HH15 (QSA) Series Switch Disconnector Fuse
Purpose
Mainly used in distribution circuits and motor circuits, as a main switch or master switch for manual infrequent operation.
Characteristics
Suitable for circuits with AC 50Hz, rated voltage up to 660V, and agreed heating current up to 1250A.
Adopting a fully enclosed structure with a quick operating mechanism to ensure the safety of operators and equipment.
The contact system is unique and can effectively prevent the occurrence of contact welding points, withstanding large short-circuit currents.
The operating handle can be installed on the switch cabinet door and interlocked with the cabinet door to prevent accidental operation.
Advantages
High breaking capacity, reaching 660V, AC-23 category.
The contact has a long lifespan and is equipped with an arc reducing device.
Strong isolation function, able to safely replace fuse links and inspect and repair power distribution equipment.
Standardized and serialized design, convenient for selection and use.
Is designed for distribution circuits and motor circuits with high short-circuit currents, ensuring safety and reliability at critical moments.
As a manual and infrequently operated main switch, it is particularly suitable for installation in high-rise drawer-type low-voltage complete equipment, which is convenient for maintenance and operation.
The design of the double-investment switch enables it to efficiently connect and disconnect dual circuits, meet diverse power needs, and meet the performance standards of IEC947-3, ensuring the international recognition and safety of the product.
