LPJ-5SP - 5 Amp Fuse

LPJ-5SP - 5 Amp Fuse

Choosing the right fuse is about more than finding 5A printed on the label. Voltage, fuse class, interrupting rating, time-delay characteristics, connection style, and physical dimensions all matter when you're checking compatibility. The Eaton Bussmann series LPJ-5SP is a 5A Class J time-delay, current-limiting fuse rated for 600VAC and 300VDC. For maintenance teams and electricians, those details make it easier to determine whether this exact fuse matches an existing application rather than relying on appearance or amperage alone. When you correctly select, install by qualified electrical personnel, and operate within its specified ratings, the LPJ-5SP is built to last as part of a properly designed and maintained electrical system.

Key Features and Benefits

• 5A Class J fuse: Eaton specifies a 5-amp rating and Class J designation, giving technicians two essential identification points when checking compatibility.
• 600VAC / 300VDC rating: Designed for applications requiring its manufacturer-specified 600VAC or 300VDC voltage rating.
• Time-delay operation: The LPJ-5SP is a time-delay fuse, an important characteristic to verify when matching the equipment's protection requirements.
• Current-limiting design: Eaton classifies this model as current-limiting, providing another key specification for circuit-protection selection.
• Dual-element construction: Eaton specifies a dual-element design.
• High in-rush current motor protection: Eaton specifically lists high in-rush current motor protection as one of the LPJ-5SP's features.
• Ferrule-end connection: The ferrule-end × ferrule-end configuration provides an important physical checkpoint when comparing the fuse with existing equipment.
• Non-indicating: Eaton identifies the LPJ-5SP as a non-indicating fuse.

Where It Works Best

The Eaton Bussmann LPJ-5SP 5A Class J fuse is intended for compatible electrical equipment that requires its combination of 5A current rating, 600VAC / 300VDC voltage ratings, time-delay operation, current-limiting characteristics, and dual-element construction. Eaton's stated high in-rush current motor protection is another important consideration when evaluating the LPJ-5SP for compatible motor-protection applications.
