Blue Sea Automatic Charging Relay ML-ACR 24 V DC 5

Regular price €324,34

Tax included.

Two battery banks, one smart relay: The Blue Sea ML-ACR automatically connects your house and starter batteries for charging and reliably separates them during discharge – so you'll never again be stuck with a dead starter battery. The Magnetic Latch (ML) technology maintains the switch state permanently with minimal power consumption, and the included Contura manual switch gives you full manual control at all times.

Tip: Always use the manual switch's Lock-Off function during maintenance work on the onboard electrical system – this mechanically locks the relay and prevents it from accidentally closing, even if voltage is inadvertently present.
