The Wacker Neuson Relay DPDT 8 Pin 12VDC is a genuine OEM component designed for the HI 770 XHD Indirect Air Heater series, including Arctic Bear XHD and Arctic Bear XHD NS configurations. As a factory-sourced part, the delivers the exact electrical switching characteristics required by the original heater control circuit — no guesswork on compatibility. This relay fits across multiple HI770XHD build variants, making it the correct choice whether you're servicing a dual-12 outlet, single-16 outlet, single-20 outlet, or Extra Heavy Duty Air Heater configuration.
Key Features
- Correct Switching Specs: — Double-pole double-throw (DPDT) design with an 8-pin configuration and 12VDC coil rating matches the original circuit requirements of the HI 770 XHD heater control system exactly.
- Genuine OEM Sourcing: — Manufactured to Wacker Neuson's own specifications, this is the same relay installed on the production line — not an approximation of it.
- Direct 8-Pin Drop-In: — The 8-pin base seats directly into the existing relay socket, making installation straightforward without rewiring or adapter hardware.
- Broad HI770XHD Coverage: — Fits Arctic Bear XHD, Arctic Bear XHD NS, and multiple HI770XHD build configurations including 2x12, 1x16, 1x20, and Extra Heavy Duty variants.
- Electrical Safety Compliance: — A correctly rated relay prevents overloading the heater's control circuit; an undersized or mismatched relay can cause erratic ignition behavior or uncontrolled heater cycling — a genuine concern on diesel-fired indirect heaters.
A DPDT relay is an electrically operated switch that controls two separate circuits simultaneously using a single 12VDC coil signal. In an indirect diesel air heater like the HI 770 XHD, the relay plays a central role in managing ignition sequencing, burner control, and safety shutdown functions — essentially acting as the command switch between the heater's control board and its operating components. When this relay fails, the heater may not ignite, may shut down unexpectedly, or may fail to respond to thermostat signals, leaving the jobsite without heat in demanding cold-weather conditions.
