CT10-A type spring operated mechanismDetailed product description：

The CT10-A type spring operating mechanism is an improved and reinforced version of the original CT10 type spring operating mechanism, which greatly enhances its mechanical strength and service life.

The CT10-A spring operated mechanism can be used to operate various 35KV circuit breakers and circuit breakers with equivalent closing power, and its performance meets the requirements of "GB1984-89" "AC High Voltage Circuit Breakers" and the "Technical Conditions" of this product. The main indicators meet or exceed the IEC standards.
There are two energy storage methods for the closing spring of the mechanism: electric motor energy storage and manual energy storage. The closing operation includes two types: closing electromagnet operation and manual button operation; There are two types of opening operations: electromagnetic release and manual button operation; There are two types of electromagnetic release devices: shunt release devices and instantaneous overcurrent release devices.
