Terminals
These relays handle the high starting (inrush) currents that often occur when turning on a vehicle. Also known as ISO relays, their blade terminals meet ISO 8092-1 dimensional standards to fit in road vehicles for easy maintenance and repair.
Relays for surface mounting have a tab for added security in high-vibration applications.
Relays with surge suppression coverage prevent damage to sensitive equipment by reducing the 300V to 500V spike that happens when you switch relays off. Relays with partial surge suppression coverage bring this spike down to 100V.

Weatherproof High-Starting-Current Vehicle Relays
Crimp-On
Terminals
An extended housing shields the terminals on these relays from weather. They're also rated IP54—when they're plugged into the relay socket, they're sealed to keep splashing water, like rain, from getting inside. They handle high starting (inrush) currents that often occur when turning on a vehicle. To prevent damage to sensitive equipment, these relays will partially suppress a momentary surge in voltage when the relay switches off. They’ll take a voltage spike of 300V to 500V and bring it down to 100V.
