Abstract:
To provide a circuit breaker capable of easily performing an insulation resistance measurement test even in a state of connecting a load wiring to a rapid-connecting terminal.SOLUTION: Support walls 5 and 5 stood in a vertical direction to an inclination surface is provided along left and right side edges of a front surface of a main body case 4, and a notch 31 is provided at a position that is the support wall 5 on the right side and is a right side of each insertion hole 16. Therefore, when executing an insulation resistance measurement test or the like, even if a load wiring is connected to terminals L1 to L3 and the position of each of the insertion holes 16, 16 ... is in a state where it is difficult to view directly, the position of each insertion hole 16 can be easily gripped as a mark of each of the notches 31, 31 .... In addition, when a tip of a measurement terminal via the notch 31 is moved to the left side, the tip of the measurement terminal can be positioned front of each insertion hole 16.
