When a vehicle or vessel sits idle, parasitic drain can sap a battery and complicate startup. This high-current disconnect switch sits in the negative battery line and lets you cut power with a simple 90-degree turn, preventing leakage, reducing corrosion risk, and giving you confidence in any storage or emergency scenario.\u003c\/p\u003e \u003cp\u003eEngineered for tough conditions, it supports 12–60V DC systems and delivers continuous operation up to 300A, with a powerful instantaneous surge of 1000A and an overload threshold of 200A. Built from a durable blend of copper, iron, rubber, and plastic, it’s designed for long life (up to 100,000 cycles) and dependable performance in demanding environments. Its universal design makes it suitable for ATVs, trailers, off-road vehicles, RVs, trucks, heavy equipment, boats, and more. Installation is straightforward on the negative wire, but you’ll need one extra wire for a clean, secure setup. Note that installation guides are not included, and professional installation is recommended to avoid damage or warranty issues.\u003c\/p\u003e \u003cp\u003eAll electronic and mechanical equipment, devices and machines sold by InterCyprus to EU countries are CE certified and carry a two year warranty.\u003c\/p\u003e \u003ch3\u003eBenefits \u0026amp; Tips\u003c\/h3\u003e\n\u003cul\u003e \u003cli\u003e\n\u003cstrong\u003eSafeguard battery life during storage:\u003c\/strong\u003e Isolate the negative terminal to prevent parasitic drain and keep your battery ready for when you need it.\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003eFast, secure power-off:\u003c\/strong\u003e The 90° rotary action allows quick disconnection in everyday use or during maintenance.\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003eVersatile for multiple vehicles and gear:\u003c\/strong\u003e Ideal for ATVs, trailers, RVs, boats, and heavy equipment—just verify the size and fit for your setup.\u003c\/li\u003e\n\u003c\/ul\u003e \u003ch3\u003eProduct specifications\u003c\/h3\u003e\n\u003cul\u003e \u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e PQY\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003eItem Type:\u003c\/strong\u003e Battery Switch \/ Master Isolator \/ Circuit Breaker Power Switch\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Copper \/ Iron \/ Rubber \/ Plastic\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003eColor:\u003c\/strong\u003e As Picture\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003eRated current:\u003c\/strong\u003e 300A (12V)\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003eInstantaneous current:\u003c\/strong\u003e 1000A (12V)\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003eOverload current:\u003c\/strong\u003e 200A\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003eWorking voltage:\u003c\/strong\u003e 12–60VDC\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003eRotary degree:\u003c\/strong\u003e 90°\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003eLife time:\u003c\/strong\u003e 100,000 cycles\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003eInstallation principle:\u003c\/strong\u003e Installed on the negative wire of the electrical system (prepare one more wire than the original system)\u003c\/li\u003e \u003cli\u003e\n\u003cstrong\u003eCompatibility:\u003c\/strong\u003e Universal (check size\/type to match your needs)\u003c\/li\u003e\n\u003c\/ul\u003e \u003ch3\u003ePackage includes:\u003c\/h3\u003e\n\u003cul\u003e \u003cli\u003e1x Mount Kit.
