LPN-RK-7SP - 7Amp Fuse Description
LPN-RK-7SP - 7Amp Fuse
When you're replacing a fuse, the amp rating is only one piece of the puzzle. Fuse class, voltage, interrupting rating, operating characteristics, and physical size must all match the application. The LPN-RK-7SP is a 7-amp Class R cartridge fuse with time-delay and current-limiting characteristics, rated for 250VAC with a specified 200 kA interrupting rating at 250VAC. When correctly selected, installed by qualified electrical personnel, and operated within its specified ratings, the LPN-RK-7SP is built to last as part of a properly designed and maintained electrical system.
Key Features and Benefits
- 7A Class R fuse: Provides the specified 7-amp rating in a Class R cartridge-style configuration.
- Time-delay operation: Intended for circuits specifically requiring time-delay fuse characteristics.
- Current-limiting design: Identified as a current-limiting fuse, an important characteristic when confirming compatibility with the protected circuit and equipment.
- Non-indicating configuration: The LPN-RK-7SP is identified as a non-indicating fuse.

Where It Works Best
The LPN-RK-7SP 7A fuse is intended for compatible electrical equipment that calls for a Class R, 7A, 250VAC cartridge fuse with time-delay and current-limiting characteristics and a 200 kA interrupting rating at 250VAC. Its clearly defined electrical ratings and compact dimensions also make it straightforward to evaluate for form, fit, and functional replacement applications where the existing equipment requires these same specifications.
