Fuse Class RK1 200A LPN-RK-SP Series
The Fuse Class RK1 200A LPN-RK-SP Series from Bussmann is a time-delay, nonindicating UL Class RK1 fuse that provides reliable overcurrent protection for electrical circuits. Tolerant of temporary inrush currents, it prevents nuisance blowing from motor and equipment startups while also opening to disconnect the circuit when exposed to sustained loads and short circuits. Its rejection feature ensures proper installation with current-limiting capacity, making it ideal for upgrading older installations or newer equipment. With a capacity of 200 Amps, this fuse is suitable for a variety of applications in industrial, commercial, and residential settings.
Top product features:
- Time-delay protection against nuisance blowing from motor and equipment startups
- Current-limiting capacity for improved overcurrent protection
- Modified terminals to prevent accidental downgrade from a current-limiting system
Top product applications:
- Home appliances: Used in circuits that have heavy start-up currents like refrigerators or air conditioners to prevent damage and prolong their lifespan
- Lighting systems: Installed as part of a branch circuit in buildings or industrial facilities where there is a high risk of overcurrent, such as offices, schools or hospitals
- Outdoor use: Ideal for protecting outdoor equipment like pumps or irrigation systems from overloading or short circuits during startup, helping to maintain their functionality and safety
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.
