Bussmann LPJ-80SP Dual-Element Time-Delay Fuse 80A 600V Class J

The Bussmann LPJ-80SP is a Class J dual-element time-delay fuse designed to provide superior overcurrent protection for motor circuits, transformers, and other electrical equipment with high inrush currents. This 80-amp, 600-volt fuse combines time-delay characteristics with exceptional current-limiting performance to protect against both overloads and short circuits.

Key Features:

• Dual-element design provides time-delay on overloads and fast-acting protection on short circuits
• Class J current-limiting fuse with 200kA interrupting rating at 600VAC
• 80-amp rating suitable for medium-duty motor and circuit protection
• Compact dimensions: 19.05mm x 117.60mm (3/4" x 4-5/8")
• 600-volt maximum operating voltage for commercial and industrial applications
• UL Listed and CSA certified for safety and reliability
• Rejection-style design prevents replacement with non-current-limiting fuses
• Low peak let-through current minimizes damage to downstream components

The LPJ series fuses are ideal for protecting motor control centers, combination starters, and branch circuits where both overload tolerance and short-circuit protection are critical. The time-delay feature allows temporary harmless overloads and motor starting currents while providing fast interruption of damaging short circuits.
