CT19IV type spring operated mechanismDetailed product description：

CT19-IV type spring operated mechanism can be used to operate 35KV vacuum circuit breakers and SF6 vacuum circuit breakers with equivalent closing power. Use of low oil circuit breakers, etc The product performance meets the requirements of GB1984-89 AC high-voltage circuit breaker standard and product technical conditions
The CT19-IV spring operated mechanism has two types of energy storage: electric motor energy storage and manual energy storage. There are two types of opening operation: closing electromagnet and manual button. There are three types of opening operation: opening electromagnet, overcurrent trip electromagnet, and manual button.
This institution is based on CT19, widely absorbing the advantages of similar products at home and abroad, and combining with the actual situation to overcome the shortcomings of current similar products. It is designed with the latest concept This mechanism adopts a front upper output, reducing many mechanical losses. Compared with other similar products, it has the advantages of low noise, smooth movement, compact structure, small volume, light manual energy storage, and long service life.
