Keep power flowing to a protected accessory circuit with the Standard Ignition Circuit Breaker FH43. It's a direct-fit replacement for the listed applications: the 2013 INFINITI JX35, 2014-2020 INFINITI QX60, 2013-2018 NISSAN ALTIMA, 2016-2023 NISSAN MAXIMA, 2015-2023 NISSAN MURANO, and 2013-2020 NISSAN PATHFINDER.
Overcurrent protection: opens the circuit when current rises above its limit, helping guard the wiring and the connected accessory from damage.
Circuit breaker function: unlike a single-use fuse, a circuit breaker interrupts the circuit during a fault rather than burning out.
Direct-fit replacement: installs in place of the original circuit breaker on the listed applications above.
A circuit breaker sits inline to monitor current and break the connection when it detects an overload or short, then holds the circuit open until the condition is addressed. If the accessory on this circuit keeps losing power intermittently, or a breaker that repeatedly trips is the cause, replacing it with the FH43 restores a sound protective device. Diagnose the underlying fault before assuming the breaker is at fault, since a persistent overload can trip a healthy breaker.

Frequently Asked Questions
What does this circuit breaker do?
It sits inline in an electrical circuit and interrupts current flow when it detects an overload or short, helping protect the wiring and the connected accessory from damage.
Will the FH43 fit my vehicle?
It's a direct-fit replacement for the 2013 INFINITI JX35, 2014-2020 INFINITI QX60, 2013-2018 NISSAN ALTIMA, 2016-2023 NISSAN MAXIMA, 2015-2023 NISSAN MURANO, and 2013-2020 NISSAN PATHFINDER.
How is a circuit breaker different from a fuse?
A fuse burns out once and must be replaced after a fault, while a circuit breaker interrupts the circuit during a fault instead of destroying itself.
What numbers does this part interchange with?
It cross-references FH152, FB6301, and 243803JA1A. Its own manufacturer part number is FH43.
What are signs this circuit breaker may need replacing?
An accessory on the circuit that intermittently loses power, or a breaker that trips repeatedly, may indicate a failed breaker. Diagnose the circuit first, since an overload can trip a good breaker.
