LPJ-2SP - 2 Amp Fuse

LPJ-2SP - 2 Amp Fuse

When you're matching a replacement fuse, the small details matter just as much as the amp rating. The Eaton Bussmann series LPJ-2SP is a 2A 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. When correctly selected, installed by qualified personnel, and operated within its specified ratings, the LPJ-2SP is built to last as part of a properly designed and maintained electrical system.

Key Features and Benefits

• 2A Class J fuse: Rated at 2 amps and designed in the Class J configuration for compatible electrical equipment.
• AC and DC voltage ratings: Eaton specifies the LPJ-2SP for 600VAC and 300VDC, making voltage an important checkpoint when confirming the application.
• Time-delay design: Eaton identifies this model as a time-delay fuse and specifies a response time of 10 seconds at 500% of rated current.
• Current-limiting fuse: The LPJ-2SP is manufacturer-specified as a current-limiting fuse.
• Dual-element construction: Uses a dual-element configuration together with its specified time-delay characteristics.
• High in-rush current motor protection: Eaton lists high in-rush current motor protection among the LPJ-2SP's special features.
• Ferrule-end configuration: Uses ferrule-end × ferrule-end connections, an important physical detail to confirm when matching a fuse to existing equipment.

Where It Works Best

The Eaton Bussmann LPJ-2SP 2A Class J fuse is intended for compatible electrical equipment that requires its combination of 2A amperage, 600VAC/300VDC ratings, time-delay operation, current-limiting characteristics, and ferrule-style connections. Eaton also identifies high in-rush current motor protection as a special feature, making the fuse relevant to compatible motor applications where the equipment specifications call for these characteristics.
