Bussmann FWA-50A21F fuse is used in electrical settings for interrupting the fault current during overloads and short circuit conditions. This fast-blow fuse senses sensitive changes in the current flow and is occasionally coupled with an indicating fuse block or cover to enhance visibility and diagnostics.
Features:
- It features a single-element design for rapid protection in medium voltage circuits.
- This high-speed fuse has a cylindrical body ensuring a seamless and secure installation.
- It has interrupt ratings of 100kA at 150VAC and 100kA at 150VDC for enhanced circuit protection against high current incidents.
- This fast-blow semiconductor fuse is made of melamine for structural rigidity and electrical insulation.
Compatible Accessories:
- Bussmann FP-3 Fuse Puller: This electrical fuse puller offers an extended reach to access confined spaces where fuses might be out of hand's reach. It maintains a safe distance between hands and wires, ensuring insulation against electrical shock hazards.
Frequently Asked Questions:
Q. What ae the factors to consider while selecting an appropriate Bussmann fuse?
A.
- Regular operational current
- Operating voltage
- Ambient temperature conditions
- Initial inrush currents
- Peak fault current
- Required duration for the fuse to open
Q. How can you check a fuse without a fuse tester?
A.
- Use wire strippers to remove around an inch of insulation from both wire ends.
- Connect one wire end to a fuse terminal and the other to the opposite terminal on the fuse.
- If the fuse is functional, the connected light bulb will illuminate.
- Conversely, if the fuse is malfunctioning, the light bulb will not light up.
Q. What is the main difference between fast-blow and slow-blow fuses?
A. The main difference lies in their response time to overcurrent events. Fast-blow fuses react very quickly to overcurrent conditions, breaking the circuit almost instantly. Slow-blow fuses, on the other hand, have a delayed response to allow temporary overcurrent conditions that might occur during normal operation without triggering the fuse.
