Molded case circuit breaker with quick installation structure

Abstract

The invention provides a molded case circuit breaker with a rapid installation structure, and relates to the technical field of molded case circuit breakers, the molded case circuit breaker comprises a molded case circuit breaker body, the front surface of the molded case circuit breaker body is provided with an operation handle, the rear surface of the molded case circuit breaker body is provided with two supporting plates, and a clamping block is installed in a clamping groove through a fixing assembly. According to the molded case circuit breaker, the first sliding plate is pulled to enable the side plate to move backwards, and when the first sliding plate moves, the second sliding plate and the first sliding plate can be driven to move in the opposite directions, so that the molded case circuit breaker is prevented from being damaged, and the service life of the molded case circuit breaker is prolonged. The clamping block is arranged in the clamping groove, at the moment, the pulling plate is loosened, the first sliding plate can be reset through the elasticity of the first spring and the second spring, the fixing column can be reset, the molded case circuit breaker body is installed on the supporting plate, and the device is easy and convenient to install and disassemble.

Description

technical field [0001] The invention relates to the technical field of molded case circuit breakers, in particular to a molded case circuit breaker with a quick installation structure. Background technique [0002] The molded case circuit breaker can automatically cut off the current after the current exceeds the trip setting. Molded case refers to the use of plastic insulators as the casing of the device to isolate conductors and grounded metal parts. Molded case circuit breakers typically contain thermal magnetic trip units, while larger models have solid state trip sensors. Its trip unit is divided into: thermal magnetic trip and electronic trip, such as patent application number, CN201510601423.3 A molded case circuit breaker provided with a mechanical interlock device, including: the first molded case circuit breaker and The second molded case circuit breaker is equipped with a handle for controlling the closing and opening of the circuit breaker. The mechanical inter...
