Indoor High Voltage Vacuum Circuit Breaker

Our Indoor High Voltage Vacuum Circuit Breaker serves as the heart of metal-clad switchgear. This unit covers voltage levels from 10kV to 40.5kV. The ZN85-40.5 model is our primary offering in this series. It uses a withdrawable trolley design. This structure lets you push the breaker in and out of the switchgear easily. This feature makes daily inspection and maintenance much simpler. When the breaker sits in test or isolated position, both primary and secondary circuits disconnect. This gives operators a visible safety gap they can see clearly. We have extensive experience in switchgear assembly and matching. We know that breaker performance depends on proper mechanical fit and electrical connections. Our integrated production covers sheet metal processing and electrical assembly. This approach lets us control product matching from the start. We ensure every breaker connects perfectly with your switchgear. Our factory produces both the breaker and the enclosure. This gives us full control over fit and tolerances.

Every Indoor High Voltage Vacuum Circuit Breaker undergoes full testing at our facility. We run mechanical endurance tests on each unit. We check opening and closing speeds against design targets. We measure main circuit resistance to confirm good connections. All tests ensure the breaker performs to its rated specifications. Our 12-month warranty covers the product from delivery. We also provide spare parts support for ongoing maintenance. The breaker is designed for KYN series metal-clad switchgear. This compatibility covers most common switchgear models in use today. The product's withdrawable design simplifies replacement and retrofitting. You can upgrade old breakers without changing the whole switchgear. Our technical team provides selection and installation guidance. We answer your questions promptly to keep your project on schedule. Choose our Indoor High Voltage Vacuum Circuit Breaker for a durable and reliable switchgear component.
