Battery disconnect switch with a rated current of 240A, rated voltage of 12V, standby power consumption of 3mA, power-off threshold of 11.8V0.2V, and instantaneous current of 500A. This disconnect switch helps prevent car battery drain caused by long-term parking, electrical line aging, or leaving lights on. It helps preserve battery charge, providing effective protection and extending battery life. Smart 12V car disconnect switch automatically cuts off power after 120 seconds when battery voltage drops below 11.8V to conserve energy. When voltage rises above 13.5V, remote control is disabled to prevent accidental disconnection while driving; operation can then only be performed manually via the switch. Automatic cutoff feature disconnects power after 120 seconds if voltage falls below 11.8V. Remote control is disabled when voltage exceeds 13.2V to avoid unintended power interruption during operation, ensuring safe driving. Power control reverts to the manual switch button under these conditions. Helps protect the battery by preventing unnecessary discharge due to extended parking, faulty electronics, aging wiring, or leaving lights on. Contributes to maintaining battery health and prolonging service life. Color: As shown in picture. Material: Metal + Plastic. Package Contents: 1 x Remote Battery Disconnect Switch Kit.
