Metal Enclosed Circuit Breaker Switchgear

Metal enclosed circuit breaker switchgear is a fully enclosed medium voltage distribution system with a vacuum circuit breaker as the core component. It features independent compartments for circuit breakers, busbars, and cables, ensuring safe and reliable power distribution for industrial and commercial applications.

With 9 years of experience in high voltage switchgear manufacturing, our factory operates a 2,000㎡ standardized production facility equipped with sheet metal processing and electrical testing equipment. Our 40–50 skilled technicians independently complete cabinet fabrication, assembly, and inspection. We support OEM/ODM customization based on customer drawings or samples, with a minimum order quantity of 1 set.

Each metal enclosed circuit breaker switchgear undergoes 100% electrical inspection before shipment, including insulation, circuit operation, and withstand voltage tests. We support third-party inspection and provide a 1-year warranty. During international transportation, if the cabinet body or breaker components are damaged, we will evaluate the issue and provide original replacement parts according to the actual situation.

The fully enclosed metal structure effectively prevents arc exposure and improves operation safety. It is widely used in photovoltaic plants, industrial power systems, substations, and prefabricated transformer stations, with long-term export experience in Southeast Asia, the Middle East, and other overseas markets.

Standard products support 30% advance payment with balance before shipment. Customized metal enclosed circuit breaker switchgear requires a 50% deposit before production, with the balance paid before delivery. Large-volume customers can apply for better pricing and priority production schedules. Production progress, including cabinet assembly, breaker adjustment, and electrical testing, can be updated through photos and videos.
