Fuse Class RK5 500A FRS-R Series
The Bussmann Fuse Class RK5 500A FRS-R Series offers unmatched protection for electrical circuits against overcurrent hazards in a wide range of industrial and commercial applications. Its time delay feature ensures that it doesn't nuisance-blow during startups, while its moderate current-limiting capabilities provide excellent circuit protection against short circuits and sustained loads. The nonindicating fuse design is perfect for preventing false indications and eliminating the need for regular checking, enhancing system reliability and uptime. With its rejection feature that prevents accidental downgrade and compatible size with Class H and K fuses, this RK5 series ensures secure installation in any Class R fuse holder for optimum overcurrent protection.
Top product features:
- Modified terminals ensure compatibility with Class R fuse holders for secure installation.
- Time delay and non-indicating design prevent false indications and nuisance-blowing during startup.
- Slow-blow, moderate current limiting offers excellent overcurrent protection against short circuits and sustained loads.
Top product applications:
- Use in general purpose applications where current-limiting RK1 fuses are not necessary.
- Upgrading older installations from Class H or K fuses for improved overcurrent protection.
- Protection against short circuits and sustained loads in newer equipment.
These 600VAC UL Class RK5 fuses are time delay and nonindicating. They tolerate temporary inrush currents without opening, which prevents nuisance-blowing from motor and equipment startups. Also called slow-blow Class RK5 fuses, these 200kA IR fuses 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 RK5 fuses provide moderate current limitation for general use applications where more current-limiting RK1 fuses aren't needed. These fuses have an interrupting rating (IR) of 200kA and 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. They are current-limiting to prevent electrical damage by disconnecting circuits before they're exposed to the full magnitude and duration of an overcurrent.
