ABB CMF 12KV/100A CMF type Fuse link high-voltage backup fuses

ABB CMF 12KV/100A 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 1YMB531030M0002, where "CMF" indicates the fuse type, "12KV" is the rated voltage, "100A" is the rated current, and the size is 442mm (length) × 87mm (diameter).

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. Continuous protection and reliable operation are guaranteed through robust design and compliance with the latest IEC standards.

Environmental adaptability: The standard version includes an outdoor sealed design, suitable for indoor and outdoor environments, can work stably under harsh conditions, and adapt to a variety of different working environments.

Functional configuration: Equipped with an 80N (medium) striker, when the fuse melts, the striker will move, giving an obvious indication, so that the operation and maintenance personnel can find out whether the fuse is operating in time. At the same time, a temperature control unit can be optionally equipped to provide additional thermal stress protection for the fuse in a small space to prevent failure 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 a role in short-circuit protection of motors to ensure the safe and stable operation of motors and the entire power system.
