Battery Isolator Switch - Metal Heavy Duty - 300Amp

Description Battery Cut-Off Switch 300A The 300A Battery Cut-Off Switch provides a reliable way to isolate battery power for safety, maintenance, or long-term storage. Designed for high-current applications, this switch is suitable for main battery and auxiliary battery isolation in 4x4 vehicles, caravans, boats, and power systems. It helps prevent battery drain, reduces fire risk during maintenance, and allows quick power shut-off in emergency situations. The switch is fitted with two M10 rear studs, allowing secure connection of heavy-gauge cables commonly used in high-current circuits such as winches, inverters, and dual battery systems. Solid copper terminals ensure efficient current flow and minimal voltage drop. A heavy-duty rotary knob provides positive ON/OFF operation, even when wearing gloves. The compact panel-mount design allows installation in battery boxes, engine bays, and electrical panels. Suitable for both 12V and 24V DC systems. 300A continuous current rating Battery isolation switch 2 × M10 rear-mounted studs for high-current cables Solid copper terminals Rotary ON / OFF operation Compact panel-mount design Suitable for 12V and 24V systems Current Rating: 300A (continuous) System Voltage: 12V / 24V DC Terminal Size: M10 studs (rear) Terminal Type: Accepts ring terminals
