30 Amp Resettable Circuit Breaker

The QUICKCAR RACING PRODUCTS 30 Amp Resettable Circuit Breaker (Part No. 50-9730) is a compact electrical protection component designed for high-performance automotive and mobile power systems. This resettable circuit breaker serves as a critical safety device, interrupting electrical flow when current exceeds the 30-amp threshold and automatically restoring power once the fault condition clears—eliminating the need for replaceable fuse cartridges common in older installations.

At 30 amps, this breaker handles moderate to heavy continuous loads typical in auxiliary lighting circuits, winch systems, and secondary power distribution on trucks, tactical vehicles, and mobile command platforms. The resettable design reduces field maintenance burden—no spare fuses required, and operators can restore functionality immediately without parts replacement. Measuring 2.7 x 0.95 x 3.2 inches with a lightweight 0.07 lbs profile, installation footprint is minimal, making it suitable for compact dash-mount or engine-bay configurations. QUICKCAR's circuit breakers are engineered for reliability under the thermal and vibration stress of off-road and motorsport environments where conventional automotive electrics face repeated shock loads.

This is the component of choice for off-road recovery teams, mobile tactical units, and motorsport enthusiasts upgrading electrical architecture beyond factory specifications. Whether protecting a secondary battery circuit, fuel pump upgrade, or auxiliary accessory bus, the 30-amp rating provides adequate protection for single-load or multi-load distribution without over-sizing. The resettable mechanism operates without user intervention—a trip indicates an overcurrent event requiring fault diagnosis, not a quick-swap fix that masks underlying wiring problems.
