Bussmann TCF45RN Time-Delay Fuse

Overview

The Bussmann TCF45RN is a high-performance time-delay (slow-blow) fuse designed for reliable circuit protection in demanding applications. Engineered to handle temporary current surges without nuisance tripping, this fuse safeguards motors, transformers, and inductive loads while providing robust defense against sustained overloads and short circuits.

Key Features

• Time-Delay Design: Tolerates initial inrush currents (e.g., motor startups) without blowing, while interrupting prolonged overloads.
• 45 Amp Rating: Optimized for circuits requiring precise 45-ampere protection.
• 250V AC Voltage Rating: Suitable for standard industrial and commercial voltage systems.
• Rejection Base (Type “R”): Prevents accidental installation in incompatible fuseholders, enhancing safety and compliance.
• High Interrupting Capacity: 200,000 AIC (Amperes Interrupting Capacity) ensures reliable protection under extreme fault conditions.
• Dual-Element Construction: Separately manages overloads (delayed response) and short circuits (instant response) for optimal performance.
• UL Listed & CSA Certified: Meets rigorous North American safety standards.

Applications

• Motor control circuits (HVAC, pumps, compressors)
• Transformers and power supplies
• Industrial machinery with inductive loads
• Conveyor systems and manufacturing equipment
• Commercial lighting panels
