Bussmann LPJ Series Class J Time-Delay Fuse, 600V

Bussmann LPJ Series Class J Time-Delay Fuse, 600V

The Bussmann LPJ Series (LPJ-SP, cross-referenced as BUSS LPJ-SP) is a family of Class J time-delay fuses rated for 600V, engineered to deliver dependable overcurrent protection in demanding electrical systems. This product page covers the LPJ Series across its available Ampere Ratings of 2.25 A, 3 A, and 5.6 A, letting electrical contractors and maintenance teams select the exact fuse value required for a given circuit while standardizing on one recognized Class J platform. As part of Bussmann's Class J fuse lineup, every LPJ Series fuse combines a time-delay (TD) response characteristic with the shared 600V voltage rating to help safeguard circuits, equipment, and conductors from damaging fault and overload conditions. Whether specifying the 2.25 A, 3 A, or 5.6 A option, buyers get the same Class J form factor, time-delay performance, and Bussmann manufacturing quality, making it easy to cross-reference and replace fuses consistently across a facility's electrical distribution system.

Key Features

• Ampere Rating Range: Available in 2.25 A, 3 A, and 5.6 A ratings, allowing precise matching to the connected load and conductor ampacity.
