LPN-RK-9SP - 9 Amp Fuse

LPN-RK-9SP - 9 Amp Fuse

When you're matching a replacement fuse, the 9A rating is only the first step in the specification check. The Eaton Bussmann series LPN-RK-9SP is a 9A Class RK1 time-delay, current-limiting fuse rated for 250VAC and 250VDC. Eaton specifies interrupting ratings of 300 kAIC at 250VAC and 100 kAIC at 250VDC, along with a dual-element design and a manufacturer-stated response time of 8 seconds at 500%. When correctly selected, installed by qualified electrical personnel, and operated within its specified ratings, this fuse is built to last as part of a properly designed and maintained electrical system.

Key Features and Benefits

• 9A Class RK1 configuration: Provides a clear starting point for matching the fuse to equipment requiring a 9-amp Class RK1 device.
• Time-delay operation: Eaton identifies the LPN-RK-9SP as a time-delay fuse, an important characteristic to verify when replacing an existing fuse.
• Current-limiting design: The manufacturer specifies current-limiting characteristics as part of this fuse's protection configuration.
• Dual-element construction: Another catalog-specific characteristic that helps distinguish the LPN-RK-9SP when checking compatibility.
• 250VAC and 250VDC ratings: Supports compatible AC or DC applications within the manufacturer's specified electrical ratings.
• Ferrule End × ferrule end connection: Helps with confirming the physical connection style required by the fuse holder and equipment.
• Non-indicating configuration: Eaton identifies this catalog number as non-indicating.

Material Compliance and Certifications

According to Eaton's supplied specifications, the LPN-RK-9SP is CE Marked. This manufacturer-stated compliance information can be useful when checking the fuse against applicable equipment, facility, project, or regulatory requirements. Do not assume additional certification or material-compliance designation without supporting manufacturer documentation.

Where It Works Best

The Eaton Bussmann LPN-RK-9SP 9A Class RK1 fuse is intended for compatible electrical equipment requiring its specific combination of a 9A amperage rating, 250VAC / 250VDC voltage ratings, Class RK1 configuration, time-delay operation, current-limiting characteristics, dual-element construction, and ferrule-end × ferrule-end connection. Its electrically isolated end cap is another catalog-specific detail worth checking when matching the required fuse configuration.
