Bussmann 600V Class J Time-Delay Fuse

The Bussmann 600V Class J time-delay fuse line (Low-Peak series) provides dependable overcurrent protection for motors, transformers, and other electrical equipment in industrial and commercial power systems. These current-limiting fuses are also known as Class J dual-element or time-delay cartridge fuses.

Key Features:

• 600V AC voltage rating for use in a wide range of power distribution circuits
• Class J design with a time-delay characteristic that tolerates temporary motor starting and inrush currents without nuisance opening
• Current-limiting performance helps reduce let-through energy during short-circuit faults and protects downstream components
• High interrupting rating for use on circuits with high available fault current
• Compact Class J dimensions allow space-saving installation in fuse blocks, holders, and disconnect switches
• Built by Bussmann, a long-established name in circuit protection

These fuses suit motor branch circuits, feeder protection, and control panel applications where reliable, selective protection is needed. Select the amperage rating that matches your circuit requirements.
