更できるという効果もある。 As described above, according to the present invention, the outer shell 1 is composed of the base 2, the cover 3, and the sub-base 4 fixed to the back surface of the base 2, and the zero-phase current transformer 11 is at least partially inside the sub-base 4. At the same time, the holding part 17 of the connecting plate 15, one end of which is fixed to the end of the coil 16 of the overcurrent tripping electromagnet 8, is housed so as to be located within the sub-base 4. The clamping part 17 and the movable contact 6
A flexible conductor 18 that passes through the zero-phase current transformer 11
Since the back side of the circuit breaker is insulated at the sub-base 4, the back side of the base 2 can be largely opened, and the overcurrent tripping electromagnet 8 and the flexible conductor 18 can be connected. Since the clamping part 17 of the connection plate 15 fixed to the coil 16 protrudes from the back surface of the base 2, the overcurrent tripping electromagnet 8
After attaching the movable contactor 6 and the movable contactor 6 to the base 2, the flexible conductor 18 can be connected to the holding part 17 of the connecting plate 15 very easily, so the structure is simple, the assembly is very easy, and the manufacturing cost is low. effective. In addition, when it is used by incorporating it into a switchboard, etc., and it is desirable to change the height of the shield disconnector to match the height with other shield disconnectors, switches, etc., the height of the sub-base 4 can be changed. Another advantage is that it can be easily changed.
