ABB CMF 12KV/200A fuse is a high-voltage current-limiting backup fuse for motor circuit protection. Here is a detailed introduction:
Basic information:
Model specification: The full model may be similar to 1YMB761239M4813, where "CMF" indicates the fuse type, "12KV" is the rated voltage, "200A" is the rated current, the size is 442/87mm (length/diameter), and there is no TCU (temperature control unit).
Design standard: Designed and type-tested in accordance with IEC60282-1 standard, it can ensure that the product quality and performance meet international specifications and can work well with other electrical equipment that meets relevant standards.
Performance characteristics:
Protection characteristics: Designed to protect motor circuits from the thermal and dynamic effects of short-circuit currents. Its special design can withstand the typical cyclic loads in motor applications, and through robust design and compliance with the latest IEC standards, it can ensure continuous protection and reliable operation.
Environmental adaptability: The standard version includes an outdoor sealing design, which is suitable for indoor and outdoor environments. It can work stably under harsh conditions and adapt to a variety of different working environments.
Functional configuration: Equipped with an 80N (medium) striker, the striker will move when the melt melts, giving an obvious indication, so that the operation and maintenance personnel can find out whether the fuse is activated in time. At the same time, a temperature control unit can be optionally equipped to provide additional thermal stress protection for fuses in small spaces to prevent failures due to overheating.
Application scenario: Mainly used in power systems with a rated voltage of 12kV to protect motor circuits. In various motor drive equipment in the industrial field, such as large motors in factories, hoist motors in mines, crane motors in ports, etc., it can play its role in short-circuit protection of motors to ensure the safe and stable operation of motors and the entire power system.
