The Wacker Neuson Relay is a genuine OEM component designed for the RC50, RC70, and RC110 series single drum soil compactors. Sourced directly from Wacker Neuson, this relay meets the exact electrical specifications required for correct operation across all covered models, including ROPS and CAB configurations. Genuine OEM designation means this part matches the original component precisely — no guesswork on fitment or compatibility. Whether you're servicing an RC50, an RC70VO, or an RC110p, part number is the correct replacement relay for your machine.
Key Features
- Correct Switching Specification — Genuine OEM construction ensures the relay operates at the precise voltage and current ratings required by the machine's electrical system, preventing erratic switching or circuit faults.
- Direct Plug-In Replacement — Engineered to match the original connector footprint and terminal configuration, allowing straightforward installation without modification to wiring harnesses or mounting brackets.
- Broad RC Series Coverage — Fits RC50, RC50p, RC70, RC70p, RC70VO, RC110, RC110p, and RC110 CAB and ROPS variants, making it a reliable stock item for fleets running multiple Wacker Neuson compactor models.
- Electrical Circuit Integrity — A functioning relay ensures clean, controlled power delivery to downstream systems; a failed relay can cause complete loss of function in the circuit it controls, sidelining the compactor mid-job.
- Electrical Safety Compliance — As a load-switching component in the machine's electrical system, using the correct OEM-rated relay helps prevent overloading, arcing, or unintended circuit behavior that could damage the wiring harness or connected components.
A relay is an electrically operated switch that allows a low-current control signal — from a switch, sensor, or controller — to open or close a higher-current circuit powering motors, solenoids, or other working components on the compactor. On Wacker Neuson RC series soil compactors, relays are used throughout the machine's control and power circuits to manage functions reliably and protect sensitive electronics from high load currents. When a relay fails, the circuit it controls will either stop responding entirely or behave intermittently, often appearing as an unexplained electrical fault that can be difficult to diagnose without first ruling out the relay itself.
