The AVR H-84-12D is a high-quality 12V automotive relay featuring a built-in diode for surge suppression. This 5-pin relay is designed for reliable performance in various vehicle and machinery electrical applications, offering a 20A current rating for the normally closed (NC) contact and a 30A rating for the normally open (NO) contact. Its robust construction ensures durability and consistent operation in demanding environments. The integrated diode protects sensitive electronic components from voltage spikes generated when the relay coil de-energizes, making it a crucial component for safeguarding electrical systems.
