ZN85‑40.5 Indoor High‑Voltage AC Vacuum Circuit Breaker
Features
‑ The circuit breaker adopts an overall layout with vacuum interrupter on the top and operating mechanism at the bottom, convenient for commissioning. ‑ Adopts air‑solid composite insulation, featuring compact design and light weight. ‑ Compatible with vacuum interrupters from Cutler‑Hammer and domestic ZMD vacuum interrupters. Both types employ axial‑magnetic‑field arc‑extinguishing technology, with low chopping current and excellent asymmetrical breaking performance. ‑ Simple spring operating mechanism, with mechanical endurance of 10,000 operations. ‑ Lead‑screw driving mechanism, with good efficiency, balance and self‑locking performance.
