Home / Products / Isolating switch / Load-Break Switch
This product is a high-voltage load-break switch rated at 10kV, 400A, which can be combined with a current-limiting fuse to form a load-break switch–fuse combination unit, mainly used for the control and protection of transformers and lines within distribution systems, with the capability to switch load current.
Features:
Compact structure and simple operation, with reliable and rapid switching action; when combined with a fuse, it can achieve rapid clearance of short-circuit faults, protecting transformers and line equipment, while also offering good insulation performance and mechanical service life.
Applications:
Widely used in box-type substations, pole-mounted transformers, and various terminal distribution equipment, serving as a combination switch for transformer protection and line control, and is an economical and practical protection component in medium- and low-voltage distribution systems.
