The rated voltage of ZN12-40.5 type vacuum circuit breaker is 40.5KV, and the rated current is 630A. It is suitable for three-phase AC 50Hz power systems. This product is designed with various phase-to-phase distances such as 350mm, 400mm, and 460mm, and can be used in conjunction with different types of switchgears.
Its circuit breaker can be used in fixed cabinet XGN17-40.5, and also in JYN1-40.5 and KY10-40.5 cabinets. The arc extinguishing chamber of ZN12-40.5 type vacuum circuit breaker has a porcelain structure and adopts a longitudinal magnetic field contact design. This design makes the diffusion arc current generated during interruption uniform on the contacts, avoiding local melting. The circuit breaker adopts special contact materials, which endows it with high breaking capacity and long electrical life, and also has the characteristics of low arc energy voltage (20-200V) and low current chopping value (4-15A). The ZN12-40.5 type circuit breaker adopts a spring energy storage operating mechanism. Its operating mechanism models include type DYT-1, and it can also be equipped with type 3AF spring operating mechanism. This mechanism adopts a dual-purpose motor, supports AC or DC energy storage operation, and also has a manual operation function.
