PURPOSE:To facilitate a mounting work by forming a groove for a mounting pawl separately different from the groove of an equipment for a movable pawl for clamping a rail. CONSTITUTION:A rail 1 is mounted on an electric equipment 2 by a stationary pawl 22 of the equipment 2 and a movable pawl 3 to be inserted into the groove 26 of the equipment 2. A groove 25 is also formed above the groove 26. When the mounting pawl of a breaker for a JEM standard type wiring is mounted in the groove 25, the breaker can be mounted on the equipment 2 without removing the rail 1 to facilitate its mounting work.
