BUSSMANN LPJ-30SP Low Peak Fuse, 30 A, 600 V

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.
