Indoor high voltage vacuum circuit breaker

Outline

TZN12 (68) -12 series vacuum circuit breakers are indoor high voltage switchgear with rated voltage of 12KV three-phase AC of 50Hz. It is the product that introducing of German Siemens technology. The operating mechanism of the circuit breaker is spring energy storage type. It can be operated by AC or DC, and can also be operated manually. It is suitable for the control or protection of transmission and distribution systems like power plants and substations, especially in places where important loads are cut off and frequently changed.

TZN12 (68)-40.5 vacuum circuit breaker can match the main switch of TKYN-40.5, TKYN1-35, and TGBC-35 series switchgear. The circuit breaker is mounted on the handcart in the switchgear as a movable unit. Meanwhile, the circuit breaker can also be installed in the TXGN-40.5 switchgear for fixed installation. The circuit breaker body is integrated with the switch: special spring energy storage operating mechanism, and can be operated by AC, DC energy storage or manual operation.
