1 x 150A automotive circuit breaker, waterproof with manual reset for 12V-48V circuits, suitable for cars, boats and audio systems

This 150A DC circuit breaker is designed to effectively protect 12V to 48V electrical circuits in demanding mobile environments. Made from high-quality conductive alloy, it ensures low contact resistance and consistent thermal stability, even under prolonged load. Its IP67-rated waterproof housing makes it suitable for humid or saline environments, such as those found on boats, marine vehicles, or motorhomes. Manual reset is tool-free and requires only a single action, eliminating service interruptions associated with fuse replacement. Installation is quick and easy on panels or metal structures, without modifying the original wiring. It is frequently used to protect high-power audio amplifiers, onboard monitoring systems, lithium battery chargers, or high-intensity LED lighting—always in compliance with applicable French electrical safety standards (NF C 15-100 for fixed installations, EMC best practices for vehicles).
