This is a Terex Relay, part number 51574340. A relay is an electrical part that lets a small control signal switch another circuit on or off, so the switch or controller doesn't have to carry the full load of the device it operates. Order by the exact part number, because electrical parts that look alike can differ in ways you can't see from the outside, and the number is the only reliable way to match the right one.

A relay uses a small control signal to switch a separate circuit. On equipment, this keeps heavy current away from dash switches and controllers while still letting them operate lights, starters, pumps or other electrical loads.
Common signs include a circuit that works intermittently or not at all, a relay that clicks but the load doesn't respond, a load that stays on when it should shut off, and burnt, melted or corroded terminals or housing. Because other faults can look the same, check wiring, connectors and the circuit's other components as the machine's service manual describes before replacing the relay.
Have the part number (51574340), the machine model and serial number, and the quantity you need. A photo of the old relay and its location on the machine can also help the parts team confirm the match.
No. The store SKU (7109147) is an internal reference for this listing. Order and cross-check by the part number, 51574340.
