Battery disconnect switch 12V/24V/48V – Main switch ON/OFF 200A

Ensure the safety of your installation by cutting the power with one gesture. This disconnect switch 12–48 V delivers 200 A continuously (up to 1250 A at start) and uses M10 tinned copper terminals for durable conductivity. It limits parasitic discharge during parking/wintering and facilitates maintenance. Insulating rear cover, removable side plates for clean cable routing. Recommended on the negative pole side with an appropriate fuse/circuit breaker. Perfect for car, boat, camper, battery banks.

Master Switch for boat, car, truck, RV, UTV/ATV – Quick isolation & safety

Cut the power in 1/4 turn. Protect your batteries, prevent current leaks, and secure your interventions on any 12 to 48 V DC system.

Key features

• Universal 12–48 V DC: ideal for car, boat, RV, van, bus, off-grid.
• High power: 200 A continuous, 455 A intermittent, 1250 A cranking (starting).
• Robust M10 (10 mm) terminals with nuts/insulating rear cover.
• Very readable ON/OFF: ON (green), OFF (red) — error-proof.
• Safety: quickly isolates the battery for maintenance, winterizing, or in case of emergency.
• Durable materials: tinned red copper (excellent conductivity, anti-oxidation) & ABS/nylon.
• Simple installation: 4 removable side plates for cable passage, stainless steel screws included for mounting.
• Can operate alone or be locked in series with a second switch.

The ON/OFF battery switch 12–48 V allows you to instantly isolate the electrical circuit to secure your interventions, prevent parasitic discharge during long parking, and protect your equipment. Its tinned copper core ensures low contact resistance and excellent durability, while its rear cover protects the terminals from short circuits. The color indications ON/OFF prevent any confusion during use.

Pro recommendation: install it on the negative pole side (lower current, reduced risk of arcs).

Installation tips

1. Disconnect all power sources before intervention.
2. Preferably mount on the negative terminal of the battery.
3. Use M10 lugs and a cable section suitable for max current and line length.
4. Torque-tighten, check for no play; insulate exposed parts.
5. Install in a dry and ventilated box.
6. Test ON/OFF, then check for no abnormal voltage drop under load.
