Wacker Neuson 5000156890 Electrical Equipment Relay

The Wacker Neuson is a genuine OEM Electrical Equipment Relay designed for the RD25 and RD15 hydrostatic double drum vibratory tandem rollers. As a factory-sourced component, this relay matches the original electrical specification of the machine, ensuring proper circuit switching behavior without adaptation or guesswork. It is a direct OEM replacement confirmed for both the RD25 and RD15 roller series.

Key Features

• OEM-Matched Switching Spec — Sourced directly from Wacker Neuson, this relay meets the exact coil voltage and contact rating of the original, ensuring circuits switch correctly under load.
• Drop-In Connector Fit — Designed to plug into the existing relay socket on RD25 and RD15 machines, matching the OEM footprint and terminal layout for a straightforward swap.
• Confirmed Fitment for RD-Series Tandem Rollers — Verified for the RD25 and RD15 hydrostatic double drum vibratory rollers, so you can order with confidence.
• Protects Downstream Electrical Systems — A functioning relay correctly isolates and switches electrical circuits; a failed relay can cause system faults, unexpected shutdowns, or damage to connected components.
• Genuine OEM Traceability — Carrying the Wacker Neuson part number 5000156890, this component is traceable back to the original design, supporting accurate service records and repeat ordering.

An electrical equipment relay is a switching device that uses a low-power control signal to open or close a higher-current circuit within the machine's electrical system. On tandem rollers like the RD25 and RD15, relays manage power flow to key operating systems — protecting circuits and ensuring that functions activate and deactivate as commanded. When a relay fails, the circuit it controls may stop responding entirely or behave erratically, leading to operational faults that can ground the machine until the component is replaced.
