The Wacker Neuson is a genuine OEM 380/400/415V 50Hz Current Transformer designed for the PSA2-1503L and PSA2-2203L portable generator series. As a direct Wacker Neuson factory part, the is manufactured to the exact electrical specifications required for correct output monitoring and protection on these machines. It fits the PSA2-1503L and PSA2-2203L generators with no modification, slotting directly into the original mounting position. Keeping this component in good working order is essential to maintaining accurate current measurement and safe generator operation on the jobsite.
Key Features
- Matched Electrical Specification — Rated for 380/400/415V at 50Hz, this transformer is wound and calibrated to the exact output parameters required by the PSA2 generator platform, ensuring accurate current sensing across all rated voltage configurations.
- Genuine OEM Part — Sourced directly from Wacker Neuson, part number 5000178378 meets the original design tolerances and insulation ratings specified for this generator model, not a generically rated substitute.
- Direct-Fit Replacement — Engineered as a drop-in replacement for the PSA2-1503L and PSA2-2203L, with the same mounting footprint and terminal configuration as the original component.
- Verified Fitment for PSA2 Series — Confirmed compatibility with the PSA2-1503L and PSA2-2203L generator models, giving you confidence when ordering for a specific machine.
- Electrical Safety Compliance — A correctly rated current transformer ensures the generator's protection and metering circuits operate within design limits; an incorrect or failed unit can cause inaccurate load readings or trigger unintended shutdowns under live load conditions.
A current transformer monitors the flow of electrical current through the generator's output circuits by producing a proportional, reduced-level signal that the control board or metering system can safely read. In a multi-voltage machine like the PSA2 series, it must be precisely matched to the rated voltage and frequency — in this case 380/400/415V at 50Hz — to deliver accurate readings. If the transformer degrades or fails, the generator may display incorrect load data, trip protection circuits unnecessarily, or fail to detect an overcurrent condition, all of which affect both machine reliability and operator safety.
