LPJ-1SP - 1 Amp Fuse

LPJ-1SP - 1 Amp Fuse

When your application calls for a 1-amp Class J fuse, matching the complete specification matters—not just the amperage printed on the fuse. The Eaton Bussmann series LPJ-1SP is a 1A time-delay, current-limiting fuse rated for 600VAC and 300VDC. For electricians and maintenance teams, those details provide clear reference points when checking an existing fuse or equipment requirements. The LPJ-1SP is also CE-marked and RoHS-compliant. Correctly selected, installed, and operated within its specified ratings, it's built to last as part of a properly designed and maintained electrical system.

Key Features and Benefits

• 1A Class J configuration: Designed for compatible equipment requiring a 1-amp Class J fuse with the LPJ-1SP's specified electrical characteristics.
• Time-delay operation: Allows for temporary inrush conditions associated with normal equipment startup when properly applied.
• High-inrush-current motor protection: Eaton identifies the LPJ-1SP as having characteristics for applications involving high motor inrush current.
• Current-limiting design: Provides the specified current-limiting characteristics for circuits designed around this type of fuse protection.
• Dual-element construction: Uses two elements in its time-delay fuse design.
• 600VAC and 300VDC ratings: Defined AC and DC ratings provide important reference points when checking compatibility with the intended circuit.
• Manufacturer-specified response: Eaton lists a response time of 10 seconds at 500% of rated current.
• Ferrule-style connections: The ferrule-end × ferrule-end configuration provides a defined physical connection for compatible fuse holders and equipment.
