main product features:
1. the interrupter of the circuit breaker has a single break design and a simple and reasonable structure with high technology. it meets the requirements of iec 62271-1 and iec 62271-100.
2. strong breaking ability, long contact life (rated number of short-circuit breaking is up to 20 times) and long maintenance period.
3. except for the bushing unit which is packaged separately, the interrupter unit, hydraulic operation mechanism, current transformer and other components of the whole-pole circuit breaker are packaged as a whole unit, which does not require on-site docking and adjustment and is convenient for installation.
