Sierra FS82040 ANL Fuse 250 Amp Marine Ignition Protected

The Sierra FS82040 is a heavy-duty 250 amp ANL (Automotive Nickel Link) fuse designed for marine electrical systems and high-current applications. ANL fuses are commonly used to protect primary power distribution circuits, battery banks, and inverter systems in boats, RVs, and other marine and automotive applications.

Key Features:

• Ceramic body construction provides superior insulation and heat resistance
• Brass, gold-plated contact elements ensure excellent electrical conductivity and corrosion resistance
• Ignition Protected rating meets ISO 8846 marine safety standards
• 100% current rating for minimum 4 hours of continuous operation
• 150% current rating (375 amps) for minimum 60 seconds before activation
• 200% current rating (500 amps) for minimum 15 seconds before activation

This fuse is engineered to provide reliable overcurrent protection in demanding marine environments where moisture, vibration, and temperature extremes are common. The gold-plated brass elements resist corrosion while maintaining optimal electrical contact, and the ceramic body withstands high temperatures during overload conditions. Ideal for protecting batteries, inverters, windlasses, and other high-amperage equipment on boats and marine vessels.
