Parts Desk Insights

Best Use Case: Use this inline resettable breaker to protect a DC accessory circuit where a manual reset is preferred after an overload or fault. Ensure the copper (power-in) and silver (power-out) posts are connected to the correct sides of the circuit.

Common Issues: If the breaker trips repeatedly, confirm the accessory draw and wiring for shorts/overload before resetting. Also double-check correct terminal orientation (battery/power-in vs auxiliary/power-out) and inspect mating connections around the #10-32 studs to prevent poor contact.
