Bussmann DFJ-90 – Drive Fuse

Part Number: 051712653404

Overview

The Bussmann DFJ-90 is a high-performance fuse engineered for robust protection of variable frequency drives (VFDs) and adjustable speed drives (ASDs). Ideal for industrial automation, HVAC systems, and motor control applications, this fuse safeguards sensitive drive components from damaging overloads and short circuits. Its precision design ensures reliability in demanding environments, minimizing downtime and maintenance costs.

Key Features

• Specialized Drive Protection: Optimized to handle the unique electrical stresses of VFDs/ASDs, including inrush currents and harmonic distortions.
• Time-Delay Characteristic: Allows temporary overloads (e.g., motor startups) without nuisance tripping while responding rapidly to fault conditions.
• High Interrupt Capacity: Rated for 200 kA at 700V AC, providing superior short-circuit protection.
• Compact & Efficient: Space-saving design simplifies installation in control panels and enclosures.
• Durable Construction: Precision-engineered elements resist thermal cycling and mechanical stress for long service life.
• Compliance: Meets global safety standards (UL/CSA certified).
