Description
Our ISO Mini Relays are compact, modular, general-
purpose relays that allow you to tailor your vehicle’s power
Applications
• Lighting Control
• Starting Control
• Horn Control
distribution 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).
• Heating and Cooling Control
• Fan Control
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.
