The Wacker Neuson Relay is a genuine OEM component designed for HI750 and HI900 series indirect-fired air heaters and E3000 series generators. As a direct factory replacement, this relay meets the original electrical specifications required for safe, consistent operation across the full range of compatible models — including diesel, gas, and diesel-generator variants. Wacker Neuson genuine OEM parts are manufactured to the same standards as the components installed at the factory, so you can fit the with confidence. Fitment spans multiple HI750 and HI900 configurations — skid-mounted, mobile, surge-brake, and extreme cold (-40°) variants — as well as the CUB700GM and multiple E3000 configurations.
Key Features
- Correct Switching Specification: — Matched to the original coil voltage and contact rating for HI-series heater and E3000 generator control circuits, ensuring the relay switches loads as designed.
- Genuine OEM Part: — Sourced directly from Wacker Neuson, this relay carries the same part number and build spec as the original — no guesswork on compatibility.
- Broad Series Fitment: — Covers HI750 (gas, diesel, DGM, and HD variants), HI900 (gas, diesel, DGM, and surge-brake variants), CUB700GM, and multiple E3000 generator configurations.
- Uninterrupted Heater and Generator Control: — A functioning relay is essential for proper start sequencing and load switching; a failed relay can prevent ignition or cause erratic operation in demanding cold-weather applications.
- Cold-Weather Application Rated: — Specified for units used in extreme-cold (-40°) deployments, making this relay suitable for the harshest construction-site heating scenarios.
A relay is an electrically operated switch that allows a low-current control signal to open or close a higher-current circuit. In indirect-fired air heaters and portable generators, relays manage critical functions such as fuel system activation, ignition sequencing, and load control — tasks where precise, repeatable switching is essential. When a relay fails, it can cause the machine to refuse to start, cycle erratically, or lose control of key systems; replacing it promptly with the correct part restores normal operation and protects downstream electrical components from damage caused by improper switching behavior.
