Basic Info.
Product Description
ZN12 Indoor AC HV Vacuum Circuit breaker
Product introduction:
Base on the technology of Germany Siemens, ZN12-40.5 Indoor AC HV Vacuum Circuit breaker is developed. It
is an indoor switchgear used for the power system with 40.5 kV rated voltage, three-phase AC 50 Hz. The circuit
breaker is able to be operated frequently and break the false short circuit current for many times. It is not only
suitable for trolley switchgear but for fixed switchgear to protect and control the apparatus in industrial and
mining field, enterprises, power plant and substation.
Features:
High breaking capability, long endurance. Adopting integration spring operating mechanism, it is simple in
structure, small in size and reliable in performance. The main galvanic circle and operating mechanism is in
front and back arrangement and they are flexible and easily mounted. It is simple and reliable with mechanical
and electrical interlocking. It adopts plateau design and it has good insulation level.
