Victron Energy 275A Battery Switch: The Professional Standard for System Isolation

The Victron Energy 275A ON/OFF Battery Switch is a heavy-duty master disconnect designed for absolute reliability in marine, RV, and off-grid solar systems. Rated for a continuous 275A current and compatible with systems up to 48V, it allows you to safely isolate battery banks from DC loads or charging sources during maintenance, emergencies, or storage to prevent parasitic drain.

Built for the harshest environments, this switch meets the ISO8846 Ignition Protection standard, making it safe for use in gasoline-powered engine rooms. Its unique ergonomic knob design is not only easy to operate with gloved hands but is also completely removable, acting as a lockout/tagout safety feature to prevent unauthorized system activation.

Key Safety & Installation Features:

• Versatile Mounting Options: Supports both surface mounting and rear panel mounting, providing maximum flexibility for clean dashboard or enclosure installs.
• 4-Way Cable Access: Features four easily removable side panels, allowing for simplified cable routing from any direction without additional drilling.
• Corrosion-Resistant Hardware: Equipped with M10 (3/8") tinned copper studs and nuts for maximum conductivity and longevity in humid or salty marine conditions.
• Customizable Labeling: Includes a 16-piece interchangeable label sticker sheet, allowing you to clearly mark the switch's function (e.g., "House," "Inverter," "Start").
• High Peak Ratings: Beyond its 275A continuous rating, it handles a 1-minute intermittent load of 455A and a 10-second cranking surge of 1250A.

Technical Tip: When installing, ensure all connections are torqued to 8Nm (70 lbf-inch). For 48V systems, this switch is an excellent choice for isolating an inverter/charger from the main battery bus.
