BUSSMANN LPJ-175SP Fuse 175a Class J Lpj 600vac/300vdc

Bussmann LPJ-175SP fuse is used in automotive, industrial, electronics and telecommunications applications for safeguarding electrical systems from overcurrent conditions.

Working Mechanism:

• When the electrical circuit experiences excess current beyond its rated capacity.
• The internal fuse element heats up due to the overcurrent.
• The fuse element melts at a predetermined temperature, breaking the electrical path.
• With the melted element, the circuit opens, preventing further current flow.
• This action protects the circuit and connected components from damage due to excessive current.

Features:

• This speed-time delay fuse has a nonrejection style, providing an interrupt rating of 100kA at 300VDC and 300kA at 600VAC.
• It features melamine construction for structural rigidity and a dual-element design with a 1-5/8 inch diameter for reduced nuisance tripping.
