Detailed Description

Standard Ignition FH45 is a replacement circuit breaker used in vehicle electrical and body systems where controlled circuit protection is required. Its 4-blade terminal layout, female terminal gender, and rectangular connector design support a direct-fit style installation in applications that call for this configuration. This part cross-references Monroe Shocks & Struts (e.g., 2438089914, FB6303) for the same application. Compatible With 2017-2023 Nissan Armada, N/A; 2005-2021 Nissan Frontier, N/A; 2014-2020 INFINITI QX80, N/A; 2014-2015 Nissan Pathfinder, N/A, 4 Blade Term.; 2005-2015 Nissan Xterra, N/A; 2011-2013 INFINITI QX56, N/A; and 2005-2012 Nissan Pathfinder, N/A.

What It Helps Solve

  • Intermittent loss of power to protected electrical circuits
  • Repeated circuit interruptions caused by overload conditions
  • Faulty breaker replacement needs in body or lighting circuits
  • Connector mismatch when replacing an existing 4-terminal breaker
  • Electrical protection issues in select Nissan and INFINITI platforms

Installation Notes and Tips

Verify the connector shape, terminal count, and 12-volt specification before installation. Match the existing breaker layout and mounting bracket style to the original unit, and confirm the vehicle application by year, make, model, and terminal configuration. For 2014-2015 Nissan Pathfinder applications, confirm the 4 blade terminal note before ordering.
