GENERL INFORMTION BOUT LOD BREK 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 IEC- EN 60947- and VDE-0660 standards, CE certificate and C 2 class. Due to this feature they are used at C 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 ) 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. 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. 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 ). 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. - dditional fuse protection shields are used for better isolation and protection in the switch fuses. - rc separators are used for arc extinguishing between contacts which occur during closing or breaking process. Locking with padlock 0 position Rolling contact system (250,, 60) Pic-2 Pic-1 Opening-closing mechanism and control handle : 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. /2
GENERL INFORMTION BOUT THE LOD BREK 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. In this way this system provides clear and precise touching at every opening and closed. Especially contact destruction is prevented by rolling contact system. rc 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. ny damage to contact is prevented in the rolling contact. ccessories : Following accessories are available, -Cage type connection terminals - Terminal protective covers (Pic-4) - Neutral link available - uxiliary 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.
