Keep the electrical circuits on your Scion or Toyota protected from damaging overcurrent with the Standard Ignition Circuit Breaker FH49. It drops in as a direct-fit replacement for the 2008-2014 Scion xD and the 2006-2014 Toyota Yaris, restoring factory-style overcurrent protection to the circuit it serves.

  • Overcurrent protection: Interrupts the circuit when current climbs above its rating, helping shield the wiring and connected components from overheating and damage.
  • Resettable operation: Unlike a one-time fuse, a circuit breaker trips and can be reset, so the circuit can be restored once the fault condition is cleared.
  • Direct-fit replacement: Designed to replace the original circuit breaker on the listed applications.

A circuit breaker that will not stay set, keeps tripping, or leaves a circuit dead can be a sign the original unit has failed. If a faulty circuit breaker is the cause, this FH49 replaces it — but always diagnose the circuit first, since a persistent trip can also indicate a short or overload elsewhere.

Frequently Asked Questions

What does this circuit breaker do?

It protects an electrical circuit by interrupting the flow of current when it exceeds the breaker's rating, helping guard the wiring and connected components from overheating and damage.

Which vehicles does the FH49 fit?

It is a direct-fit replacement for the 2008-2014 Scion xD and the 2006-2014 Toyota Yaris. Check the Buyer's Guide tab to confirm the fit for your vehicle.

How is a circuit breaker different from a fuse?

A fuse blows once and must be replaced, while a circuit breaker trips and can be reset, restoring the circuit after the fault condition has been cleared.

What numbers does this part interchange with?

The FH49 interchanges with FH158, FH6307, and 8262052050. Its manufacturer part number is FH49.

My circuit breaker keeps tripping — will this fix it?

If a failed circuit breaker is the cause, this replaces it. Repeated tripping can also point to a short or overload in the circuit, so diagnose the circuit before replacing the part.
