Fuse Class RK1 70A LPS-RK-SP Series

The Class RK1 70A LPS-RK-SP Series fuse from Bussmann is an excellent solution for upgrading your electrical installations. These current-limiting fuses are designed with time-delay and non-indicating features that make them ideal for use in motor and equipment startups, where nuisance-blowing can be a common issue. With their capacity to handle sustained loads and short circuits, these fuses provide exceptional protection against overcurrent scenarios. The rejection feature ensures compatibility with Class R fuse holders, preventing accidental downgrades from current-limiting systems. Their small size makes them easy to install, while the modified terminals make it simple to match the fuse with compatible equipment. Upgrade your electrical systems today with these high-quality Bussmann fuses and experience the benefits of enhanced safety, reliability, and performance!

Top product features:

  • Time-delay protection against nuisance-blowing
  • Current-limiting capability for enhanced overcurrent protection
  • Compatibility with Class R fuse holders for added safety and reliability

Top product applications:

  • Protecting electrical circuits in equipment and machinery that experiences sudden surges of current during startup
  • Guarding against overloads in lighting fixtures or outlets to prevent damage from prolonged use
  • Safeguarding electronic devices from power fluctuations and short circuits for optimal performance and reliability
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.
