LPN-RK-100SP - 100 Amp Fuse

LPN-RK-100SP - 100 Amp Fuse

A fuse must match the application in more than amperage alone, and the Eaton Bussmann series LPN-RK-100SP gives you several specific ratings to check before installation. This 100A Class RK1 time-delay, current-limiting fuse is rated for 250VAC and 250VDC, with Eaton specifying interrupting ratings of 300 kAIC at 250VAC and 100 kAIC at 250VDC. When correctly selected, installed by your qualified electrical personnel, and operated within its specified ratings, the LPN-RK-100SP is built to last as part of a properly designed and maintained electrical system.

Key Features and Benefits

• 100A Class RK1 configuration: Provides the specific amperage and fuse-class combination needed when matching equipment designed for a 100A Class RK1 fuse.
• Time-delay operation: Eaton identifies the LPN-RK-100SP as a time-delay fuse, an important operating characteristic to confirm when selecting a replacement.
• Current-limiting characteristics: Eaton specifies the fuse as current-limiting, giving maintenance personnel another key protection characteristic to verify against equipment requirements.
• Dual-element construction: Uses a dual-element design as specified by the manufacturer.
• 250VAC / 250VDC ratings: Rated for compatible AC and DC applications within the manufacturer's stated limits.
• Blade end × blade end connection: Provides an important physical checkpoint when confirming fit with compatible fuse holders and equipment.
• Non-indicating configuration: Eaton identifies the LPN-RK-100SP as non-indicating.

Material Compliance and Certifications

According to Eaton's supplied specifications, the LPN-RK-100SP is RoHS Compliant and CE Marked. These manufacturer-stated designations provide useful reference points when evaluating the fuse against applicable equipment, project, facility, or regulatory requirements. Do not assume any additional certification or compliance designation without supporting manufacturer documentation.

Where It Works Best

The Eaton Bussmann LPN-RK-100SP 100A Class RK1 fuse is intended for compatible electrical equipment requiring a 100A rating, 250VAC / 250VDC voltage ratings, Class RK1 configuration, time-delay operation, current-limiting characteristics, dual-element construction, and a blade-end × blade-end connection. Eaton also lists high in-rush current motor protection as a special feature, making that manufacturer-stated characteristic relevant when evaluating the fuse for compatible motor protection applications.
