One switch terminal connects to the battery-positive conductor, and the other connects to the positive conductor feeding the selected load circuit, alternator circuit, or second battery. Final switch location, fuse placement, and cable routing should follow the requirements of the complete RV, marine, vehicle, or off-grid system.\n        \u003c\/p\u003e\n      \u003c\/details\u003e\n\u003cdetails style=\"background:#FFFFFF; border:1px solid #E2E8F0; border-left:5px solid #5EBB46; border-radius:10px; padding:18px;\"\u003e\n        \u003csummary style=\"cursor:pointer; color:#1A202C; font-weight:700; font-size:16px; line-height:1.4;\"\u003e\n          Can I use the Victron 275A battery switch in a 48V system?\n        \u003c\/summary\u003e\n        \u003cp style=\"margin:14px 0 0 0; color:#2D3748;\"\u003e\n          Yes. Victron states that the Battery Switch ON\/OFF 275A is suitable for battery systems up to 48V.

The switch is rated for 275A continuous DC current. Do not size it from inverter wattage alone; confirm the inverter manufacturer's DC-current requirements and apply the appropriate engineering and regulatory margins.\n        \u003c\/p\u003e\n      \u003c\/details\u003e\n\u003cdetails style=\"background:#FFFFFF; border:1px solid #E2E8F0; border-left:5px solid #2E91E5; border-radius:10px; padding:18px;\"\u003e\n        \u003csummary style=\"cursor:pointer; color:#1A202C; font-weight:700; font-size:16px; line-height:1.4;\"\u003e\n          What are the short-duration and cranking ratings?\n        \u003c\/summary\u003e\n        \u003cp style=\"margin:14px 0 0 0; color:#2D3748;\"\u003e\n          Victron publishes a 1,250A peak cranking rating for 10 seconds. Its current manual lists a 455A five-minute DC rating, while the separate product data sheet labels 455A as a one-minute rating.
