ZN105-12/T5000-63 Vacuum Circuit Breaker for Generator

The ZN105-12/T5000-63 vacuum circuit breaker for generator was developed on the basis of the launched ZN65A-12/4000-63 and ZN105-12/6300-80 products as well as the German Siemens's 3AF technology.

This large-capacity circuit breaker integrating large rated current (5,000A) and high breaking capacity (63kA) is applicable to three-phase AC systems with the rated voltage of 12kV and the rated frequency of 50Hz. It is suitable to work as the control and protection switch in power plants and substations.

Features
1. As a generator circuit breaker, our product complies with the GB/T14824-1993 "General Technical Conditions for the Generator Breaker" standard and the DL/T427-1997 "Ordering Technical Conditions for the Indoor Type Generator Breaker" standard.

2. This vacuum circuit breaker for generator adopts the integrated spring energy storage type operating mechanism which can be operated by AC, DC or hand.

3. With advanced and reasonable design, our generator breaker has simple structure, strong breaking ability, long mechanical life, and complete operating functions. It poses no risk of explosion during operation.

4. The air insulation ensures excellent insulation performance and facilitates heat dissipation, enabling the vacuum circuit breaker to fully satisfy the requirement of using in indoor areas with the filthy condition reaching Grade II.
