Overview
The Bussmann Type T Fusetron time-delay plug fuse box contains 23 fuses designed for reliable overcurrent protection in industrial and commercial electrical systems. Type T fuses feature dual-element, time-delay construction that tolerates temporary motor inrush currents without opening, making them ideal for circuits where motors start frequently. With Edison base threads and a 125V AC rating, these plug fuses thread directly into standard fuse receptacles in panel boxes and fuse holders.
Key Features
- Dual-Element Time-Delay Design: Heavy-duty fuses featuring dual-element construction with spring-loaded design for superior short-circuit and overload protection
- Motor Circuit Rated: Will not open under repeated motor startups while maintaining full overload protection
- Edison Base (Brass Threads): Edison Base with brass threads for compatibility with standard non-rejection fuse receptacles
- Industrial Strength: Industrial strength product providing superior protection
- Clear Window Design: Extra large clear window makes it easy to see if fuse is blown
- UL Listed: UL (Underwriter’s Laboratories) listed for safety compliance
