When football sparks summer passion and the roar of tens of thousands of fans fills the stadium, flickering lights, lagging live streams, and power failures are completely unacceptable. Your venue’s power grid needs a steadfast "high-voltage goalkeeper".
The PEOPLE ZN73-S High-Voltage Vacuum Circuit Breaker brings World Cup-level reliability to the table, standing firm as the guardian of your 10kV power lifeline. Whether powering full-stadium large screens, broadcast systems, HVAC and elevators, or night lighting and VAR systems, the ZN73-S operates like a top-tier defensive midfielder: steady, rugged, and error-free, delivering every kilowatt of power with pinpoint precision.
The ZN73-S comes in two structural designs to suit diverse application scenarios:
▍Embedded pole version: Fully enclosed construction ensures completely maintenance-free operation.
▍Insulating cylinder version: Combines cost-effectiveness with excellent heat dissipation performance.
Much like a championship team’s starting XI and rotation squad, the two configurations deliver precisely matched protection solutions for different power distribution environments.
With a maximum rated short-circuit breaking current of 31.5kA, a rated peak withstand current of 100kA, 30 cycles of rated short-circuit breaking capacity, and a 10,000-cycle mechanical service life, the ZN73-S completes precise interruption within milliseconds of a short-circuit fault. Just like an elite defender’s game-saving goal-line tackle—fast, accurate, and decisive—it immediately stops "foul play" (electrical faults) before they can "score" a catastrophe, safeguarding both personnel and equipment safety.
Standard anti-pumping and interlocking functions guarantee reliable tripping during faults, preventing fault escalation and cascading failures while reducing operation and maintenance costs. Mirroring the precise tactical execution of a title-winning team, it enables automatic fault identification, coordinated response, and zero-fault performance, ensuring uninterrupted operation throughout consecutive matches and overnight live broadcast schedules.
Fully compatible with KYN28 switchgear cabinets and various armored mid-mounted switchgear, with rated current options of 630A and 1250A, the ZN73-S is widely applied in commercial real estate construction and general industrial projects. It delivers maximum reliability, adapts to all types of power distribution layouts, supports quick on-site assembly, and provides continuous, stable power protection day and night.
