LPJ-7SP - 7 Amp Fuse

LPJ-7SP - 7 Amp Fuse

Getting the right fuse means checking more than the amp rating on the label. The Eaton Bussmann series LPJ-7SP is a 7A 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 dual-element construction and a ferrule-end-to-ferrule connection. Eaton also lists high in-rush current motor protection, a key specification to consider when evaluating this fuse for compatible motor applications. When properly selected, installed by your qualified electrical personnel, and operated within its specified ratings, the LPJ-7SP is built to last as part of a correctly designed and maintained electrical system.

Key Features and Benefits

• 7A Class J configuration: The 7-amp rating and Class J designation provide two important identification points when checking the LPJ-7SP against equipment requirements.
• 600VAC / 300VDC voltage ratings: Eaton specifies this fuse for 600VAC and 300VDC, making voltage compatibility straightforward to verify.
• Time-delay characteristics: The LPJ-7SP is a time-delay fuse, an important characteristic when matching a fuse to the circuit's protection requirements.
• Current-limiting fuse: Eaton classifies the LPJ-7SP as current-limiting, providing another key specification for proper fuse selection.
• Dual-element construction: Eaton specifies a dual-element design for this model.
• Manufacturer-stated response time: Eaton specifies a 10-second response time at 500%. Consider this figure under the manufacturer's stated conditions rather than as a universal clearing time.
• Ferrule-end connection: The ferrule-end × ferrule-end configuration provides a clear physical detail to verify when matching the fuse to existing equipment.
• Non-indicating: Eaton identifies the LPJ-7SP as a non-indicating fuse.

Where It Works Best

The Eaton Bussmann LPJ-7SP 7A Class J fuse is intended for compatible electrical equipment requiring its specific combination of 7A capacity, 600VAC / 300VDC ratings, time-delay operation, current-limiting characteristics, dual-element construction, and ferrule-end connections. Eaton's stated high in-rush current motor protection is also relevant when considering this fuse for compatible motor applications.
