The Wacker Neuson Current Transformer is a genuine OEM component designed for the HDR 45, HD 50, HD 70, HI35, HI 90, and HI 120HD indirect-fired air heater series. As a direct OEM replacement, this transformer is manufactured to the exact electrical specifications required by these heaters, ensuring correct sensing output and reliable control-circuit operation. It is a verified fit across the HDR 45, HD 50, HD 70, HI35, HI 90, and HI 120HD models, making it a straightforward drop-in service part when the original unit fails or becomes damaged.
Key Features
- OEM-Spec Electrical Output — Wound and rated to the precise current-sensing specifications required by Wacker Neuson indirect-fired heater control circuits, ensuring accurate signal delivery to the control board.
- Direct-Swap Installation — Matches the original mounting configuration and connector interface, allowing the transformer to seat and connect exactly as the factory unit does.
- Broad Heater Compatibility — Fits the HDR 45, HD 50, HD 70, HI35, HI 90, and HI 120HD indirect-fired air heater models, covering a wide range of Wacker Neuson heating equipment with a single part number.
- Sustained Heating Performance — A correctly functioning current transformer keeps the heater's control system reading load conditions accurately, supporting consistent burner operation and stable heat output in demanding cold-weather applications.
- Electrical Safety Compliance — Using the correct OEM-specified transformer maintains proper isolation between the high-current circuit and the low-voltage control circuit, which is critical for safe heater operation on the job site.
A current transformer monitors the electrical current flowing through the heater's main circuit and sends a scaled-down signal to the control board, allowing it to regulate burner operation and respond to fault conditions. Without an accurate reading from this component, the control system cannot properly manage the heating cycle, which can lead to erratic burner behavior, nuisance shutdowns, or failure to ignite. When the transformer degrades or fails, replacing it with the correct OEM part restores accurate current sensing and gets the heater running as intended.
