CHM1HU Series 800V-1140V Photovoltaic High Voltage Plastic Case Circuit Breaker

12kV outdoor high-voltage disconnectors and vacuum circuit breakers are widely used in medium-voltage power distribution systems, primarily providing control, isolation, and protection. They are particularly well-suited for substations, industrial and mining enterprises, and rural power grid upgrades.

Product Advantages:
High insulation performance: Utilizes high-voltage composite or ceramic insulators, suitable for harsh outdoor environments.
Safety isolation: Features a clearly visible break, ensuring safe maintenance.
Modular structure: Easy installation and easy integration with vacuum circuit breakers, lightning arresters, and other devices.
Multiple operation modes: Supports manual, electric, and remote control to meet the needs of smart grid access.
Low maintenance: Vacuum arc extinguishing design ensures long mechanical life and is suitable for frequent operation.

Typical Applications:
Rural distribution line segmentation; Industrial user line isolation; Boundary switches in urban distribution automation systems; Small substation inlet and outlet protection equipment.

Combining high-reliability operation with safe isolation, this series of 12kV outdoor high-voltage disconnectors and vacuum circuit breakers is an indispensable component of modern power distribution systems, contributing to efficient, safe, and intelligent power grid operation.
