Auto Reset 30 Amp Breaker 12 - 24V
📝 Auto Reset 30 Amp Breaker 12–24V
The Auto Reset 30 Amp Circuit Breaker delivers robust, maintenance-free protection for higher-demand circuits in 12v and 24v electrical systems. Using a thermal automatic reset mechanism, it removes the need to replace blown fuses by restoring power automatically once a fault condition is cleared.
Built with a durable, rustproof housing and designed for flexible mounting, this breaker is well suited to automotive, marine, RV, and off-grid applications where reliable circuit protection is critical.
⭐ Essential Benefits
• Thermal auto-reset protection – automatically resets after overload, no fuse replacement required.
• 30 amp rating – ideal for compressors, fridges, pumps, and high-draw accessories.
• Suitable for 12v–24v systems – common automotive and marine voltages.
• Red vinyl protective cover – helps prevent corrosion and accidental shorts.
• Trip-free cycling design – maintains protection even during repeated faults.
• Compact, sealed construction – built for harsh operating environments.
⚙️ Functionality
This breaker monitors current flow and trips when the circuit exceeds 30 amps. Once the overload or short condition is removed, the breaker automatically resets, restoring power without manual intervention.
The unipolar, free-cycle trip design ensures consistent protection in vibration-prone and mobile installations.
