LPJ-225SP - 225 Amp Fuse

LPJ-225SP - 225 Amp Fuse

When a piece of electrical equipment calls for a specific fuse, close enough isn't good enough. The Eaton Bussmann series LPJ-225SP is a 225A Class J time-delay, current-limiting fuse rated for 600VAC and 300VDC, with manufacturer-specified interrupting ratings of 300 kAIC at 600VAC and 100 kAIC at 300VDC. For electricians and maintenance teams matching an existing fuse, these details provide useful checkpoints before installation. The LPJ-225SP is also CE-marked and RoHS-compliant. When you select, install, and operate it within its specified ratings, this Eaton Bussmann Class J fuse is built to last as part of a properly designed and maintained electrical system.

Key Features and Benefits

• 225A Class J configuration: Designed for compatible electrical equipment requiring a 225-amp Class J fuse with the LPJ-225SP's specified electrical and physical characteristics.
• Time-delay operation: Eaton specifies a response time of 10 seconds at 500% of rated current, an important characteristic to verify when the application requires time-delay protection.
• High-inrush-current motor protection: The manufacturer identifies the LPJ-225SP for applications requiring high-inrush-current motor protection.
• Current-limiting design: Provides the current-limiting characteristics specified for electrical systems designed to use this type of fuse.
• Dual-element construction: Uses a dual-element configuration as part of the fuse's design.
• 600VAC and 300VDC ratings: Clearly defined AC and DC voltage ratings help technicians determine whether the fuse matches the intended electrical system.
• Bolted blade connections: Features a bolted blade-to-bolted blade configuration for compatible fuse-mounting arrangements.
• Non-indicating design: The LPJ-225SP does not incorporate a built-in fuse-status indicator.

Where It Works Best

The Eaton Bussmann LPJ-225SP 225A Class J fuse is intended for compatible commercial and industrial electrical systems requiring its combination of time-delay operation, current-limiting characteristics, dual-element construction, and high-inrush-current motor protection. It's especially relevant for compatible motor applications where temporary starting current is expected and the equipment calls for a fuse with these specific characteristics.
