Auto Reset 20 Amp Breaker 12 - 24V
📝 Auto Reset 20 Amp Breaker 12–24V
The Auto Reset 20 Amp Circuit Breaker provides reliable, maintenance-free protection for higher-load circuits in 12v and 24v electrical systems. Using a thermal automatic reset mechanism, it eliminates 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 ideal for automotive, marine, RV, and off-grid applications where dependable circuit protection is essential.
⭐ Essential Benefits
• Thermal auto-reset protection – automatically resets after overload, no fuse replacement required.
• 20 amp rating – suitable for fridges, compressors, and higher-draw accessories.
• Suitable for 12v–24v systems – common automotive and marine voltages.
