Problems solved by technology

However, in the existing modular molded case circuit breakers, the installation and disassembly of the functional components need to remove the upper cover first, and then the opening and closing monitoring mechanism or electromagnetic shunt components can be installed. The operation is not only cumbersome, but also Easy to damage internal components during disassembly

Abstract

The invention discloses a moulded case circuit breaker comprising a base and an upper cover. A wiring terminal assembly, a contact system and an operating mechanism are arranged in the base; the operating mechanism comprises an operating handle; the top of the upper cover is provided with an operating panel; and the operating panel of the upper cover is provided with at least one mounting openingand a cover plate used for covering the mounting opening. In the invention, a switching on / off monitoring device and an electromagnetic shunt release device can be selectively installed or detached without detaching the upper cover.

Description

technical field [0001] The invention belongs to the technical field of low-voltage switches, and in particular relates to a molded case circuit breaker. Background technique [0002] The existing molded case circuit breakers all include a base and an upper cover, and the base is provided with a terminal assembly, a contact system, an operating mechanism and a common tripping mechanism; Electromagnetic shunt trip mechanism for remote operation. [0003] Generally speaking, different users have different requirements for the internal structure of circuit breakers. In order to reduce costs and increase the convenience of selection, modular molded case circuit breakers have become a development trend now. [0004] Modular molded case circuit breakers generally make separate components such as electromagnetic shunt tripping mechanism, circuit board, opening and closing monitoring mechanism according to their respective functions, and reserve installation positions in the base. ...
