Relay

Reliable control of engine systems A relay is an essential switch in the electrical system of trucks and agricultural machinery. It allows high-current circuits, such as the fuel filter heater, to be controlled safely. A properly functioning relay for the fuel filter heater prevents diesel from crystallising in frosty conditions. This is important for transport that operates throughout the winter and for agricultural machines that also need to start at low temperatures. For cold starts and monitoring In addition to fuel heating, Protempo also supplies the pre-heating relay, which controls the glow plugs for a smooth cold start. The coolant level relay is also an important component that protects the engine against overheating. The relays from febi are OE-compliant, which means they have the correct electrical specifications and fit seamlessly into the existing fuse box or wiring.
