Automatic fuses with switch protect the cables and conductors against the over current and short-circuit. When a fault occurs (over current), automatic fuses are used in front of them to prevent the conductor cross-sections which have been established constitute a fire hazard to the environment and insulation material. Thus, electrical circuits are protected in houses and industry. Automatic fuses with switch provide to convenience of opening and closing with their switches in the connected circuits. However, in case of failure, tripping schemes which is independent of the switch prevents to switch on as long as it continues to fail.
Type B automatic fuses with switch makes the process of cutting off following the current rises in between of 3-5 times of nominal operating current, logarithmically.
Type C automatic fuses with switch makes the process of cutting off following the current rises in between of 5-10 times of nominal operating current, logarithmically.
Type D automatic fuses with switch makes the process of cutting off following the current rises in between of 10-20 times of nominal operating current, logarithmically.
1 pole auto fuses with switch can make process of cutting off and circuit protection on a single wire or cable.
2 poles auto fuses with switch can make the process of cutting off and circuit protection on a single phase and single neutral wire or cable.
3 poles auto fuses with switch can make the process of cutting off and circuit protection on belonging of the three phase conductor or cable.
4 poles auto fuses with switch can make the process of cutting off and circuit protection on conductor which constitutes 3 phase and neutral line and carry unbalanced load or cable.
