Switch-Disconnector-Fuse Switch-Disconnector Type FN
Switch-Disconnector-Fuse Switch-Disconnector
Type FN
Features of FN series :• Compact design saves space• Electrodynamic Compensation• Quad break Contact System• Full AC - 23 A rating for the Complete range• Highest fused Short Circuit Capacity• Quick make / Quickbreak / Positive break• Clear ON / OFF indicator• Separate arcing / Current carrying zone• High clearance & Creepages• Separate bridge for each pole• Maximum ground Clearance• Phase barrier & Terminal Shroud as a
Standard accessory• Fuse stationary & Isolated from both sides• Direct access to mounting & terminal screws• Generous terminal capacity • Replaceable contacts for enhanced life• Suitable for vertical & horizontal orientation• Wide range of Spares & Accessories• Handle coupling as per IS 8623
The handle coupling has the
following user-friendly features.
Easy fixing of handle on panel door
by two screws.
Door interlock for safety of operating
personnel when switch is ‘ON’. The
interlock can be defeated if required.
Built-in padlocking arrangement to
lock the unit in either ‘ON’ or ‘OFF’
position.
The handle coupling can take a
mismatch or ±3mm in all directions.
High making & breaking capacity
Due to Quad break construction.High Electrical & Mechanical life.
Clear ON / OFF indication is
provided on the switch (by a red pointer)
Built-in neutral :
Switch-Disconnector-Fuse
consist of an integral neutral,
making the units suitable for
3 phase, 4 - wire application.
FN 32 / 63 has switched
neutral while higher ratings
have isolable neutral.
Mechanism :
This mechanism is front operated quick-make / quick-break and independent of speed of operation.
SALIENT FEATURES
1
Compact construction :
To ensure light weight
low operating torque
switch which saves panel
space.
Easy to maintain contacts.Phase barriers :Interphase barriers are provided to eliminate
the possibility of
interphase short circuit.
The Switch-Disconnector-Fuse
units can be mounted at
any angle in a vertical plane.
Fuses are isolated from both
sides. This offers safety to operating
personnel while replacing fuses.
Fuses remain
stationery during
switching operation.
Large Ground Clearance
to eliminate possibility of
phase-ground flash over.
Large terminals to accommodate
Aluminium bus bars.
The terminals can be shrouded for
protection against phase-phase short
circuit through an external conducting
path and also for protection against
accidental human contact to live
terminals.
Terminal shrouds, to protect against
phase-phase short circuit
Contact System : Contact system is QUAD BREAK. There are no. of
parallel moving contacts per pole per break. Hence,better Arc Quenching & more electrical life of contacts.
Each pole has separate bridge, carrying the moving
contacts, achieving a high order of interphase separation & avoiding phase-phase flash over.
SDF Interior in Sheet Steel Enclosure :
Complete range of S-D-F is also available in
attractive powder coated sheet steel enclosures.FN 32 / 63 in sheet steel enclosure comes
fitted with gland plate.

lrrespective of the switch orientation
(vertical or horizontal), operation in any of
the four quadrants is possible by selecting
right handle coupling (Refer table on next
page)
1 NO + 1 NC auxiliary contact is available
as an accessory. This can be suitably
wired in the control circuit. Rated operational current l (AC - 15) - 4 Ae
Rated operational voltage U - 415 e
Moving contacts are available for ranges
FN 100 to FN 800. One set of moving
contact spare contains, spring, guide &
moving contact.
Complete front housing assembly is
available from FN 100 to FN 800.
Wide range of spares & accessories are available
for Switch-Disconnector-Fuse units type FN.
In FN 32 / 63 Switched-Neutral pole is an integral
part of the Switch-Disconnector-Fuse. For higher
ratings, a double break, site-fitted switched
neutral pole can be provided. This is operated by
the main mechanism.
The terminals can be shrouded for protection
against phase-short circuit through an external
conducting path and against accidental human
contact with live terminals.
Two Switch-Disconnector-Fuse units can be
interlocked by mechanical interlock kit. After
interlocking, the following three positions are
possible.
3) Both SDFUs in OFF position Hence two
mechanically interlocked SDFUs can be
used as a change over switch.
Switch-Disconnector-Fuse units can be locked
on OFF position with help of castell interlock.
Castell interlock can also be used to interlock two
S-D-F units. (Different variety of locks are
available)
