ABB 1YMB710718M1611 HV CEF type Fuse link high-voltage backup fuses

ABB 1YMB710718M1611 belongs to HV CEF type high voltage current limiting backup fuse. The following is its relevant information:

Basic parameters: The rated voltage range of HV CEF type fuse is usually 3.6/7.2 - 36kV. Although there is no public information that clearly gives the rated current of 1YMB710718M1611, according to the specifications of CEF type fuse, its rated current may be in the range of 6 - 200A.

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

Various functions: integrated with the 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, control 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, suitable for a variety of 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 three-phase networks, ensuring consistent protection performance of three-phase circuits 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, and it is convenient for operation and maintenance personnel to quickly obtain relevant information about the fuse and perform correct installation, commissioning and troubleshooting.

Application scenarios: 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 installation and other scenarios, providing reliable protection for the safe and stable operation of power systems.
