Title:
EARTH LEAKAGE BREAKER
Document Type and Number:
Japanese Patent JP3275441
Kind Code:
B2
Abstract:
PURPOSE: To increase insulating effect of a primary conductor and improve reliability of an earth leakage breaker by installing a primary conductor insulating part in side face insulating parts which cover both side faces of a zero-phase current transformer.
CONSTITUTION: A zero-phase current transformer 10 is inserted between both side insulating parts 17a, 17b. A primary conductor 9s is inserted in hole insulating parts 18a, 18b which are set in the hole 10a of the transformer 10 and while right and left primary conductors 9R, 9T being inserted in the hole 10a in both sides of the insulating parts 18a, 18b, the insulating parts 17a, 17b are fixed by snaps by both stopping parts 20a, 20b. The primary insulator 16 composed in this way is fixed in a case 1.
