Power Switch Feature: Magnetic Lock Feature: The remote battery disconnect switch utilizes an innovative relay system based on magnetic principles to control the connection and disconnection of circuits. With a standby current of just 0.015A, it significantly enhances energy efficiency, making it an ideal solution for optimizing vehicle power management. Versatile Compatibility: Designed for 12V DC power vehicles, this automatic power shut off switch is compatible with a wide range of vehicles including most cars, trucks, RVs, buses, and trailers, specifically those with an engine displacement of less than 3.0. Intelligent Automatic Disconnection: The car remote battery cut off switch features an automatic disconnection function that activates if the battery voltage drops below 11.8V. It automatically cuts off power within 120 seconds to conserve energy. Conversely, when the voltage exceeds 13.2V, the remote control becomes inactive to prevent accidental power cuts while driving, ensuring manual switch control only. Remember to turn off the engine before installation to a safe and efficient setup process. Enhanced Battery Protection: By leveraging this leakage protection device, you can avoid unnecessary battery drainage caused by prolonged parking periods, well-functioning electronics, wiring degradation, or forgetting to turn off the lights. Working voltage: 12V Passing current: 260A Standby current: 0.015A Instantaneous current: 100A.Attention: When installing this product, please check whether the engine is turned off.The inspection switch is also a manual power-off switch.
