BUSSMANN FNQ-R-3-2/10-R1 Fuse, 3.2 A, Non-Indicating, 200 kAIC, 600 V

Working Mechanism:

• Inside, a lower-melting-point element awaits to interrupt the circuit.
• When current surpasses its limit, the melting element heats up due to increased resistance.
• Excess heat melts the element, breaking the circuit to halt current flow.
• This interruption prevents damage to downstream equipment and wiring.
• Once blown, the user must replace the fuse for continued circuit protection.

Features:

• This fuse has an AC voltage rating of 600VAC and a current rating of 3.2A.
• It features a cartridge body style for structural rigidity and durability.
• This fuse comes without an indicator for seamless operations.
• It offers a holder based mounting for ease of installation and a clip mechanism for convenient termination.
• This industrial power fuse has an interrupt rating of 200kA for effective current interruption.

Frequently Asked Questions:

Q. How do I install this industrial power fuse?

A.

• Open the fuse holder or disconnect the circuit from the power source.
• If present, remove the old or blown fuse from the holder.
• Check the contacts for any signs of damage, corrosion or debris.
• Insert the new Bussmann FNQ-R-3-2/10-R1 fuse into the holder.
• Ensure the fuse is properly seated and secure in the holder.
• Close the fuse holder securely.
• Restore power to the circuit to test the new fuse's functionality.
• Observe the circuit to ensure proper operation without any issues.

Q. What factors should I consider while choosing the right industrial power fuse?

A.

• Match the fuse's current rating with the circuit's requirements.
• Ensure that the fuse can handle the circuit's voltage level.
• Account for temperature, humidity and contaminants.
• Determine the needed level of equipment and circuit protection.
• Verify if the fuse can safely interrupt the maximum fault current.
• Choose a fuse with a suitable response time for the circuit.
• Ensure that the fuse fits the available space and is easy to install.
• Select a fuse type that suits your specific application (e.g., motor protection).
• Check for compliance with relevant industry standards.

Q. What is the difference between Bussmann FNQ-R Series fuses and KTK-R fuses?

A.

• Bussmann FNQ-R Series fuses typically offer higher current ratings for larger circuits.
• Both series have comparable voltage ratings suitable for industrial applications.
• KTK-R fuses are smaller and fit compact spaces and FNQ-R fuses are larger for higher currents.
• FNQ-R fuses suit industrial machinery, whereas KTK-R Series fuses are common in control panels and electronics.
• FNQ-R fuses often have higher interrupting capacities for high short-circuit currents.
• FNQ-R Series fuses offer enhanced motor protection and the KTK-R fuses provide reliable electronics protection.
