LPJ-175SP - 175 Amp Fuse

LPJ-175SP - 175 Amp Fuse

The Eaton Bussmann series LPJ-175SP is a 175A Class J time-delay, current-limiting fuse for your compatible commercial and industrial electrical equipment, including applications with expected temporary motor inrush current. Rated 600VAC and 300VDC, the LPJ-175SP has manufacturer-specified interrupting ratings of 300 kAIC at 600VAC and 100 kAIC at 300VDC. Its dual-element construction works with its time-delay characteristics, with Eaton specifying a response time of 10 seconds at 500% of rated current.

Key Features and Benefits

• 175A Class J configuration: Designed for compatible electrical equipment requiring a 175-amp Class J fuse with the LPJ-175SP's specified characteristics.
• Time-delay operation: Helps accommodate temporary inrush currents that can occur during normal equipment or motor startup.
• High-inrush-current motor protection: Eaton identifies this model for applications requiring high-inrush-current motor protection.
• Current-limiting fuse design: Provides the specified current-limiting characteristics for electrical systems designed to use this type of overcurrent protection.
• Dual-element construction: Uses two elements as part of the fuse's time-delay design.
• 600VAC / 300VDC ratings: Clearly defined AC and DC voltage ratings make it easier to determine whether the fuse matches the intended system.
• 10-second response at 500%: Eaton specifies a response time of 10 seconds at 500% of rated current.
• Non-indicating design: The LPJ-175SP does not incorporate a built-in fuse-status indicator.
