The Victron Energy Battery Switch ON/OFF 275A is a premium-grade manual DC disconnect switch engineered to safely isolate batteries or entirely de-energize power systems operating at 12V, 24V, or 48V DC. With a continuous current rating of 275A and a peak capacity of up to 1500A for 1 second, this switch ensures robust control and ultimate protection for power installations of any complexity.
Core Advantages of the Battery Switch ON/OFF
- Continuous current rating: 275A at 12/24/48V
- Transient current capacity: up to 1500A (1 sec) — safely handles inverter inrush currents
- Compact form factor featuring a rotary dial
- True mechanical circuit separation — guarantees maximum safety
- Tamper-proof design — removable knob prevents accidental switching
- Flexible installation: suitable for both panel and surface mounting
- Seamless compatibility with all Victron Energy DC ecosystems
Technological Features
- Overload tolerance — designed to work in tandem with fuses to prevent damage to cables, battery banks, and sensitive electronics during overcurrent events.
- Extremely low contact resistance — making it highly suitable for applications involving massive starting currents.
- Heavy-duty build — engineered to sustain high current loads in demanding, high-power systems.
Application Scenarios
- Isolating battery banks prior to routine maintenance or servicing
- Emergency power disconnection for inverters, chargers, or main DC busbars
- Mobile applications — RVs, camper vans, and utility vehicles
- Marine environments utilizing high-capacity battery arrays
- Stationary and off-grid solar systems requiring a reliable manual disconnect
