ABB CMF 7.2KV/100A CMF type Fuse link high-voltage backup fuses

ABB CMF 7.2KV/100A fuse is a high-voltage current-limiting backup fuse. The following is a detailed introduction:

Basic information:

Model meaning: "CMF" represents the fuse type, which is used for motor circuit protection; "7.2KV" is the rated voltage, indicating that the fuse is suitable for 7.2 kilovolt power systems; "100A" is the rated current, which means that the current allowed to pass through the fuse when it is working normally for a long time is 100 amperes.

Design standard: Designed and type tested in accordance with IEC60282-1 standard, it ensures that the product quality and performance meet international specifications and can work well with other electrical equipment that meets relevant standards.

Product size: Length is about 442mm and diameter is 87mm.

Performance characteristics:

Protection characteristics: Designed to protect motor circuits from the thermal and dynamic effects of short-circuit currents. Through special design, it can withstand typical cyclic loads in motor applications, and with its 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 both indoor and outdoor environments and can adapt to a variety of harsh conditions.

Functional configuration: Equipped with an 80N (medium) striker, when the melt melts, the striker will move and give obvious indications, so that the operation and maintenance personnel can find out whether the fuse is activated in time. A temperature control unit can also be optionally equipped to provide additional thermal stress protection for fuses in small spaces to prevent failures caused by overheating.

Application scenarios: Mainly used in power systems with a rated voltage of 7.2kV, in various motor drive equipment in the industrial field, such as factory fans, water pump motors, mine ventilator motors, and various production equipment that require motor drive, it plays a short-circuit protection role for the motor circuit, ensuring the safe and stable operation of the motor and the entire power system.

Market price: On some industrial product sales platforms, its price may be around 1,600 yuan/unit, but the price may vary depending on factors such as purchase quantity, procurement channels, and market supply and demand.
