Product Description

Product Description

The use of high-performance vacuum interrupter and epoxy solid sealing pole comprehensively improves the electrical life and capacitive breaking ability of the product, making the product more safe and reliable. The newly upgraded vacuum circuit breaker has superior performance, with full capacity breaking times up to 100 times, electrical service life up to 50,000 times, back-to-back capacitor bank breaking current up to 800A, and using voltage and current double refining process. The innovative visual design of overtravel can visualize the degree of wear of the vacuum interrupter contacts. These designs have effectively improved the safety, reliability and electrical performance of the product.
