Description
Product Overview
The VIAIR 12V Relay (model 93980) is engineered for high‑current automotive applications. Featuring silver‑nickel contacts, it provides excellent conductivity and corrosion resistance, supporting a continuous current rating of 80 amps at 12 volts. The quick‑connect terminals simplify wiring, while the chassis‑mount style ensures a secure fit in vehicle control panels. Compact dimensions of 6 × 6 × 5.5 inches and a lightweight of 0.32 oz make it easy to integrate without adding bulk.
Usage
Designed for trucks, RVs, marine rigs, and off‑road vehicles, this relay excels in power‑distribution tasks such as fuel pump control, lighting circuits, and auxiliary equipment activation. Its normally open contact type guarantees that the circuit remains off until the relay is energized, providing safety and energy efficiency. Installers appreciate the 12‑volt coil voltage, which matches standard vehicle electrical systems, allowing seamless integration into existing harnesses.

FAQ
What is the difference between normally open and normally closed contacts?
A normally open (NO) relay keeps the circuit open until the coil is energized, which is ideal for safety‑critical applications where power should only flow when commanded.
Can this relay be used in marine environments?
Yes. The silver‑nickel contacts resist corrosion, and the sealed housing protects against moisture, making it suitable for marine and off‑road use.
Is the relay compatible with 24‑volt systems?
This specific model is designed for 12‑volt coils. For 24‑volt applications, select a relay with a matching coil voltage rating.
How do I replace a faulty relay in my vehicle?
Disconnect the battery, remove the mounting screws, unplug the quick‑connect terminals, and install the new VIAIR relay by reversing the steps. Ensure the coil voltage matches your system before powering up.
What warranty does VIAIR provide?
VIAIR offers a limited one‑year warranty covering manufacturing defects, giving you confidence in the relay’s quality and durability.
