LPJ-8SP - 8 Amp Fuse

LPJ-8SP - 8 Amp Fuse

Choosing the right fuse takes more than matching the amp rating. The Eaton Bussmann series LPJ-8SP is an 8A Class J time-delay, current-limiting fuse rated for 600VAC and 300VDC. Eaton specifies interrupting ratings of 300 kAIC at 600VAC and 100 kAIC at 300VDC, along with a response time of 10 seconds at 500% of rated current. For electricians and maintenance teams, these clear specifications provide practical checkpoints for confirming the correct fuse before installation. When properly selected, installed by your qualified electrical personnel, and operated within its specified ratings, the LPJ-8SP is built to last as part of a properly designed and maintained electrical system.

Key Features and Benefits

• 8A Class J configuration: Provides clear amperage and fuse-class specifications to match the LPJ-8SP to compatible equipment.
• 600VAC / 300VDC voltage ratings: Supports applications requiring the manufacturer's specified AC or DC voltage rating.
• Time-delay operation: Eaton identifies the LPJ-8SP as a time-delay fuse, specifying a 10-second response time at 500% of rated current.
• Current-limiting fuse: Eaton classifies the LPJ-8SP as current-limiting, an important characteristic to confirm when selecting a fuse for the intended circuit.
• Dual-element construction: Uses two elements as specified by the manufacturer.
• High in-rush current motor protection: Eaton lists this characteristic as a special feature, making it relevant when evaluating the fuse for compatible motor applications.
• Ferrule-end connections: The ferrule-end × ferrule-end configuration provides another useful checkpoint for confirming physical compatibility.
• Non-indicating configuration: Eaton identifies the LPJ-8SP as non-indicating.

Where It Works Best

The Eaton Bussmann LPJ-8SP 8A Class J fuse is intended for compatible electrical equipment that requires its specific combination of time-delay operation, current-limiting characteristics, dual-element construction, and high in-rush current motor protection. It is especially relevant when maintaining compatible motor circuits or other equipment whose documentation calls for the LPJ-8SP or matching electrical and physical specifications.
