ABB 1YMB710721M1611 HV CEF type Fuse link high-voltage backup fuses

ABB 1YMB710721M1611 belongs to HV CEF type fuse, which is a high-voltage current limiting backup fuse. The specific information is as follows:

Basic parameters: The rated voltage range of HV CEF type fuse is 3.6/7.2 - 36kV, and the rated current of this model is 25A.

Design and standards: Designed and tested in accordance with IEC60282-1 standard, the size is consistent with DIN43625, ensuring the standardization and versatility of the product, and can be well adapted to electrical equipment that meets relevant standards.

Product features:

Excellent performance: With the characteristics of low minimum breaking current, it can respond to small fault currents and cut off the circuit in time to protect the equipment; low power consumption makes the fuse generate less heat when working normally, reducing energy loss, which is conducive to extending the life of itself and surrounding equipment; low arc voltage can reduce the arc energy when cutting off the circuit and reduce the damage to the insulation of the equipment; high breaking capacity and high current limiting characteristics can quickly limit the short-circuit current size in the event of a short-circuit fault, reducing its thermal and dynamic impact on the equipment.

Various functions: integrated striker and temperature control unit (TCU). The striker device gives obvious indications when the fuse is actuated, which is convenient for operation and maintenance personnel to find faults in time; TCU monitors the fuse temperature in real time to prevent overheating at the installation location, controls the internal arc initiation through the overload point design, and has excellent temperature performance to avoid malfunction or damage caused by overheating.

Widely applicable: There is a single fuse version for both indoor and outdoor use, and the standard version includes outdoor sealing, which is suitable for harsh environmental conditions; the unified voltage rating makes the application more flexible and can adapt to power systems of different voltage levels; the narrow resistance tolerance is conducive to better fuse synchronization in the three-phase network, ensuring consistent protection performance of the three-phase circuit and reducing the risk of failure caused by three-phase imbalance; the key data of the fuse is engraved on the outer surface for long-term identification and maintenance, which facilitates operation and maintenance personnel to obtain information for installation, commissioning and troubleshooting.
