RED WOLF specializes in providing customers with high-quality auto parts and accessories. We constantly strive to innovate our product portfolio, focusing on function, design, and user convenience to deliver the most worthwhile offerings for our customers.

The 30-300A Circuit Breaker with Manual Reset is designed for DC 12-48V systems. This circuit breaker features a "Trip Free" design that prevents it from being held in the "ON" position during a fault current condition. All components meet the SAE J1171 external ignition protection requirements, ensuring safety and reliability. The robust 5/16"-18 terminals provide high-torque connections, accommodating up to 1/0 AWG lugs.

The manual reset switch allows for easy, hands-on control and operation. This makes the circuit breaker a good partner for protecting electrical systems.

The battery ring terminal ends are copper connectors that facilitate a reliable link between wiring cables and automotive electrical equipment, solar panel systems, and more. The braided wire cable sleeve helps organize and protect the wires, ensuring a clean, tidy, and safe installation.

Audio inline fuses and circuit breakers can be mounted on panels or firewalls to protect amplifiers from over-load current or voltage damage. The blade fuse box allows each fuse to be connected to various electrical circuits, such as ceiling lights, headlights, fog lights, tail lights, rocker switches, and toggle switches.

Our 30-150A circuit breakers are designed to meet your needs. The available options include 30A, 40A, 50A, 60A, 80A, 100A, and 150A models, all with a 12V-48V operating voltage and panel/surface mount design. These standard circuit breakers feature a manual reset function and come with installation accessories.

For higher amperage requirements, we offer 60A, 80A, 100A, 150A, 200A, 250A, and 300A circuit breakers. These models also have a manual reset function and include installation instructions.

The 300A circuit breaker with manual reset is a versatile solution for various DC systems. The visible reset lever indicates the open condition, and the unique push-button reset allows it to function as a master disconnect kill switch. This circuit breaker can protect your trolling motor, prevent excessive current, and stop power surges from damaging the amps. Suitable for 12V-48V DC systems, it is designed to shield the system from over-current due to high power draw, short-circuits, wiring issues, or equipment faults.

Made with professional-grade materials, the circuit breaker features a pure copper screw and a thermal plastic UL-rated 94V0 housing. It is easy to operate and can be mounted on a panel or firewall. The 300A circuit breaker is ideal for applications in boats, marine, RVs, yachts, batteries, trailers, buses, trucks, ATVs, winches, battery chargers, and DC sound amplifier systems.
