The Bussmann T-20 is a time-delay plug fuse designed for electrical circuits where motors frequently turn on and off. This 4-pack of 20-amp, 125-volt fuses provides reliable overload protection while accommodating the harmless inrush currents that occur during motor startup. Unlike standard fuses that may nuisance-trip on temporary surges, the T-20’s dual-element design distinguishes between brief motor starting currents and sustained dangerous overloads.
Whether you’re protecting equipment in industrial, commercial, or residential settings, the T-20 delivers dependable circuit protection. The four-piece pack ensures you have spares on hand for quick replacements, reducing downtime and maintenance costs.
Features and Benefits
- Time-delay (slow-blow) action: Distinguishes between harmless motor starting currents and dangerous sustained overloads, preventing nuisance trips.
- Dual-element design: A simple link element handles short circuits and dangerous overloads, while a series-connected element allows motor inrush currents to pass safely.
- T-plug construction: Fits standard fuse blocks for quick, tool-free replacement.
- Plastic body: Durable housing for reliable electrical protection.
- UL-approved protection: Delivers reliable 10 kA interrupt rating for 125-volt circuits.
- 4-pack quantity: Multiple fuses ensure you have spares on hand for immediate replacements.
