Voltage and Current: Rated voltage up to 12kV, rated current 63-315A.

Features: Specially designed for cyclic loads in motor applications, standard version includes outdoor sealing for harsh environmental conditions, and is also equipped with a temperature control unit to provide additional thermal stress protection for equipment in small spaces.

ABB HV CMF type Fuse link is a high-voltage current-limiting backup fuse, mainly used to protect motor circuits from the thermal and dynamic effects of short-circuit currents. The following is a brief introduction:

Design features: Designed and tested in accordance with IEC60282-1 standard, the special design enables it to withstand typical cyclic loads in motor applications, ensuring long life and trouble-free operation.

Performance advantages: It has the advantages of low minimum breaking current, low power consumption, low arc voltage, high breaking capacity and high current limiting characteristics. The low power consumption makes it particularly suitable for compact switchgear or contactor rooms; it can withstand the impact current of the motor, quickly limit the current in the event of a short-circuit fault, and reduce damage to the equipment.

Functional configuration: Equipped with an 80N (medium) striker, the striker action gives an indication when the fuse melts. There is also a temperature control unit to provide additional thermal stress protection for fuses in small spaces to prevent overheating.

Use environment: The standard version includes an outdoor sealed design, suitable for indoor and outdoor environments, and can work reliably under harsh conditions.

Rated parameters: The rated voltage can reach up to 12kV, and the rated current range is 63A - 315A.
