Bussmann TCF50RN Time Delay Fuse – 50 Amp, 250V AC

Reliable Circuit Protection for Demanding Applications

The Bussmann TCF50RN is a premium time-delay (slow-blow) fuse designed to safeguard electrical circuits from overloads and short circuits while accommodating temporary inrush currents. Part of Eaton’s trusted Bussmann series, this 50-amp fuse combines robust protection with exceptional durability for industrial, commercial, and residential systems.

Key Features

• Time-Delay Design: Withstands initial surge currents (e.g., motor startups, transformer energization) without nuisance tripping, while responding decisively to sustained overloads.
• High Interrupting Rating: 200,000 AIC (Ampere Interrupting Capacity) ensures reliable protection against high-fault currents.
• Voltage Rating: 250V AC for versatile use in low-voltage AC circuits.
• Rejection Base (Type T): Prevents accidental installation of incorrect fuse types, enhancing safety compliance.
• Dual-Element Construction: Provides precise overload protection (thermal response) and rapid short-circuit interruption (link element).
• Compact Size: Industry-standard 30mm (1-1/4″) length fits common fuse holders and panels.

Ideal Applications

• HVAC systems (compressors, blower motors)
• Industrial control panels and transformers
• Power supplies, UPS units, and distribution boards
• Machinery with inductive loads requiring inrush tolerance
