摘要： PROBLEM TO BE SOLVED: To effectively cool arc and lead it to a discharge port so as to enhance the cutoff property to a large current, by arranging an arch extinguisher in the position opposed to the rotation locus of a mobile contact carrier on the side of an arch discharge port. SOLUTION: An arch-extinguishing chamber is arranged so that a fixed contact may oppose a mobile contact at the bottom, and also it is made along the locus of the mobile insulating stand 7 whose aperture 8 opens and closes on the side, facing the rotation center of a mobile contact carrier, of a casing 2, and the mobile contact carrier 7 is passed into the aperture 8. The casing 2 restrains arc generated between contacts from flowing out to the side of an opening/closing mechanism or the side of an operation lever. Moreover, at the mounting part of the fixed contact carrier, only the fixed contact 6a and the arc runner 9 annexed to it are exposed within the casing 2, and other sections are covered with an insulating board.

摘要： PURPOSE:To increase safety by allowing a sensitivity current frequency characteristic of a rapid and highly sensitive leakage circuit breaker to fall below the threshold value stipulated by IEC479-2. CONSTITUTION:When a leakage current having a frequency higher than a commercial one, a rapid and highly sensitive leakage circuit breaker ELB4 cuts off its circuit since the value of the leakage current exceeds the sensitivity current value of the breaker ELB4. Medium sensitive leakage circuit breakers ELB1, ELB2 which are cascade-connected above another rapid and highly sensitive leakage circuit breaker ELB3 do not cut off their own circuits at that high frequency leakage current since the leakage current value does not reach the value of the sensitivity current of the breakers ELB1, ELB2 which has sharply risen. Therefore, a leakage current which exceeds the threshold value of IEC479-2 that is dangerous to human body is cut off and this grounding failure does not spread to the other devices as protection coordination is taken. Consequently, safety is increased.
