Abstract

The invention relates to a structure of an electronic molded case circuit breaker. The structure comprises a base, a middle cover, a control unit, a control panel, a visual panel and a face cover, wherein the middle cover is installed on the base, an inner concave cavity for accommodating the control unit is formed in the middle of the middle cover, the control unit is mounted in the inner concavecavity, the control panel is mounted at the upper part of the control unit, and the visual panel is mounted on the control panel; the face cover is mounted on the middle cover and fastened with the base. The control unit is placed in the inner concave cavity of the middle cover and is isolated from an operating system of the base, so that the function of isolating protection of the control unit can be achieved, damage to components of the control unit caused by breaking high currents can be prevented, the control unit is easy to assemble and maintain, and knob positioning is more accurate.

Description

technical field [0001] The invention relates to a circuit breaker, in particular to an electronic molded case circuit breaker structure. Background technique [0002] The existing electronic circuit breaker control unit is placed between the operating system and the middle cover, and is generally installed on the base or transformer support through the controller support. All components of traditional electronic circuit breakers, including the control unit, are sealed in a plastic case. When a large breaking current is encountered, the metal material will generate gas and metal particles under the arc energy, and the gas will be discharged through the air hole during the process. Under the action of strong air flow, metal particles splash on the control panel of the control unit and destroy the insulation of the control unit. At the same time, the control unit of the electronic circuit breaker with traditional structure cannot be repaired due to the compact internal structur...
