Bussmann DFJ-200 High Speed Fuse 200A 600 Vac or Less 450 Vdc or Less Class J Melamine Tube

Description

Features

• Featuring standard Class J cartridge dimensions (1.63 in times 5.75 in) and durable blade-end terminations, the DFJ-200 integrates seamlessly into readily available industrial hardware. This eliminating the need to source specialized or proprietary high-speed fuse holders, allowing maintenance electricians to drop specialized drive protection directly into existing panel configurations and drastically lower retrofitting overhead.
• Boasting a massive 200 kAIC clearing capacity at 600V AC (and 100 kAIC at 450V DC), this current-limiting fuse safely manages immense electrical faults without exploding or damaging surrounding control gear. This exceptionally high interrupting capacity ensures full compliance with rigid NEC® branch circuit protection laws, making it an excellent choice for major industrial mains, manufacturing sub-panels, and high-capacity electrical distribution centers.
• Constructed with a premium, heavy-walled melamine housing, the fuse body resists physical fracturing, intense arc tracking, and severe dimensional shifting under fluctuating load cycles. This industrial-grade material ensures optimal heat dissipation and arc-quenching safety during continuous-duty cycling, preserving electrical system integrity within hot and punishing manufacturing control cabinets.
• Explicitly rated for up to 600V AC and 450V DC systems, this versatile 200-amp cartridge streamlines safety layouts across mixed power applications. It functions flawlessly whether deployed on primary AC input lines or embedded into heavy-duty DC traction systems, power converters, and centralized inverters, simplifying warehouse inventory management for large-scale industrial operations.
