Model meaning
The ZN63 high-voltage circuit breaker (often also known as the VS1 circuit breaker, VS1 being its most common model designation) is an indoor-installed medium-voltage circuit breaker employing vacuum arc-extinguishing technology. It is widely used in three-phase AC 50Hz power systems with rated voltages from 3.6kV to 12kV, serving as a protective and control device for power equipment, and is one of the core switching devices in modern substations and industrial and mining enterprise power distribution systems.
