Bussmann TCF70RN Low Peak Fuse

Bussmann TCF70RN Low Peak Fuse

Engineered for Precision Protection in Demanding Electrical Systems

Overview

The Bussmann TCF70RN Low Peak Fuse delivers exceptional overcurrent protection for industrial and commercial applications. Designed with Eaton’s renowned engineering expertise, this time-delay (dual-element) fuse minimizes peak let-through current during short circuits while handling temporary overloads without nuisance tripping. Ideal for safeguarding transformers, motors, and capacitors, it ensures reliable operation in critical circuits.

Key Features

• Low Peak Design: Drastically reduces destructive let-through energy during high-level faults, enhancing downstream equipment protection.
• Time-Delay Performance: Withstands inrush currents up to 10x the rated current for 10 seconds, preventing false trips during motor startups.
• High Interrupting Rating: 300kA at 600V AC (UL/CSA certified), ensuring safety in high-fault environments.
• Compact & Efficient: Space-saving form factor (70A rating) optimizes panel layout without compromising performance.
• Durable Construction: Sand-filled ceramic body resists thermal stress and arc flash, extending service life.
• Easy Compliance: Meets UL 248-14/CSA C22.2 standards for branch circuit protection.

Applications

• Motor control centers (MCCs)
• Power distribution panels
• Transformers and capacitor banks
• HVAC systems and industrial machinery
