Bussmann LPJ-12SP fuse offers protection against overcurrent conditions by interrupting the flow of electricity when current levels exceed safe limits. It is used in control panels, motor circuits and equipment requiring circuit protection.
Working Mechanism:
- Bussmann LPJ-12SP 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 sustained overcurrent conditions or short circuits, the current passing through the fuse becomes excessive. It has a dual element design.
- One element responds quickly to the high current, heating up and causing the fuse's element to melt or break. The second element of the fuse is designed with a time-delay characteristic. It's 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:
- Bussmann LPJ-12SP fuse has a melamine body for durability and resistance against heat & stains.
- It has an interrupt rating of 100kAIC at 300VDC and 300kAIC at 600VAC to promptly halt current flow under severe conditions.
- This Bussmann fuse has Class J configuration to prevent nuisance-blowing from motor and equipment startups.
- It has a current rating of 12A and voltage rating of 600VAC / 300VDC.
Frequently Asked Questions:
Q. How does the time-delay feature of Bussmann LPJ-12SP fuse work?
A. The time-delay feature allows the fuse to tolerate temporary overcurrent conditions, such as during motor startups, without immediately tripping. This prevents nuisance tripping and ensures 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.
