GENERAL INFORMATION ABOUT LOAD BREAK SWITCHES & SWITCH FUSES
General characteristics :
The Federal Load Break Switches & Switch Fuses have
been designed to provide a compact, instantly openingclosed with rolling or friction contact. They have a breaking
feature from same phase and four different points and are
high performance devices. Load break switches are
manufactured with or without fuses according to the IECEN 60947-3 and VDE-0660 standards, CE certificate and
AC 23 class. Due to this feature they are used at AC and
DC systems and motor circuit.
Various combinations and types with high amperes which
are not shown in this catalogue are manufactured accordig
to special orders.
General features :
• High breaking capacity,
• High electrical and mechanical endurance,
• Rolling contact system (except for 160 A) capable of selfcleaning,
• Double breaking on each phase,
• Modern technology and compact design,
• Quick making and breaking operation independent of
manuel operation,
• Small dimension,
•Case made of thermoset material, non absorbing and
flame-heat resistant,
• Capable of mounting to front or rear side of panel cover.
160A switches are manufactured with friction and high value
switches are manufactured with using rolling contact. Friction
and rolling contact systems provide clear and precise
touching at every opening and closing of switch. Passing
resistance and loss of energy among the contacts are limited
to minimum with respect as a special spring. Current is
broken from same phase and at four different points in the
switch (except 160 A). This feature builds up current breaking
capacity of switch and fuses separated from the circuit at
two points. (Pic-1)
Safety :
- Off “0” position both fuse terminals will not be alive so the
fuses can be changed, safely.
- On “I” position the handle will be locked mechanically, so
the panel cannot be opened while energized.
- Off “0” position the handle can be blocked out with a
padlock so that it may prevent any unauthorized personnel
to energize the panel.
- The isolation distance between the phases is rather wide
to prevent arc jumping.
- Additional fuse protection shields are used for better
isolation and protection in the switch fuses.
- Arc separators are used for arc extinguishing between
contacts which occur during closing or breaking process.

Contacts :
Load break switches & switch fuses consist of contact
system with constant contact which placed moulded case.
Breaking energy is divided between contacts with this
system. Combustion in contact is kept minimum due to
energy is dividing between contacts and arc extinguisher
elements in the breaking chamber. Getting small combustion
extends the life of contacts.

Opening-closing mechanism and control handle :
Pic-1
3/2
Opening-closing mechanism has been provided to operate
the poles altogether and very rapidly. Speed of opening
and closing is independent from hand moving. Control
handle is passing type. The handle extention is necessary
for all cases supplied in the length, than it is cut by the
customer at the desired length. The position of switch can
be seen by means of indicating plate and control handle.
Switching angle for ON/OFF operation is 90 degrees.

GENERAL INFORMATION ABOUT THE LOAD BREAK SWITCHES & SWITCH FUSES
Inside construction :
Current is broken from the four separate points in a rolling
contact system. This way the breaking capacity is increased
and when the circuit breaker is in open position, fuses are
seperated from the circuit completely.
- Opening closing position are not depending on hand
actuated.
- High speed opening-closing can be done thanks to the
springs in mechanism.
Frictional system is applied at type of 160 A. In this way this
system provides clear and precise touching at every opening
and closed. Especially contact destruction is prevented by
rolling contact system. Arc extinguishers are used for arc
extinguishing between contacts which occur during making
or breaking process.
mechanical resistance in a compact design. Connection
bars are plated with silver. Capable of mounting to front or
rearside of panel cover.
Operating principle :
By means of a special sling rolling contact system, moving
contacts are mechanically connected to the operating handle
to ensure a positive ON/OFF action and a forced operation
of contacts. Any damage to contact is prevented in the
rolling contact.
Accessories :
Following accessories are available,
-Cage type connection terminals
- Terminal protective covers (Pic-4)
- Neutral link available
- Auxiliary conctact block 1NO + 1 NC for remote
indication of switch status.
- Special interlock and padlock system.
Note: Terminal cover prevent to contact of switch fuse
cable connection terminal with hand. This feature provides
safe the insulation according to CE certificate.
