The Victron Energy Battery Switch ON/OFF 275A (VBS127010010) is a heavy-duty battery disconnect switch designed to isolate batteries from DC loads and charge sources in marine, automotive, and off-grid installations. Rated for 275A continuous current with a 450A one-minute rating and 1200A cranking rating, this switch handles the demands of large battery banks and high-current systems up to 48V. The tin-plated copper terminals ensure low resistance and excellent conductivity. The switch can be surface or panel mounted, providing installation flexibility. The unique ergonomic knob is removable for security and isolation purposes — ideal for preventing unauthorised use or ensuring complete disconnection during maintenance. Meeting the ISO 8846 Ignition Protection standard, the switch is safe for use in engine rooms and other environments where flammable gases may be present. Typical applications include isolating house batteries on boats and motorhomes, disconnecting solar battery banks, emergency battery disconnection, and paralleling house and starter batteries in emergencies.
