Overview
The Bussmann RES-10 is a Class H non-current-limiting renewable fuse designed for industrial power distribution systems. Rated at 10 amperes and 600 volts AC, this cartridge fuse features a time-delay (super-lag) characteristic that accommodates temporary inrush currents while protecting against sustained overloads. The renewable link design reduces operational costs by allowing the fuse element to be replaced without discarding the ferrule housing.
Key Features
- Class H cartridge fuse with 10 kA symmetrical interrupting capacity
- Super-lag (time-delay) characteristic for motor and transformer circuits
- Renewable fuse element—cost-effective alternative to single-use fuses
- Ferrule terminals (0.81″ diameter, 5″ length) for standard cartridge holders
- UL listed per UL 248-14 standard
- Suitable for circuits with available fault current less than 10,000 amperes
