Fuse Class RK1 70A LPS-RK-SPI Series

Upgrade your electrical protection with the time-delay Class RK1 70A fuse from Bussmann. These slow-blow fuses are designed for motor starts, and can handle temporary inrush currents without blowing prematurely. The visual indicator makes it easy to identify when a fuse has blown, ensuring quick replacement. This fuse also includes rejection clips that prevent installation into lower-capacity fuse holders, offering superior overcurrent protection for newer equipment and an upgrade from older installations using Class H or K fuses. With their current-limiting design, the RK1 fuses protect your electrical circuits from damage and disconnect them quickly when exposed to sustained loads or short circuits. These versatile fuses fit in the same size holder as Class H and K fuses, making them an easy upgrade for added peace of mind and safety in a variety of applications.

Top product features:

  • Time-delay, indicating feature for easy identification of blown fuses.
  • Current-limiting capability for enhanced overcurrent protection.
  • Fits in the same size holder as Class H and K fuses for a simple upgrade.

Top product applications:

  • Protect electrical circuits in new equipment from temporary inrush currents.
  • Upgrade older installations with improved overcurrent protection for motor starts.
  • Prevent nuisance-blowing during motor and equipment startups while providing current-limiting capabilities.
Time-delay, indicating 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 a visual indicator to make it easier to identify blown fuses for replacement.

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.
