The Bussmann RK1 Class fuses are designed to provide reliable protection against overcurrents in electrical circuits. These nonindicating, slow-blow fuses can withstand temporary inrush currents without blowing, preventing nuisance tripping during motor and equipment startups. They are time-delayed, allowing them to open and disconnect the circuit when subjected to sustained loads or short circuits. Their rejection feature ensures that they cannot be downgraded from a current-limiting system, providing an added layer of safety. The modified terminals ensure compatibility with Class R fuse holders and clips, preventing the installation of lower interrupting capacity fuses. These versatile fuses are ideal for use in newer equipment as well as upgrades in older installations from Class H or K fuses. With their current-limiting ability, they can protect electrical circuits from damage caused by overcurrent, making them a must-have for any electrical system.
Top product features:
- Time-delay provides extra time for circuits to react to overcurrents
- Nonindicating prevents users from manually determining if the fuse is blown
- Rejection feature ensures that lower interrupting capacity fuses cannot be installed
Top product applications:
- Protection against overcurrents in electrical circuits
- Suitable for newer equipment or upgrades from Class H or K fuses
- Use as a time-delay, nonindicating fuse in applications where nuisance tripping is common
