300 A 12-48 V DC Circuit Breaker with Waterproof Cover

High Quality Material: The automotive resettable circuit breaker is made of high-quality alloy material. The alloy material is hard and not easily deformed, and can withstand slight collisions and compressions during daily use. The alloy itself has good stability and can maintain structural integrity for a long time in the face of complex conditions that may be encountered during car driving, allowing the product to maintain stable performance in different usage scenarios.
Widely Used: This product measures 3.31 inch in length, 2.72 inch in width, and 1.61 inch in height. It is suitable for high current scenarios of vehicles such as cars, ships, boats, RVs, caravans, tractors, as well as speakers, horns, dual battery isolators for cars, winches, and other equipment. It is also applicable to auxiliary DC electrical systems.
Easy Installation: Please disconnect the vehicle or equipment power supply before installation, and choose a convenient location to fix the circuit breaker. Then connect the input wire to the "IN" terminal and the output wire to the "OUT" terminal. After confirming that the wiring is secure, restore the power supply and press the reset button to use it normally. It is easy to operate and can effectively ensure circuit safety.
Manual Reset Function: This product is a high current thermal trip circuit breaker with a manual reset switch, suitable for auxiliary DC electrical systems. When the current reaches the predetermined value, the circuit can be automatically disconnected to complete overcurrent protection. After troubleshooting, the reset switch can be manually pressed to restore use without frequent replacement of fuses.
Circuit Protection: This product also has overvoltage protection to prevent damage to electrical equipment caused by high voltage. Residual current protection to avoid safety hazards caused by leakage. Overcharge protection effectively protects devices such as batteries from the effects of overcharging, ensuring comprehensive safety of circuits and electrical equipment.
