The Victron Energy Battery Switch ON/OFF 275A is a heavy-duty manual isolation switch for disconnecting battery banks in marine, vehicle and off-grid installations. Rated at 275A continuous, it gives a reliable way to isolate the battery from the load circuit for maintenance, storage or emergency shutdown.

Key features

• Current rating, 275A continuous, suitable for high-load 12V and 24V battery systems.
• Operation, simple ON/OFF switching for fast, positive isolation without tools.
• Weight, 232g, suitable for panel mounting in confined spaces.
• Contacts, designed to handle the high inrush currents typical of inverter and motor loads.
• Compatibility, fits standard busbar and battery main switch installations in marine, motorhome and off-grid setups.
• Identifiers, SKU VBS127010010, GTIN 8719076052258.

Product overview

A battery isolation switch disconnects the battery bank completely from the rest of the circuit. That matters during maintenance, when a vehicle or vessel is laid up, or if a fault develops. The 275A rating covers the sustained current draw of inverters, bow thrusters, winches and similar high-draw equipment.

There is no rotary selector or multiple positions to misread here. The switch is either open or closed, which helps when someone needs to isolate the system quickly. Its compact size makes it practical to mount in battery compartments, distribution panels or engine bays where space is tight.

Applications

• Battery isolation on narrowboats, sailing yachts and motorboats.
• Main battery disconnect on motorhomes, campervans and HGV auxiliary systems.
• Off-grid cabin and caravan battery banks needing manual isolation.
• Industrial and commercial DC systems requiring a lockout-capable main switch.
• Replacement or upgrade for existing battery main switches in Victron-based systems.

Installation notes

Fitting should be carried out by a competent electrician or qualified marine/vehicle electrical engineer. Check connections are correctly torqued and cable sizing suits the 275A rating before commissioning. Isolate all loads before fitting or removing the switch. Work on grid-connected or MCS-accredited solar systems should be done by a qualified installer.
