PROBLEM TO BE SOLVED: To easily mount a terminal cover in a simple structure and at a low cost by guiding a lead wire to the side of a terminal. SOLUTION: On the outer wall 53 of a mainbody cover 35 to cover the mainbody base of a breaker mainbody 31 of a master breaker 24, a groove 55 open to the back side is integrally formed. A lead wire 44 is arranged in the groove 55 and guided to the lower side of a terminal 41. A terminal cover 32 to cover the terminal 41 is mounted on the breaker mainbody 31 by elastically engaging the engagement pawl of the terminal cover 32 with the engagement support 50 of the mainbody cover 35. An operating tool is inserted from the window of the terminal cover 32 and the engagement pawl is pushed to remove the terminal cover 32. |
