BUSSMANN LPJ-600SP Low Peak Fuse, 600 A, 600 V

Bussmann LPJ-600SP fuse is a Low-Peak fuse designed to blow quickly when an overcurrent occurs. This delay is intentional and ensures that momentary overcurrents that occur during normal operation, such as motor starting currents or short-duration power surges, do not cause the fuse to trip.

Working Mechanism:

• During regular operation, when the current flowing through the circuit is within the safe range, the fuse remains stable, and the circuit functions normally.
• When an overcurrent occurs, the delay mechanism begins to react, but it takes time to reach a critical point.
• Once the delay mechanism has absorbed enough heat or achieved a certain level of movement, it triggers the fuse's tripping mechanism.
• When the tripping mechanism activates, the fuse responds by breaking the circuit.
• This tripping prevents the excess current from causing damage.

Features:

• Bussmann LPJ-600SP Low-Peak fuse has a dual-element for time-delay and current-limiting functionalities.
• This fuse has an interrupt rating of 300kAIC at 600VAC to handle high-energy fault currents.
• It has a response time of 10 seconds at 500% of the rated current allowing for the safe start-up and operation of inrush-heavy equipment without the risk of unnecessary tripping.
• This Low-Peak fuse delivers consistent 2:1 ampacity ratios for seamless protection and minimised downtime.
• It has a melamine body to resist heat generated during resisting overcurrents.

Compatible Accessories:

• Bussmann BH-3144 Fuse Block: This fuse block eases the installation and can accommodate two fuses at once.

Frequently Asked Questions:

Q. How does a time-delay fuse differ from a standard fuse?

A. A standard fuse responds immediately to overcurrents and will blow if the current exceeds its rating. In contrast, a time-delay fuse intentionally introduces a delay in its response, allowing it to tolerate temporary overcurrents without tripping.

Q. Why are time-delay fuses important?

A. Time-delay fuses help prevent unnecessary disruptions caused by transient overcurrents during normal equipment operation. They strike a balance between protection and functionality, ensuring that essential equipment does not shut down due to harmless spikes in current.

Q. Can time-delay fuses offer the same level of protection as standard fuses?

A. Yes, time-delay fuses provide similar levels of protection against sustained overcurrents as standard fuses.

Q. Is this fuse indicating or non-indicating?

A. It is a non-indicating fuse. However, if you require an indicating fuse with a similar configuration, you can check out Bussmann LPJ-600SPI fuse that has easyID for convenient identification.
