Our ISO Mini Relays are compact, modular, general-purpose relays that allow you to tailor your vehicle's hard-wired box for the capability you need, including lighting, starting, horn, heating and cooling, or fan control.

Adhering to the ISO Mini 6.3 mm form factor, these relays plug into existing, ISO Mini boxes along with fuses or other components (sold separately).

This series offers a wide selection of Mini relays to meet the requirements of a variety of applications. Options include Form A (SPST), Form 2A (SPST with two terminals), and Form C (SPDT) relays, versions with resistor suppression, diode suppression, or no suppression, and models that are sealed (IP64), unbracketed or unsealed (IP40), bracketed configurations.

Features and Benefits

  • Broad offering of Form A (SPST), Form 2A (SPST with two terminals), and Form C (SPDT) relay options
  • Rated for either 18 V max with a 12 V dc coil rating or 36 V max with a 24 V dc coil rating
  • Versions are available with either a 20 A or 40 A continuous current rating
  • Suppression options include resistor, diode, and no suppression
  • Sealed (IP64) and unsealed (IP40) versions to match the water- and dust-protection requirements of your application
  • Bracketed options are available for panel mounting
