LPJ-12SP - 12 Amp Fuse

LPJ-12SP - 12 Amp Fuse

When your replacement fuse must match the application, the small details matter as much as the amp rating. The Eaton Bussmann series LPJ-12SP is a 12A Class J time-delay, current-limiting fuse rated for 600VAC and 300VDC. For maintenance teams, electricians, and facility personnel working with equipment that requires this particular Class J configuration, those specifications make it easier to check the fuse against the existing application before installation. The LPJ-12SP is also CE-marked and RoHS-compliant. When correctly selected, installed, and operated within its specified ratings, it's built to last as part of a properly maintained electrical system.

Key Features and Benefits

• 12A Class J configuration: Designed for compatible equipment requiring a 12-amp Class J fuse.
• Time-delay operation: Helps accommodate temporary current surges associated with equipment startup and other normal inrush conditions.
• High-inrush-current motor protection: Eaton identifies the LPJ-12SP for applications requiring high-inrush-current motor protection.
• Current-limiting fuse design: Provides the specified current-limiting characteristics when applied within its ratings.
• Dual-element construction: Uses two elements in its time-delay operating design.
• 600VAC and 300VDC ratings: Clearly defined AC and DC voltage ratings help simplify application and replacement checks.
• Specified time-delay response: Eaton lists a response time of 10 seconds at 500% of the fuse's rated current.
• Compact ferrule connection: The ferrule-to-ferrule design provides a defined physical configuration for compatible fuse holders and equipment.

Where It Works Best

The Eaton Bussmann LPJ-12SP 12A fuse suits compatible commercial and industrial electrical equipment designed for a Class J, 12A, time-delay, current-limiting fuse with ferrule-end connections. Its time-delay characteristics make it particularly relevant where normal startup conditions can produce temporary inrush current, including properly specified motor applications.
