Waterproof Circuit Breaker 300 A Resettable 7.4 x 4.9 x 4.4 cm Manual Reset For Car Audio and Boat Short Circuit and Overload Protection
You already have the maximum available quantity in your cart.
The waterproof circuit breaker 300 A is a resettable replacement for a traditional fuse, protecting wiring and connected devices from short circuits and overloads in cars, boats, and audio installations. When the current exceeds 300 A, the breaker automatically disconnects the circuit, and once the fault is cleared, it can be reset manually using the reset button, eliminating the need to source and replace blown fuses. The robust waterproof casing marked WATERPROOF resists moisture and splashes, making it suitable for exposed environments such as engine compartments or decks. Compact dimensions of 7.4 x 4.9 x 4.4 cm and screw terminals facilitate installation to the battery, amplifier, or power circuit. Additionally, the breaker is designed as ignition protected for use in environments with fuel vapours.

The circuit breaker is a practical solution for protecting power circuits where frequent fuse replacements would be inconvenient. Thanks to the resettable button, once the cause of the fault is removed, the circuit can be easily restored without any tools or spare parts. The waterproof and ignition protected design makes it ideal for demanding environments on water and in engine compartments. Screw terminals and mounting holes allow for secure and safe installation of heavier wires. It is particularly useful for automotive amplifiers and audio systems, as well as on boats, ATVs, and in other 12 V installations.
