Yirong 12kV vacuum circuit breaker is a key part for indoor high-voltage power. It’s made to help you adjust power flow and keep circuits safe in all kinds of settings. The design is compact and all in one. It insulates well, runs smooth, and doesn’t take up much space. That’s great for tight indoor spots.
What makes this breaker stand out? It breaks reliably, handles different loads with ease, uses long-lasting parts, and is easy to use every day. All that means less work later on — saving you both time and money on upkeep. You’ll find it in factory workshops, indoor substations, city power projects, and commercial building power systems.
We’ve been making and upgrading 12kV vacuum circuit breaker for ten years now. Every unit goes through standard processes and 100% tested in every process. You can count on every breaker to be stable and dependable when you receive it.
One more thing is, we can provide customized sizes and spare parts according to customers’ requests.We have our own factory, years of experience, and solid aftersales support, we offer global buyers good value for money and one-stop service.
Types of 12KV Vacuum Circuit Breaker
Saves Energy
We’ve improved our 12kV vacuum circuit breaker with a low-power operating mechanism and a high-efficiency vacuum interrupter. That means it runs without using much power. Save energy in your distribution system. It meets energy-saving and standards. It’s also quiet — no disturbance to the surroundings. Great for city grids, residential areas, and factory floors where peace and quiet matter.
Low Failure Rate, Easy to Maintain
This 12kV vacuum circuit breaker has a simple design and a few parts that wear out. So you don’t need to maintain it often. The parts are designed in a modular way and are easy to change. It doesn’t take much time for checks, maintenance, or changing parts. We keep a tight grip on quality and use solid manufacturing processes. That’s why this breaker rarely fails. It runs steadily for a long time, helps you save on maintenance costs, and cuts down your work time.
- Ambient temperature: It works normally between -25°C and +40°C.
- Altitude: Normally, it’s suitable for areas below 1,000 meters. If you use it in high-altitude areas, you’ll need reinforced insulation.
- Environmental conditions: It should be installed in places without corrosive gases, flammable or explosive materials, heavy dust, and no long-term condensation or moisture.
- Make sure the installation is firm and the grounding is reliable.
- The primary wiring must be tight and according to the torque standards.
- The secondary wiring must follow the relevant standards.
- Keep the insulation components clean and no damage.
- For draw-out models, check if the cabinet size and rails match properly.
- Rated current: Common specifications are 630A, 1250A, 1600A, 2000A.
- Short-circuit breaking capacity: You usually have three choices: 20kA, 25kA, or 31.5kA. Choose the one that is suitable for the grid’s short-circuit capacity.
