LPJ-70SP - 70 Amp Fuse

LPJ-70SP - 70 Amp Fuse

When you're matching a fuse to existing electrical equipment, 70 amps is only part of the story. Fuse class, voltage rating, interrupting capacity, connection style, dimensions, and certifications must all match the application. The Eaton Bussmann series LPJ-70SP is a 70A Class J fuse rated for 600V, with a manufacturer-specified 300 kAIC interrupting rating. When you correctly selected, installed by qualified electrical personnel, and operated within its specified ratings, the LPJ-70SP is built to last as part of a properly designed and maintained electrical system.

Key Features and Benefits

• 70A Class J fuse: Eaton specifies a 70-amp rating and Class J designation, two essential details to verify when matching a fuse to existing equipment.
• 600V rating: Rated for 600V, providing a clearly defined voltage specification for compatibility checks.
• Blade-end configuration: The blade-end × blade-end connection provides an important physical checkpoint when evaluating fit.
• Non-indicating fuse: Eaton identifies the LPJ-70SP as non-indicating.
