FT Specifications
Rating
The standard FT switch is rated at 600 volts and 30 Amps. The
Switch meets or exceeds all requirements of ANSI / IEEE Standard
C37.90 and is UL and cUL recognized.
Mounting
FT Switches are designed for semi-flush mounting on the front of
switchboard panels, facilitating inspection and accessibility.
Drilling Plan - Inches
FT Switch Construction
The base of the FT Switch is made of black electrical grade plastic
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
ample space between terminals.
Cover
FT Switches come with a black opaque cover or a clear see-through
cover. Switch covers provide a tough insulated enclosure for the
switch and are made from plastic material. The clear cover affords
the user the option of leaving switch handles in the open position
and replacing the cover while maintaining the provision for a meter
type seal when some or all switch handles are in the open position.
This feature allows the user to service electrical equipment while still
complying with OSHA lockout/tag-out procedures. The clear cover
can be ordered separately for retrofit to existing FT Switches. RT
racks come standard with a full length clear cover and can be sealed
with a meter seal.
Fasteners
Captive fasteners are made of molded plastic with a threaded brass
insert for easy cover installation and removal.
Switch Poles
FT Switches are available in configuration of 1 to a maximum of
10 individual poles or switch units. Each pole identified by letter (A
thru J), which is visible along the top of the base from left to right.
The individual switch units are of knife blade type. There are three
different types of switch units available: potential, current , and
current shorting.
Switch Handles
Switch handles are made of a molded plastic insulating material
typically black in color. Red handles can be supplied by replacing
the “P” with “T” for potential handles and replacing “C” with “R” for
current handles. Additional colors are available upon request.
Each handle has a dovetail indentation to hold a circuit identification
label (by others). Knife blade switches can be operated independently
or ganged together with a horizontal interlocking bar (see page 4).
A hole runs through the middle of each switch handle to allow
insertion of interlocking bars. 2 to 10 switch handles can be
mechanically tied together.
Terminals
Connection terminals are located at the rear of the switch and can
be either screw or stud type. Terminals are numbered 1 thru 20 for
easy identification. Each pair of numbered terminals is associated
with a matching pole designated by a letter on the front of the switch.
