Bussman LPJ-15SP fuse is used in electrical systems to protect against overcurrent situations. It is suitable for commercial and industrial settings and is ideal to prevent excessive currents. This preventive measure avoids equipment damage and reduces the risk of fire hazards.
Working Mechanism:
- Bussmann LPJ-15SP fuse operates on its time-delay and current interruption characteristics. When normal current flows through the fuse, it remains intact due to the metal conductor within it.
- If there's a sudden surge in current, while motor startups, it allows temporary inrush without immediately tripping.
- In the case of overcurrent conditions or short circuits, the current passing through the fuse becomes excessive.
- It has a dual element design with one element responding quickly to the high current, heating up and causing the fuse's element to melt or break.
- The second element of the fuse offers a time-delay characteristic and is a bit slower to respond to overcurrent conditions. This element allows the fuse to tolerate temporary surges without tripping, which is particularly useful in situations where devices like motors can cause momentary spikes in current during their startup phase.
Features:
- Bussman LPJ-15SP fuse has a response time of 10 seconds at 500% overload.
- This Class J style fuse prevents nuisance-blowing from motor and equipment startups.
- This fuse has a cylindrical body design for a secure fit and minimising the risk of loose connections.
- It comes with a dual element having melamine body material to enhance reliability and resilience.
Frequently Asked Questions:
Q. How does the time-delay feature of this Bussmann LPJ-15SP fuse work?
A. The time-delay feature allows the fuse to tolerate temporary overcurrent conditions without immediately tripping, ensuring stability during transient events.
Q. What is the significance of the lack of visual indication on this fuse?
A. The lack of visual indication means that the fuse itself doesn't show if it's blown. It may require an indicating fuse block or cover for blown fuse identification.
