• Reliable Protection: The tool automatically interrupts electrical flow during overloads or short circuits, helping to avoid harm to the battery from incorrect charging practices. It also includes thermal monitoring that responds when surrounding temperatures rise beyond safe levels, offering added protection to the power source
• Quality Materials: The housing of the overcurrent protector is constructed from durable plastic, offering reliable insulation and resistance to corrosion for extended service. Inside, copper bolt terminals ensure efficient electrical conduction and strong durability against wear
• Available Options: The waterproof circuit breaker is designed to resume normal function on their own once the issue is resolved, without requiring user action. We provide four current capacity options—AR-20A, AR-30A, AR-40A, and AR-50A—allowing you to pick the model that best matches your electrical requirements
• Operating Method: Begin by mounting the auto-reset circuit breaker near the battery and electrical device it's meant to support. Next, attach the wiring to the positive and negative terminals, then fasten nuts onto those terminals. Once everything is in place, restore power to the circuit to verify that the protector operates as intended
• Wide Applicability: The AR overcurrent protector operates within a 12V to 24V DC voltage range, making it versatile for various uses. It can be effectively deployed in vehicle electrical setups, solar power installations, boat electrical systems, home appliances, and other industrial equipment
