Bussmann LPJ-125SP 125 Amp 600V Class J Time-Delay Fuse

The Bussmann LPJ-125SP is a 125 amp, 600 volt AC Class J time-delay fuse designed for superior circuit protection in commercial and industrial electrical systems. This dual-element, current-limiting fuse provides excellent motor circuit protection and helps prevent nuisance tripping during harmless inrush currents while responding quickly to short circuits and overloads.

Key Features:

• 125 amp rating at 600 volts AC
• Class J current-limiting design with 200,000 AIC interrupting rating
• Time-delay dual-element construction for motor and general purpose applications
• Compact 1-5/8" x 6-1/4" cartridge dimensions fit standard Class J fuse blocks
• UL Listed and CSA certified for safety and reliability
• RoHS compliant and RMS rejection feature prevents replacement with non-current-limiting fuses

The LPJ-SP series fuses are ideal for protecting motor circuits, transformers, and other inductive loads where temporary overloads are normal during startup. The current-limiting design significantly reduces let-through energy, protecting downstream equipment and extending system life. Compatible with standard Class J fuse holders and designed to meet NEC requirements for motor branch circuit protection.
