​Low voltage electrical equipment covers air circuit breakers, molded case circuit breakers, miniature circuit breakers and surge protective devices. Intelligent air circuit breakers offer measurement and communication functions, while new energy high voltage models are designed for direct current and high voltage scenarios with specific arc extinguishing and insulation. Compact and high current fixed air circuit breakers suit cabinets with limited space or concentrated loads.

​Disconnect switches and earthing switches are important components for ensuring maintenance safety in distribution systems. Indoor disconnect switches cover 12kV, 24kV and 40.5kV levels, mainly with a rated current of 630A. Some models include an earthing switch, allowing isolation and earthing to be completed in one operating sequence. High altitude disconnect switches are adjusted in terms of insulation distance and materials for low pressure and large temperature differences, suitable for higher elevation areas.

Vacuum circuit breakers are widely used in medium voltage distribution systems, and pole-mounted configurations are particularly suitable for overhead line networks. Outdoor pole-mounted vacuum circuit breakers are available at 12kV, 24kV and 40.5kV levels for different distribution applications.

Indoor vacuum circuit breakers are used across medium voltage distribution systems, with product configurations covering 12kV, 24kV and 40.5kV applications. Different voltage levels, mounting structures and operating mechanisms allow the equipment to be matched with various switchgear cabinets, substations and industrial distribution systems.
