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. 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.
