Wacker Neuson 5100046062 Relay, Cube, 70A

The Wacker Neuson Relay, Cube, 70A is a genuine OEM component designed for the RD 24-100 and RD 27-120 series double drum rollers, including standard, cab, offset, and DPF-equipped variants. As a direct factory replacement, this relay carries the exact electrical rating and connector configuration required by these machines — no guesswork on compatibility. It fits a broad range of RD series models including the RD 24-100, RD 27-120, RD 28-120, and all corresponding DPF, cab, and offset configurations. Sourcing genuine Wacker Neuson ensures the part meets the precise switching specifications the machine's electrical system depends on.

Key Features

• Correct 70A Switching Capacity — Matched to the exact amperage rating required by the RD series electrical circuit, ensuring the relay handles load without risk of under-spec switching failures.
• Genuine OEM Part — Manufactured to Wacker Neuson's original design tolerances, with the proper coil voltage and contact resistance to integrate cleanly into the existing wiring harness.
• Broad RD Series Compatibility — Fits RD 24-100, RD 27-120, RD 28-120, and all cab, offset, and DPF variants, covering a wide range of production configurations under a single part number.
• Protects Downstream Electrical Components — A correctly rated relay prevents voltage irregularities from reaching sensitive circuits; a failed or undersized relay can cause erratic machine behavior or component damage.
• Electrical Safety Compliance — Using the OEM-specified relay maintains the integrity of the machine's electrical protection scheme, which is critical on equipment where relay failure can affect control system response.

A cube relay is a high-current switching device that controls power flow to major electrical circuits — such as starter motors, hydraulic solenoids, or auxiliary systems — by using a low-current signal to open or close a high-current contact. On Wacker Neuson RD series rollers, this 70A relay sits within the machine's control circuit and manages the load switching that keeps key systems operating on command. When a relay fails, symptoms typically include circuits that won't activate, intermittent electrical response, or complete loss of function in the system it controls — making prompt replacement essential to restore normal machine operation.
