To enable to display a leakage action by an electric signal, attaching to an earth leakage braker of a standard specification afterwards a leakage action output switch as an internal accessory device of a cassette type.
An earth leakage breaker mounts an overcurrent protection and ground fault protection function component of a breaker including a leakage detection circuit and a leakage tripping device 1 in a main body housing of a single structure, consisting of a case 6a, a cover 6b, and a top cover 6c. A recess 6b-3 for storing various internal accessory devices on both sides of an operation handle 7 is formed on the cover 6b. An earth leakage operation output switch 5 is a cassetted internal accessory device that indicates earth leakage trip operation of the breaker electrically, mechanically links with the earth leakage tripping device 1 to the recess with free detachment in an inserted condition, and makes to operate the earth leakage operation output switch at the time of the earth leakage trip operation of the breaker, so that electrical signals can be output.
