LPJ-9SP - 9 Amp Fuse

LPJ-9SP - 9 Amp Fuse

Choosing the right fuse takes more than matching the amp rating. The Eaton Bussmann series LPJ-9SP is a 9A Class J time-delay, current-limiting fuse rated for 600VAC and 300VDC. Eaton specifies interrupting ratings of 300 kAIC at 600VAC and 100 kAIC at 300VDC, along with dual-element construction and a ferrule-end × ferrule-end connection. The manufacturer also identifies high in-rush current motor protection as a special feature, an important consideration when evaluating the fuse for compatible motor applications. When properly selected, installed by your qualified electrical personnel, and operated within its specified ratings, the LPJ-9SP is built to last as part of a correctly designed and maintained electrical system.

Key Features and Benefits

• 9A Class J configuration: Gives electricians and maintenance teams a precise amperage and fuse-class combination to match against equipment requirements.
• 600VAC and 300VDC ratings: Supports compatible AC or DC applications requiring the manufacturer's specified voltage ratings.
• Time-delay characteristics: Designed with time-delay operation; Eaton specifies a response time of 10 seconds at 500% of rated current.
• Current-limiting fuse: Eaton classifies the LPJ-9SP as current-limiting, an important characteristic to confirm when selecting circuit protection.
• Dual-element construction: Uses the manufacturer's specified dual-element configuration.
• High in-rush current motor protection: Eaton identifies this as a special feature for compatible motor applications.
• Ferrule-end connection: Uses a ferrule-end × ferrule-end configuration to match compatible fuse holders and equipment.
• Non-indicating designation: Eaton's dedicated fuse-indicator specification identifies the LPJ-9SP as non-indicating.

Where It Works Best

The Eaton Bussmann LPJ-9SP 9A Class J fuse is intended for compatible electrical equipment that requires its specific combination of 9A capacity, 600VAC / 300VDC ratings, time-delay operation, current-limiting characteristics, dual-element construction, and ferrule-end connections. Eaton's stated high in-rush current motor protection is also relevant when evaluating this fuse for compatible motor applications.
