Yirong focuses on manufacturing and supplying fixed circuit breakers. Our fixed circuit breakers are reliable, high-performance control and protection devices for power systems. With a fixed installation structure, they run steadily, have a long service life, and fully meet standard voltage and specification requirements.
In various application scenarios, they guarantee stable current interruption, effective fault isolation, and safe power distribution.
We strictly implement quality control, and provide customizable designs, fast delivery, and cost-effective solutions—this is why our products are widely used in indoor power grids, industrial facilities, high-rise buildings, substations, and renewable energy projects.
With over 15 years of industry experience, our own production facilities, and a professional team of more than 20 electrical engineers, Yirong is dedicated to providing global customers with consistent product quality, on-time delivery, and comprehensive end-to-end services.
Types of Fixed Circuit Breaker
Customization That Fits Your Exact Needs
We can customize our fixed circuit breakers to fit your project just right. Just tell us your specs and voltage needs—we do 10kV, 12kV, 11kV, 35kV, plus low, medium and high voltage. We’ve also got different sizes to fit your installation space. If your site is tight or has special layout needs, our team will tweak the size so it installs easily and runs smoothly. This personalized service saves you time and installation costs, and ensures the breaker runs steadily in your power system.
Top Quality, No Cutting Corners
Quality’s our top priority—we have a dedicated QC team watching every step of making our fixed circuit breakers. Every part of the production line gets full testing; we never cut corners. First, we check all raw materials really well, so only the best go into each breaker. That’s how we make sure they last long and work reliably. From the first raw material check to the final test before we send it out, we pay attention to every little detail. So every breaker we send you meets all quality standards and runs well for years.
Fixed: The main body is installed permanently. Any maintenance work requires power cut-off and cabinet cover removal. It is compact in structure, cost-effective and occupies little space.
Draw-out: It can be pulled out and pushed back, which facilitates maintenance work and ensures high safety. However, it is more costly and is mainly used in critical medium and high-voltage circuits.
First, vertical or horizontal installation must follow the manufacturer’s guidelines—most models require vertical installation. Second, the switchgear cabinet should be well-ventilated, and the installation environment must be free of corrosive gases, dust, and flammable or explosive materials. Finally, the wiring must be fastened securely, insulating components should be clean and undamaged, and the grounding system must be reliable.
Normal operating temperature range: -15°C to +40°C.
