Title:
CIRCUIT BREAKER
Document Type and Number:
Japanese Patent JP3183395
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To form a distribution panel conjugate circuit breaker, which has the double-pole structure at a width dimension by the conventional one pole, by integrally forming a switching unit of a double-pole one-element and double- pole two-element and an excess current tripping element within the cross dimension of an agreed shape.
SOLUTION: In a wiring circuit breaker 1, a double-pole switching unit and a one-pole or a double-pole excessive current tripping element are housed in a main body 2 at 25mm of width, which is determined by an agreed shape dimension, and a switching handle 3 is projected from a front surface of the main body 2, and power side terminals 4, 11 and load side terminals 5, 12 are arranged in both ends of the circuit breaker 1. Multiple wiring circuit breaker 1 are arranged inside of a lamp distribution panel and divides a main line from a main wiring circuit breaker. In this case, a double-pole (switching part) one-element (excess current tripping element) is used for a circuit at 100V, and a conventional block terminal for neutral pole is unnecessary. A double-pole two-element is used for a circuit at 200V, and parallel arrangement of two elements is unnecessary.
