Car Circuit Breaker, 12V-48V Circuit Breaker-Fuse Holder, Waterproof Circuit Breaker with Waterproof Car Manual Reset, for Motor Auto Marine Boat Bike Stereo Audio(20A)

【Good Conductivity】: Bakelite has high mechanical strength, good insulation properties, heat resistance and corrosion resistance, and zinc alloy has good electrical conductivity.

【Practical Function】: In-line circuit breaker fuses for car audio are available in DC 20A; 40A; 60A; 80A. High current overload protection. Protects the car circuit against burnt out loads (devices) due to excessive current, protects the trolling motor from electrical damage.

【Easy to Use】: Three operating modes: automatic disconnection, manual disconnection, automatic disconnection + switch. Easy to reconnect, just push the red part back to connect the circuit breaker. Temperature resistant and high voltages, rated at 32 V DC. 48 V DC maximum.

【Disconnection Protection】: When the current reaches the disconnection value, the long handle will automatically open to cut off the power supply, short circuit conditions generally jump open, such as troubleshooting, then squeeze the long handle back to its original position to form an access path.

【Application】: Car Audio Resettable Fuse Box Switch with Silicone Sleeve is widely used in auxiliary and accessory circuits of trucks, buses, caravans and boats. Mounted on a panel or firewall, it prevents power surges from damaging amplifiers and the fuse does not need to be replaced.
