ABB 1YMB710725M1611 HV CEF type Fuse link high-voltage backup fuses

ABB 1YMB710725M1611 belongs to HV CEF type fuse, which is a high voltage current limiting backup fuse. Its related information is as follows:

Basic parameters: It is a specific model of CEF type fuse. The rated voltage range of CEF type fuse is 3.6/7.2 - 36kV, and the rated current of this model is 40A.

Design and standards: It is designed and tested according to IEC60282-1 standard, and the size is consistent with DIN43625, which ensures the international versatility and standardization of the product, and can better adapt to various electrical equipment that meet relevant standards.

Product features:

Excellent performance: With the characteristics of low minimum breaking current, it can respond to smaller fault currents, cut off the circuit in time and protect the equipment; the low power consumption characteristic makes the fuse generate less heat during normal operation, reducing energy loss, and also helping to extend the service life of itself and surrounding equipment; low arc voltage can reduce the arc energy generated when the circuit is cut off, reducing the damage to the insulation of the equipment; high breaking capacity and high current limiting characteristics can quickly limit the size of the short-circuit current when a short-circuit fault occurs, significantly reducing the thermal and dynamic impact of the short-circuit current on the equipment, and effectively protecting distribution transformers, cables, overhead lines and other equipment.

Various functions: integrated with striker and temperature control unit (TCU). The striker device can give obvious indications when the fuse is actuated, so that the operation and maintenance personnel can find faults in time; TCU can monitor the temperature of the fuse in real time to prevent overheating at the installation location, and control the internal arc initiation through the overload point design, so that the fuse has excellent temperature performance, which can avoid false operation or damage caused by overheating.

Widely applicable: There is a single fuse version for both indoor and outdoor use. The standard version includes outdoor sealing, which is suitable for harsh environmental conditions and can work stably whether in indoor switch cabinets or on outdoor poles; 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 quickly obtain relevant information of the fuse and carry out correct installation, commissioning and troubleshooting.
