Battery Disconnect Switch 12V–48V Marine

A heavy-duty battery disconnect switch for 12V to 48V DC systems. Isolates power from your battery when your vehicle, RV, or boat is not in use, preventing unwanted power drain and protecting your electrical system.

Constructed with ABS plastic housing and durable bolted terminals. The switch features two positions (On/Off) and delivers 275A continuous current at 12V DC, with 455A intermittent and 1250A momentary capacity. Copper terminal studs measure 3/8″ (10mm) and are simple to install on most vehicles.

Designed for universal application across cars, vehicles, RVs, boats, and electrical equipment. The rear cover insulates terminals against short circuits, and the unit can stand alone or be locked together with other switches for multi-battery setups.

Installation requires standard tools and fits most aftermarket battery locations. Operates via a straightforward On/Off mechanism for reliable manual control.

Check your vehicle’s electrical specifications before ordering to confirm voltage compatibility within the 12–48V range.
