Bussmann TCF90RN Time Delay Fuse

Bussmann TCF90RN Time Delay Fuse

Engineered for Enhanced Circuit Protection and Reliability

Overview

The Bussmann TCF90RN Time Delay Fuse delivers robust overcurrent protection for electrical systems requiring tolerance to temporary surge currents. Designed for resilience, this fuse prevents nuisance tripping during harmless inrush events while ensuring rapid response to sustained overloads or short circuits. Ideal for industrial, commercial, and residential applications, it safeguards sensitive equipment and wiring without compromising safety.

Key Features

• Time-Delay Design: Withstands initial current surges (e.g., motor startups or transformer energization) without blowing, minimizing operational disruptions.
• High Interrupt Rating: Reliably interrupts high-current faults, protecting circuits from damage due to short circuits or severe overloads.
• Durable Construction: Features a rugged ceramic body for thermal stability and arc suppression in demanding environments.
• Precision Performance: Consistent trip curve characteristics ensure predictable protection across temperature variations.
• Easy Identification: Clear “TCF90RN” labeling simplifies replacements and audits.

Typical Applications

• Motor control centers and HVAC systems
• Transformers, power supplies, and industrial machinery
• Branch circuit protection in electrical panels
• UPS systems and backup power units
