Vacuum Circuit Breaker

Zhejiang Sangao Electric Co., Ltd. is an advanced enterprise born and developed with the rapid development of China's reform and opening up. It mainly produces vacuum circuit breakers and other products. The company has 120 employees, including 20 experienced professional and technical personnel, and a registered capital of RMB 81.68 million. The company strictly implements ISO9001, ISO14001 and OHSMS18001 management, laying a solid foundation for core products such as vacuum circuit breakers.

Vacuum circuit breakers (VCB) are one of Sangao's flagship products and are widely favored by the market. Vacuum circuit breakers are indispensable equipment in power systems. They use vacuum as an arc extinguishing medium to safely cut off current in overvoltage, undervoltage or short circuit conditions. When the circuit trips and the contacts separate, the arc is quickly extinguished in a vacuum environment. Sangao offers a full range of indoor and outdoor vacuum circuit breakers.

The SANGAO vacuum circuit breaker is designed by our professional team. Its key components include static contact, moving contact, vacuum interrupter and reliable operating mechanism. Compared with traditional technology, what are the advantages of the Sangao vacuum circuit breaker? It has maintenance free, long service life, strong environmental adaptability, etc. I believe it will meet your requirements.
