Product Details:

Bussmann 550FMM specialty fuse is used in heavy machinery and equipment, where electrical systems demand robust protection against overcurrent conditions. It is ideal for safeguarding high-energy circuits, preventing damage to sensitive components and ensuring operational safety. This fast blow fuse offers reliable protection where high current loads are essential, mitigating potential risks and maintaining system integrity.

Features:

  • This high speed semiconductor fuse features cartridge blade body for structural rigidity and durability.
  • It comes with a current rating of 550A and voltage rating of 500VAC.
  • This fast blow fuse offers stud mounting for ease of installation.
  • It has bolt down style termination without any indicator for operational safety.

Frequently Asked Questions:

Q. How do I identify a faulty specialty fuse?

A.

  • Look for physical damage like burns, discoloration or a visibly broken element within the fuse.
  • Use a multimeter to check for continuity across the fuse terminals. A reading of infinite resistance indicates a blown fuse.
  • Measure the voltage drop across the fuse when the circuit is active, a significant drop might suggest a faulty fuse.
  • If the circuit protected by the fuse is malfunctioning or not working at all, it could be due to a blown fuse.
  • Modern systems may display fault codes or indicators when a fuse is faulty.
  • Replace the fuse with a new one of the same specifications and see if the circuit functions properly.

Q. Does Raptor Supplies offer other specialty fuses with higher current ratings?

A. Yes, customers looking for specialty fuses with higher current ratings can opt for Bussmann 630FMM and 700FMM specialty fuses having current ratings of 630A and 700A, respectively.

Q. What factors should I consider while choosing this high speed semiconductor specialty fuse?

A.

  • Ensure that the fuse's current rating is suitable for your circuit's maximum expected current.
  • Match the fuse's voltage rating with your circuit's voltage level.
  • Confirm that the fuse is designed for your specific application (e.g., high-power machinery).
  • Choose the appropriate blow speed (fast blow) for rapid overcurrent protection.
  • Check if the fuse's dimensions fit within your equipment's available space.
  • Ensure that the fuse can operate within your system's temperature range.
  • Opt for reputable brands for reliable performance.
  • Verify that the fuse complies with relevant safety standards for your industry.
