The Fuse Class RK5 300A FRN-R Series from Bussmann is a perfect solution for providing reliable overcurrent protection in general use applications. These fuses are designed to limit moderate currents and disconnect circuits when exposed to sustained loads and short circuits, preventing electrical damage. The rejection feature ensures that only the correct rating of fuse can be used, enhancing safety. These fuses are UL-listed and have a 200kA interrupting rating, making them ideal for applications where a higher level of overcurrent protection is required. They have a compact size and modified terminals, allowing them to fit into various types of fuse holders, including newer equipment. The Class RK5 fuses are non-indicating, so they don't require periodic replacement like other fuses. Their ability to tolerate temporary inrush currents without opening makes them suitable for use with motors and equipment startups. Overall, these fuses provide an effective and reliable solution for improving overcurrent protection and safety in various applications.
Top product features:
- Time delay and nonindicating Prevents nuisance-blowing from motor and equipment startups.
- Modified terminals Ensures a match with the rejection clips in Class R fuse holders for improved safety.
- 200kA interrupting rating Provides higher level of overcurrent protection for general use applications.
Top product applications:
- General use applications Moderate current limitation for various electrical circuits and devices that require overcurrent protection.
- Newer equipment installations Compatible with newer fuse holders and newer electrical systems to provide safe and reliable overcurrent protection.
- Upgrading older installations Used in conjunction with Class H fuse holders to enhance the level of overcurrent protection for older electrical systems without changing the size or structure of existing fuse holders.
