Eaton Bussmann TCF20RN Time Delay Fuse

Eaton Bussmann TCF20RN High Speed Fuse

summary

The Eaton Bussmann series Class CF fuse, model TCF, is a time delayed, dual element current limiting cubic fuse. This 20A fuse does not have an indication function, but it can quickly cut off the current when the circuit is overloaded or short circuited, thus protecting the circuit from damage. The following is a detailed introduction to this fuse.

Product Features

• Rated current: 20A, suitable for circuit protection with medium current demand.
  
• Voltage level: Suitable for circuits with 300 Vdc or lower, as well as 600 Vac or lower.
• Interruption Capability: The fuse has an interruption capability of 100 kA at 300 Vdc and 300 kA at 600 Vac, which means it can safely interrupt very high short-circuit currents.
• Type of fuse: Class CF, which is a type of fuse with time delay characteristics, suitable for applications with high surge loads.
• Fuse Structure: Dual element current limiting design, combined with the current limiting function of Class J fuses, providing fast and controlled current interruption.
• Installation Method: Clip lock design provides a fast and secure installation method.
• Shell material: Melamine tube, a heat-resistant and arc resistant material, provides excellent insulation and protection performance.
  

Application Fields

The Eaton Bussmann series Class CF fuses are widely used in applications that require fast response and moderate current carrying capacity, such as.

• Industrial control system: protects motors, transformers, and switchgear.
• Power Conversion and Distribution: Provide overload and short circuit protection in power conversion equipment, such as uninterruptible power supplies (UPS) and inverters.
• Semiconductor Protection: Due to its high-speed melting characteristics, it is particularly suitable for protecting semiconductor devices such as diodes, thyristors, and MOSFETs.

Technical parameters

• Rated current: 20A, meeting the needs of most medium current industrial applications.
• Interruption capability: It has an interruption capability of 100 kA at 300 Vdc and 300 kA at 600 Vac, providing strong short-circuit protection.
• Fuse level: Class CF, providing dual protection functions of time delay and current limitation.

Installation and use

When installing Eaton Bussmann series Class CF fuses, the following guidelines should be followed.

• Ensure that the rated voltage and current of the fuse match the requirements of the circuit.
• Use Clip lock installation method to ensure that the fuse is firmly fixed in place.
  
• Before installation, check all connections to ensure good contact and avoid looseness or corrosion.
  
• During use, regularly check the status of the fuse and replace the blown fuse in a timely manner.

The Eaton Bussmann series Class CF fuses provide strong protection for various industrial and power applications with their outstanding performance and reliability. Its dual element design and time delay characteristics make it an ideal choice for handling high surge loads, while its high breaking capacity ensures safety under extreme short-circuit conditions.
