Blue Sea Automatic Charging Relay 12/24 Volt, Battery Isolator, Ignition-Proof and Hermetically Sealed

Automatically combines batteries when charging, isolates batteries when discharging and when starting engines.

• Protects sensitive electronics by temporarily isolating house loads from the engine circuit during engine starting.
• Designed for 12 or 24 volt systems.
• 12/24 volt voltage input with automatic range selection.
• Hermetically sealed contacts/vapor-tight.
• Ignition-protected – safe for installation on board gasoline-powered boats.
• Supports high power generators up to 120 amps.
• Dual sensing.

• Start isolation allows the house loads to be temporarily isolated from the engine circuit during engine start-up to protect sensitive electronics from voltage drops and spikes.
• The remote LED indicates ACR conditions remotely – requires an optional LED.
