HH15(QSA) series isolating switch fuse groupDetailed product description：

Application of HH15 (QSA) series isolating switch fuse group
It is mainly used in distribution circuits and motor circuits with high short-circuit currents as a manual, infrequently operated main switch or main switch, especially suitable for installation in higher-level drawer type low-voltage complete sets of equipment. The double throw switch is used for infrequent connection and disconnection of dual electrical circuits.





Structural features:
The switch adopts a fully enclosed structure to ensure improved operational reliability and stable performance; Featuring a unique rolling insertion contact system. Each phase has two sets of contact systems with double break points, which can be connected in series or parallel to meet the requirements of circuits with different current sizes and different working categories. The contact system allows current to pass through several rollers, resulting in a significant reduction in the electric reaction force experienced by each roller. During the movement, the contact between the roller and the stationary contact has both rolling and sliding friction, which can effectively avoid welding. The operating mechanism has an energy storage spring, so the movement speed of the moving contact group is independent of the magnitude of the operating force and the operating speed. The actuator consists of a handle mounted on the panel, a drive coupling that engages with the handle, an extension shaft, a shaft coupling, and a drive shaft. Extension and shaft and shaft and shaft coupling joints are only used when the drive shaft is not long enough. The depth of installation of switches in a set of cabinets can be considered according to the needs of the installation of various electrical components in a complete set, with a considerable range of activities.

The technical data of HH15 (QSA) series isolating switch fuse group complies with IEC947-3 and GB14048.3
