Fuse Class RK5 250A FRS-R Series
The Bussmann Fuse Class RK5 250A FRS-R Series provides enhanced protection for electrical circuits with moderate current limitations in general use applications. These slow-blow fuses are time-delayed and non-indicating, ensuring that they won't blow during startups or when exposed to temporary surges. They have a high interrupting rating of 200kA and an upgraded rejection feature that prevents accidental downgrades from current-limiting systems. They're suitable for use with Class H fuse holders to improve overcurrent protection in older installations or with newer equipment designed for Class RK5 fuses. With a high resistance to nuisance-blowing, these fuses provide stable and reliable circuit protection for a wide range of applications.
Top product features:
- Time-delayed and non-indicating
- Tolerate temporary inrush currents
- High interrupting rating of 200kA
Top product applications:
- Home appliances and electronics
- Lighting systems
- 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.
