Abstract:
PURPOSE: To reduce a cost of a cover of a four pore circuit breaker and reduce a storage space.
CONSTITUTION: A cover 3 of a case 1 of a four pole circuit breaker is constituted by combining a cover 4 for a three pole circuit breaker with a cover 5 for one pole newly formed. The cover 5 is small and its mold cost is cheap compared with the conventional constitution in which the whole body is integrally molded, and cost is reduced since molding cycle is short.
