Fuse Class RK1 150A LPS-RK-SP Series

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
Time-delay, nonindicating UL Class RK1 fuses tolerate temporary inrush currents without opening, which prevents nuisance-blowing from motor and equipment startups. Also called slow-blow Class RK1 fuses, they open to disconnect an electrical circuit when exposed to sustained loads and short circuits. They have no indicator for identifying a blown fuse, so they're sometimes used with an indicating fuse block or cover.

UL Class RK1 fuses are more current-limiting than RK5 fuses to react more quickly to overcurrent. These fuses are the same size as Class H and K fuses, but have a rejection feature that prevents an accidental downgrade from a current-limiting system. Their modified terminals ensure a match with the rejection clips in Class R fuse holders that prevent the installation of fuses with a lower interrupting capacity. They're typically used in newer equipment, but can also be used with a Class H fuse holder to upgrade older installations from Class H or K fuses for improved overcurrent protection. These fuses are current-limiting to prevent electrical damage by disconnecting circuits before they're exposed to the full magnitude and duration of an overcurrent.
