PURPOSE:To make it easy to have the breaker mentioned in the title subjected to a dedicated brazing machine for improving brazing operativity between both ends of an excitation coil and a shunt and a terminal as well as eliminating the necessity of bending both ends of the excitation coil for simplifying manufacture of the exciting coil by a method wherein electrode directions are made equal. CONSTITUTION:Both ends 21A, 21B of an excitation coil of an electromagnetic device 8 are formed in a direction of a terminal 17 plate while the terminal 27 and a shunt 16 are brazed to both coil ends 21A, 21B so as to make electrode directions at respective brazing operations equal. Thus the breaker can be easily subjected to a brazing machine and brazing operativity between both ends 21A, 21B of the excitation coil and the shunt 26 and the terminal 27 is improved as well as bending both ends 21A, 21B of the excitation coil is not necessary to simplify the manufacture of the excitation coil. |
