It is designed to manage charging current from alternators up to 65 Amps, the range found on most outboards and many inboard engines, making it a compact solution for dual-battery bank management. A Start Isolation (SI) function temporarily isolates house loads from the engine circuit during engine cranking, protecting sensitive house electronics from the voltage sags and spikes that occur when the starter draws current. The m-ACR operates automatically at 12V DC or 24V DC and switches up to 65 Amps of contact current through Normally Open, Quick Connect terminals with tinned brass contacts for corrosion resistance in a marine environment. Its compact housing supports three mounting styles: surface mount, rear mount, or panel mount, giving installers flexibility in tight helm or engine bay spaces. The m-ACR is also offered as a module within a Custom 360 Panel for builders who want it integrated into a larger electrical panel layout. With a 10 second operating time and a 9.5V under-voltage lockout threshold, the relay is built to respond predictably to real charging conditions rather than momentary voltage fluctuations, helping protect both battery banks from unwanted cross-connection or premature isolation.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Blue Sea

It automatically combines two battery banks when the alternator is charging and isolates them again when charging stops, so the house bank cannot drain the starting bank between charges.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is the maximum alternator output the m-ACR 7601 can handle?\u003c\/strong\u003e It is designed to manage charging current from alternators up to 65 Amps, the output range found on most outboards and many inboard engines.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes the 7601 work on both 12V and 24V systems?\u003c\/strong\u003e Yes, the m-ACR 7601 operates automatically on 12V DC or 24V DC systems and is rated for up to 24 Volts maximum switching voltage.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is Start Isolation (SI) on the m-ACR?\u003c\/strong\u003e Start Isolation temporarily isolates house loads from the engine circuit during engine cranking, which protects sensitive house electronics from the voltage sags and spikes a starter motor can cause.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow is the Blue Sea Systems 7601 mounted?\u003c\/strong\u003e The compact m-ACR design supports three mounting styles: surface mount, rear mount, or panel mount, allowing it to fit a range of helm or engine bay layouts.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much current can the 7601 relay switch?\u003c\/strong\u003e The m-ACR 7601 has a maximum switching current of 65 Amps and a contact current rating of 65 Amps, using Normally Open, Quick Connect terminals.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat are the relay contacts made of on the 7601?\u003c\/strong\u003e The m-ACR uses tinned brass contacts, chosen for corrosion resistance in a marine electrical environment.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eAt what voltage does the m-ACR isolate the battery banks?\u003c\/strong\u003e The 7601 has a minimum switching voltage of 10.8 Volts and includes a 9.5V under-voltage lockout as part of its specification, so it isolates the banks once voltage drops rather than staying combined indefinitely.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow fast does the Blue Sea Systems 7601 respond to a change in charging state?\u003c\/strong\u003e The m-ACR has a 10 second operating time, allowing it to respond to real charging conditions rather than momentary voltage fluctuations.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does the Blue Sea Systems 7601 weigh?\u003c\/strong\u003e The m-ACR 7601 weighs 0.8 pounds.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCan the m-ACR 7601 be integrated into a larger electrical panel?\u003c\/strong\u003e Yes, in
