Bussmann LPJ-90SP 600V 90A Dual Element Time Delay Fuse Class J

The Bussmann LPJ-90SP is a Class J dual element time delay fuse designed for superior circuit protection in commercial and industrial electrical applications. This 600-volt, 90-amp fuse provides reliable overcurrent protection with time delay characteristics that allow temporary overloads while quickly clearing short circuits.

Key Features:

• Dual element time delay design prevents nuisance tripping during motor starting and other temporary overload conditions
• 600V AC rating with 90-amp capacity for demanding industrial circuits
• Class J current-limiting fuse reduces potential damage from short circuits by limiting peak let-through current
• UL Listed and meets dimensional requirements for Class J fuses per NEC specifications
• Rejection-style construction ensures only proper amperage replacements can be installed
• Bolt-on blade terminal design for secure mounting in disconnect switches and motor starters
• 200,000 AIC interrupting rating at 600V AC

The LPJ series is ideal for protecting motor circuits, transformers, and other inductive loads where time delay characteristics are essential. The current-limiting design helps protect downstream equipment and reduces arc flash hazards. This fuse is non-renewable and should be replaced when blown.
