ABB 1YMB710727M1611 HV CEF type Fuse link high-voltage backup fuses

ABB 1YMB710727M1611 belongs to the HV CEF type high voltage current limiting backup fuse, with the following features and related information:

Basic information: It belongs to the CEF type fuse, with a rated voltage range of 3.6/7.2 - 36kV, and the rated current of this specific model is 50A.

Design and standards: It is designed and tested in accordance with IEC60282-1 standard, and the dimensions are consistent with DIN43625, ensuring the standardization and versatility of the product.

Product features:

Excellent performance: It has the characteristics of low minimum breaking current, low power consumption, and low arc voltage, which can effectively protect the circuit while reducing the adverse effects on the circuit system. Its high breaking capacity and high current limiting characteristics can significantly reduce the short-circuit current, extend the insulation life of the equipment, and ensure the safety of the equipment during short-circuit faults.

Versatile: The integrated striker and temperature control unit (TCU) prevent overheating at the installation site, and the internal arc initiation is controlled by the overload point design. It has excellent temperature performance and can effectively cope with various overload and overheating conditions.

Widely applicable: There is a single fuse version for indoor and outdoor use, suitable for a variety of environmental conditions, and the unified voltage rating also makes the application more flexible. In addition, the narrow resistance tolerance is conducive to better fuse synchronization in three-phase networks, and the key data of the fuse is engraved on the outer surface for long-term identification and maintenance.

Application scenarios: It is mainly used to protect distribution transformers, cables, overhead lines and other equipment from the thermal and dynamic effects of short-circuit currents. It is suitable for indoor/outdoor and oil-immersed installations and other scenarios, providing reliable protection for the safe and stable operation of power systems.
