The Kleinn Model 340 is a premium, universal standard automotive electrical relay engineered to provide safe, reliable, and high-capacity power switching within your high-pressure onboard air system. Featuring a heavy-duty, Single Pole Double Throw (SPDT) 5-prong configuration enclosed in a protective black ABS plastic housing, this relay is designed to withstand the demanding conditions of automotive engine bays and chassis environments. Rated for a robust 30 Amps of continuous current and up to 40 Amps momentarily, it acts as a crucial safety barrier—allowing a low-amperage dash switch to cleanly trigger high-draw pneumatic components, such as your air compressor or high-performance solenoid valves, while completely safeguarding your vehicle's delicate factory wiring.
