Fuse Class RK5 225A FRS-R Series
Introducing the Bussmann Fuse Class RK5 225A FRS-R Series, a versatile fuse designed to provide optimal protection for your electronic devices and appliances. These fuses offer enhanced current-limiting capabilities for moderate load applications, preventing electrical damage caused by overcurrent events such as short circuits and sustained loads. The time delay and nonindicating nature of these fuses ensures that they do not blow in response to transient currents, minimizing the risk of false tripping and improving overall reliability. Perfect for use in new or upgraded installations, Bussmann's Class RK5 fuses feature modified terminals compatible with standard Class R fuse holders, ensuring a secure fit and reliable performance. Trust Bussmann to deliver quality products that safeguard your equipment from electrical hazards!
Top product features:
- Time delay and nonindicating prevents nuisance-blowing from motor and equipment startups
- Modified terminals ensures a secure fit and reliable performance
- Interrupting rating of 200kA provides moderate current limitation for general use applications
Top product applications:
- Protecting electronic devices and appliances from short circuits and overcurrent events in general-use applications
- Upgrading older installations from Class H or K fuses for improved overcurrent protection
- Preventing nuisance tripping due to temporary inrush currents during motor and equipment startups
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.
