Primarily used as a manual, unattended main switch or master switch in power distribution circuits with high short-circuit currents and low power factors.
The HH15(QSA)/QP/QA series disconnectors integrate isolation, control, and protection functions, effectively isolating power and enabling safe maintenance. Built-in high-performance fuses provide reliable current limiting, effectively reducing the impact of short-circuit currents on equipment.
The compact design features a double- or multi-break contact system with wide contact spacing, ensuring standard clearance and creepage distances, enhancing electrical safety. A clear disconnect position indicator helps maintenance personnel confirm the isolation status.
Flexible mounting options allow for front- or rear-panel installation to meet the requirements of various cabinet structures. Suitable for power isolation and short-circuit protection in industrial and mining enterprises, building power plants, commercial buildings, and various types of complete power distribution equipment.
