Bussmann LPJ-30SP Low-Peak fuse is a time delay fuse that uses long time-delay to minimise needless fuse openings due to temporary overloads and transient surges. It is used to control the timing of switching operations in a motor startup.
Working Mechanism:
- Bussmann fuse works by melting when the current passing through it exceeds its rated value.
- This melting of the fuse element breaks the circuit, stopping the current flow.
- This action protects the circuit from damage due to excessive current.
Features:
- Bussmann LPJ-30SP Low-Peak fuse has two elements for both time-delay and current-limiting functions.
- Its long time delay minimises unnecessary fuse openings due to temporary overloads andtransient surges.
- The current limiting capability of this fuse protects downstream components from harmful thermal and magnetic effects of short-circuit currents.
- This fuse has a melamine body to resist heat generated during resisting overcurrents.
Frequently Asked Questions:
Q. What is the interrupt rating of this Bussmann fuse?
A. It has an interrupt rating of 100kA at 300VDC and 300kA at 600VAC.
Q. How do I test a fuse to see if it's blown?
A. You can use analogue multimeters or digital multimeters to test whether the fuse has blown or not.
Q. What precautions should I take when replacing a blown fuse?
A. When replacing a blown fuse, ensure that the circuit is de-energised to prevent electric shock.
