Sierra FS82070 ANL Fuse 400 Amp Ignition Protected

The Sierra FS82070 is a heavy-duty 400 amp ANL (American National Standard) fuse designed for high-amperage marine and automotive electrical systems. This ignition-protected fuse provides reliable overcurrent protection for critical power distribution applications including battery banks, inverters, and high-output alternators.

Key Features:

• Ceramic body construction provides superior heat resistance and electrical insulation
• Brass elements with gold plating ensure excellent conductivity and corrosion resistance
• Ignition Protected design meets ISO 8846 marine safety standards
• 100% rated for minimum 4 hours continuous operation at rated amperage
• 150% rated for minimum 60 seconds overload protection
• 200% rated for minimum 15 seconds fault response

ANL fuses are commonly used in marine electrical systems, RVs, and high-performance automotive applications where space-efficient, high-amperage circuit protection is required. This fuse is designed to fit standard ANL fuse holders and provides reliable protection while maintaining low voltage drop during normal operation.
