The MT005 is a voltage-controlled battery isolator designed for 12V DC dual-battery systems. It closes at a 13.3V cut-in threshold and opens again at 12.7V, holding the open state for a 5-second delay so a brief voltage dip under load does not split the battery banks unnecessarily.
In practice, this means the auxiliary battery is charged whenever the alternator or charger is working, and is separated from the starting battery once charging has finished and surface voltage has settled. The starting battery stays reserved for cranking — even if a fridge, lights or electronics have been running all night on the house side.
Current handling is rated at 140A continuous and 160A for up to 60 seconds, covering the charge and combined accessory demand of most boats, campers and dual-battery vehicles while keeping a clear margin for short peaks.

Plan the cable route first — the unit sits between the two positive feeds and picks up a common ground:
Short voltage dips happen every time a pump, winch or fridge compressor starts. The delay stops the relay from separating the banks during those moments, which would otherwise cause repeated chatter.
No — this model is set for 12V DC with a 13.3V cut-in. Ask us about higher-voltage alternatives before ordering.
No. Once charging stops and voltage settles to the cut-out level, the contacts open and the two banks are separated.
Size cable for 140A continuous with a margin, and fit a fuse or breaker at the battery end of the auxiliary feed.
Yes — minimum order is 1 piece, and we build to customer samples or technical drawings when a new design is needed.
