LPJ-50SP - 50 Amp Fuse

LPJ-50SP - 50 Amp Fuse

Getting the right fuse means checking more than the amp rating stamped on the label. The Eaton Bussmann series LPJ-50SP is a 50A, 600V Class J fuse with a manufacturer-specified 300 kAIC interrupting rating. It uses a ferrule-to-ferrule connection, and Eaton identifies it as non-indicating. Those specifications give electricians and maintenance professionals clear checkpoints for determining whether the LPJ-50SP meets the requirements of compatible electrical equipment. Physical fit matters as much: When correctly selected, professionally installed, and operated within its specified ratings, the LPJ-50SP is built to last as part of a properly designed and maintained electrical system.

Key Features and Benefits

• 50A Class J fuse: Rated at 50 amps and identified by Eaton as a Class J fuse for compatible electrical equipment.
• 600V rating: The manufacturer specifies a 600V voltage rating, providing an essential checkpoint when confirming electrical compatibility.
• Ferrule-end configuration: Uses a ferrule-end × ferrule-end connection for equipment designed around this connection style.
• Non-indicating specification: Eaton identifies the LPJ-50SP as a non-indicating fuse.
