Bussmann LPJ-80SP Dual Element Time-Delay Fuse

The Bussmann LPJ-80SP is an 80-amp, 600-volt AC (300-volt DC) Class J dual-element time-delay fuse, designed to provide superior protection for industrial applications.

Key Features

• High Interrupting Rating: Capable of interrupting up to 300,000 amperes at 600 VAC and 100,000 amperes at 300 VDC, ensuring robust protection against high fault currents.
• Dual-Element Design: Incorporates separate overload and short-circuit elements, offering precise time-delay characteristics suitable for high inrush loads.
• Time-Delay Performance: Provides a minimum of 10 seconds delay at 500% of rated current, minimizing unnecessary openings due to temporary overloads and transient surges.
• Current Limitation: Limits the thermal and magnetic effects of short-circuit currents, protecting downstream components from potential damage.
• Selective Coordination: Maintains a consistent 2:1 ampacity ratio within the Low-Peak® fuse family, facilitating easy selective coordination and preventing electrical shutdowns from extending beyond the failed circuit.
• Compact Design: With dimensions of 1.13 inches in diameter and 4.63 inches in length, it offers a space-saving solution for equipment downsizing.

Applications

Ideal for use in branch circuit breaker panelboard mains, industrial control systems, machinery disconnects, and power panelboards. Its high interrupting capacity and time-delay characteristics make it suitable for protecting equipment with high inrush currents.

Compliance and Certifications

• UL Listed (Guide JDDZ, File E4273)
• CSA Certified (Class 1422-02, File 53787)
