How to Choose the Right Fuse

  • Match amperage: Replace like for like at 20A unless the manufacturer specifies otherwise.
  • Voltage rating: Fuse rating must meet or exceed system voltage. This part is suitable up to 32V DC.
  • Form factor: Micro blade only. Mini or standard blade sizes will not fit micro slots.
  • Environment: For under bonnet or exposed installs, use sealed in-line micro holders.
  • Repeated blows: Diagnose wiring or component faults rather than upsizing the fuse.
