LPJ-90SP - 90 Amp Fuse

LPJ-90SP - 90 Amp Fuse

Choosing the right fuse means checking more than the amperage printed on the label. The Eaton Bussmann series LPJ-90SP is a 90A Class J time-delay, current-limiting fuse rated for 600VAC and 300VDC. Eaton specifies an interrupting rating of 300 kAIC at 600VAC and 100 kAIC at 300VDC, along with a 10-second response time at 500% of rated current. When you select it correctly, install it with qualified electrical personnel, and operate it within its specified ratings, the LPJ-90SP is built to last as part of a properly designed and maintained electrical system.

Key Features and Benefits

• 90A Class J fuse: Provides a clear current rating and fuse class to match compatible equipment requirements.
• 600VAC / 300VDC rating: Eaton specifies the LPJ-90SP for applications requiring these AC or DC voltage ratings.
• Time-delay operation: Eaton specifies a response time of 10 seconds at 500% of rated current for this fuse.
• Current-limiting design: Eaton classifies the LPJ-90SP as a current-limiting fuse.
• Dual-element construction: Uses a dual-element configuration as specified by the manufacturer.
• Bolted blade connections: Uses a bolted blade end × bolted blade end configuration, an important detail when checking physical fit.
• Non-indicating: Eaton identifies this specific catalog number as a non-indicating fuse.

Where It Works Best

The Eaton Bussmann LPJ-90SP 90A Class J fuse is intended for compatible electrical equipment requiring its specific combination of 90A current rating, time-delay operation, current-limiting characteristics, dual-element construction, and high in-rush current motor protection. Those characteristics make it relevant when evaluating fuse requirements for compatible motor circuits and other equipment that requires the manufacturer's specified electrical ratings and physical configuration.
