20A 12VDC Chassis Mount Auto-Reset Circuit Breaker – JAYCAR

A blown fuse in your solar panel run or under the bonnet means hunting for a spare, cutting wire, and praying you didn't nick a ground. This 20A thermal breaker bolts straight to a flat surface, trips when current spikes past what it should, and resets itself once things cool down. No fuse box. No hunting. Bolt it in and move on

• Single-pole thermal auto-reset — no fuse replacement needed
• Chassis mount with bolt-down holes for any flat parallel surface
• Suited to automotive wiring and solar panel circuits
• Protects against overcurrent without cutting your run
