Bussmann TCF50 Low Peak Time-Delay Fuse

Overview

The Bussmann TCF50 Low Peak Fuse by Eaton delivers reliable, high-performance circuit protection for demanding electrical systems. Engineered with low peak current-limiting technology, this fuse minimizes energy let-through during fault conditions to safeguard sensitive equipment against damaging short-circuit currents. The time-delay design provides excellent inrush tolerance while maintaining precise overload protection.

Key Features

• Low Peak Technology: Significantly reduces peak fault currents (up to 50% lower than standard fuses) to protect downstream components.
• Time-Delay Characteristic: Withstands temporary inrush currents (motors, transformers, solenoids) without nuisance tripping.
• High Interrupting Rating: 200kA at 125V AC/DC for robust protection in critical applications.
• Compact Size: Space-efficient 1″ x 0.25″ (13.3mm x 6.3mm) cylindrical design.
• Durable Construction: Sand-filled ceramic body with tin-plated brass end caps for corrosion resistance.
• Compliance: Meets UL/CSA 248-14 standards for fuses.
