Document Type and Number:
Japanese Patent JP2016015289
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide an electromagnetic tripping device of an earth leakage breaker including a leakage display button with a small number of components.SOLUTION: The electromagnetic tripping device of an earth leakage breaker includes: a trip lever 6 that transmits an action of a plunger 5 to an interruption mechanism; a magnet case 4 that houses an electromagnet device 3; a coil spring 2 that activates a display action of a leakage display button 1a; a coil spring 7 for returning to the original position the trip lever 6 moved in conjunction with restoring the plunger 5 that performed a pull-in operation; and a reset arm 8 for resetting a display action of the leakage display button 1a in conjunction with an off operation of an operation handle 21 for switching a cable way. The leakage display button 1a is formed at an apex of an advancing/retreating component 1 that advances and retreats from an inside of the magnet case 4 and performs display/non-display of a leakage occurrence by an advancing/retreating action of the advancing/retreating component 1. The advancing/retreating component 1 is engaged with the trip lever 6 in both states of being advanced and retreated and mutual positions are regulated.
