The Wacker Neuson Relay is a genuine OEM electrical relay designed for a broad range of Wacker Neuson equipment, including RD-series tandem rollers, G-series mobile generators, CRT ride-on concrete trowels, LTW light towers, and CB14B tandem rollers. As a direct OEM replacement, is sourced and validated by Wacker Neuson to meet the original electrical specifications of the equipment it serves. This relay fits an extensive list of machine configurations across the RD12, RD16, RD27, G25, G70, G100, G120, G130, G150, G160, G180, G320, CRT48, LTW6K, LTW8K, and CB14B families. Ordering by part number confirms you are receiving the correct component for your specific machine.
Key Features
- Correct Electrical Switching Spec — Manufactured to the original contact rating and coil voltage required by Wacker Neuson circuits, ensuring the relay energizes and switches loads exactly as the system expects.
- Drop-In Terminal Fit — Matches the OEM connector footprint and terminal layout, so installation is straightforward with no rewiring or adapter harnesses.
- Broad Multi-Family Compatibility — A single part number covering RD tandem rollers, G-series generators, CRT ride-on trowels, LTW light towers, and CB14B rollers — confirm your machine number before ordering.
- Protects Downstream Electrical Components — A properly functioning relay isolates high-current circuits from control-side wiring; a failed relay can prevent starting, disable outputs, or cause unintended circuit activation.
- Genuine OEM Sourcing — Supplied directly through the Wacker Neuson parts network, carrying the same part validation as relays installed on the production line.
A relay is an electrically operated switch that allows a low-current control signal — such as a switch input or ECU output — to open or close a higher-current circuit safely. In equipment like generators, rollers, and trowels, relays manage critical functions including starter circuits, fuel system activation, lighting, and auxiliary outputs. When a relay fails, the circuit it controls stops functioning entirely or behaves erratically, which can prevent the machine from starting, shut down key systems mid-operation, or produce intermittent faults that are difficult to diagnose without replacing the component directly.
