Abstract

The invention discloses a subminiature molded case circuit breaker, which comprises a bottom shell, a moving contact mechanism, a fixed contact, an arc extinguishing chamber and a traction rod. The subminiature molded case circuit breaker is characterized in that the traction rod, a traction rod bracket and an armature of a traditional molded case circuit breaker are integrally laminated into an integral structure, so that the size is reduced; a moving contact, the fixed contact and the arc extinguishing chamber of the subminiature molded case circuit breaker within the finite volume can be lengthened; the current limiting capacity of the molded case circuit breaker is improved; the breaking capacity of the subminiature molded case circuit breaker reaches the breaking level of the similar molded case circuit breaker; the working performance is more stable and reliable than that of a miniature circuit breaker while the size is greatly reduced; the subminiature molded case circuit breaker can be arranged on a guide rail for use like the miniature circuit breaker; and the subminiature molded case circuit breaker can be widely applied to building electricity.

Description

technical field [0001] The invention relates to a low-voltage electrical appliance, in particular to an ultra-small molded case circuit breaker. Background technique [0002] Molded case circuit breaker is a commonly used power distribution protection device. It has the functions of on-off, overload and short-circuit protection for load power supply, and is widely used in power distribution systems. Compared with miniature circuit breakers of the same specification, molded case circuit breakers have the advantages of large breaking current, strong overload capacity and stable working performance. The molded case circuit breaker has the advantages of large breaking current, strong overload capacity and stable working performance, and the miniature circuit breaker is small in size and suitable for rail installation. The molded case circuit breaker has a broad market prospect. Contents of the invention [0003] The purpose of the present invention is to change the disadvanta...
