy measurement, calibration, verification or
maintenance of relays, meters and instruments
UL / cUL E101598
Protection:
With the cover in place, a meter type seal can be placed
through either of the cover studs of the FT Switch to
prevent unauthorized access
Standard black cover mounts only when all switches are
in the closed position
A clear cover is available that can be installed with the
switchblades in the open or closed position
RT Rack Mount Test Switches:
RT Switches accommodate three FT switches mounted
on a 19” wide steel mounting panel (Brushed aluminum
available)
Provides up to 30 terminals with three FT combinations
Color and finish can be customized
Optional rack heights for label applications
Each panel is supplied with the hardware to mount the RT
assembly to the 19” rack enclosure
The RT assembly will support an FT style test plug
Full-length clear cover is standard. Full length black cover,
individual clear covers, and individual black covers are
available
UL / cUL E101598
Protection:
Once the full-length clear cover on the RT switch is
installed, it prohibits access to some of the rack mounting
screws
Individual clear covers offer additional protection
consistent with common testing procedures to ensure
only correct switch is exposed during testing
