CHARACTERISTICS 1. The vacuum arc extinguishing chamber uses longitudinal magnetic field arc extinguishing technology, which has the characteristics of long electric life and high reliability. 2. The imported silicone rubber/epoxy resin for outdoor use and the present APG vacuum injection technology are adopted. 3. Anti-ultraviolet, moistureproof, anti-corrosion, with the advantages of preventing surface discharge, good hydrophobicity and high mechanical strength. 4. Using simple and reliable spring operating mechanism, it has the advantages of small size and light weight. 5. high voltage vacuum circuit breaker can be equipped with isolation switch and three-phase linkage. It has visible breaks when the isolation switch is switched off. It also has anti-mistake interlock between the isolation switch and the circuit breaker body. It can be equipped with arrester strut insulators. Operational sequence When operating the disconnector, the first step is to confirm that the circuit breaker should be in the open state. Use the insulated tie rod hook to fasten the closing pull ring or the opening pull ring of the operating handle of the isolation closure, pull down slightly, drive the spindle to rotate, open or close the isolation switch. When the spindle rotates the dead point position of the compression spring, a certain tension is maintained so that the blade can be reliably closed or opened to a safe isolation position.

Our featured products automatic transfer switch, circuit breaker, contactor, pilot light,relay, SPD, etc. with solid quality and considerable price and could equip them with enclosure. Circuit Breaker DZ47 is an automatically operated electrical switch designed to protect an electrical circuit from damage caused by overload or short circuit. Its basic function is to detect a fault condition and, by interrupting continuity, to immediately discontinue electrical flow. When a current is interrupted, the arc must be contained, cooled, and extinguished in a controlled way. So that the gap between the contacts can again withstand the voltage in the circuit. Electric ratings:  a. AC: up to 63A, AC230/400V, AC50/60Hz; b. DC: up to 63A, DC110V/1P, DC125V/2P; Application: for protection of circuits from over-load and short-circuit; and for infrequent making and breaking of circuits under normal operation conditions, as well; Standard: IEC/EN 60898.
