BUSSMANN LPJ-400SP Low Peak Fuse, 400 A, 600 V

Bussmann LPJ-400SP low peak fuse is used in various industrial machinery, power distribution and electrical panels. It protects electrical circuits by safely interrupting current flow in case of overloads or faults.

Working Mechanism:

• The fuse allows normal electrical current to flow through it.
• When an overload or fault occurs, the fuse senses excessive current.
• The fuse features time delay characteristics, allowing it to withstand temporary surges without blowing.
• If the fault persists beyond the delay, the fuse interrupts the circuit, preventing damage or hazards.

Features:

• This LPJ-400SP fuse has melamine construction for durability and increased electrical insulation.
• It has an AC voltage rating of 600VAC and DC voltage rating of 300VDC.
• This fuse measures 7-1/8 inches in length and has a diameter of 2-1/8 inches.
• It features a non-indicating blade-style body for increased performance.
• This low peak fuse comes in a dual-element design to prevent electrical hazards.
• It offers an interrupt rating of 100kA at 300VDC and 300kA at 600VAC.
