Description

Technical Field

[0002] A circuit breaker is a switch device that can close, carry and interrupt the current under normal circuit conditions, and can close, carry and interrupt the current under abnormal circuit conditions within a specified time. Circuit breakers are divided into high-voltage circuit breakers and low-voltage circuit breakers according to their scope of use. The boundary between high and low voltage is relatively vague, and those above 3kV are generally called high-voltage electrical appliances.

[0003] The existing technology has the following problems:

[0004] However, during the closing process of existing pre-energy release circuit breaker products, the end of the handle is a cylinder, which causes slippage due to the small contact area when manually closing, resulting in slower closing. At the same time, the handle feels heavy when pushed, and products with a heavy feel have a greater impact on the mechanical life of the product.
