AFI 2100 Marine Battery Selector Switch 230 Amp Continuous

The AFI 2100 Battery Selector Switch is a heavy-duty marine battery switch designed for reliable power management on boats and marine vessels. This robust switch allows you to select between multiple battery banks or turn the system off completely, making it essential for managing onboard electrical systems.

Key Features:

• Rated at 230 amps continuous duty, 345 amps momentary for high-capacity electrical systems
• Alternator Field Disconnect (AFD) technology protects your alternator from damage when switching positions, even when selecting "OFF"
• Durable red polycarbonate case resists corrosion and UV damage in harsh marine environments
• 3/8" cable lug terminals accommodate standard marine battery cables
• Four-position selector: Battery 1, Battery 2, Both, and Off

This battery switch is ideal for boats with dual battery systems, allowing you to isolate batteries for starting, combine them for heavy loads, or disconnect all power when the vessel is not in use. The AFD feature ensures safe switching without risk of voltage spikes that can damage sensitive alternator components.
