MT0250J is listed in the Power Transformers range at ChipApex. The manufacturer field lists Siemens. Its product description is PWR XFMR 250VA CHAS MT. Review the specifications below when checking this part for your BOM.
The Siemens MT0250J is a 250VA control power transformer designed for chassis mounting. It features terminal block termination and measures 139.95mm in length by 114.30mm in width, with a maximum installation height of 113.54mm. The primary voltage ratings include 200V, 208V, 220V, 230V, 240V, 440V, 460V, and 480V. Secondary full-load voltages are available at 120V, 115V, 110V, 25V, 24V, and 23V. The component does not utilize a center tap.
Verify the specific primary and secondary voltage requirements against the official datasheet before procurement. Confirm that the chassis mounting dimensions align with the enclosure specifications. Ensure the terminal block termination style matches the existing wiring infrastructure. Check RoHS compliance status if environmental regulations apply to the project scope.
Select this model when a 250VA capacity is required for stepping down various high voltages to standard control levels. Consider the physical footprint constraints due to the chassis mount design. Evaluate the need for multiple secondary voltage options within a single unit. Verify compatibility with the operating frequency and ambient temperature conditions specified in the technical documentation.
This component belongs to the Siemens control power transformer series, originally associated with Furnas Electric Co. products acquired by Siemens. It serves as a critical interface for isolating and transforming line voltage to safer control circuit levels. The part number MT0250J identifies the specific electrical and mechanical configuration within the broader product family.
Public confirmed substitute part numbers are not available in the provided documentation. Cross-reference with Siemens or Furnas Electric catalogs for direct equivalents. Ensure any replacement maintains identical voltage ratings and physical mounting dimensions.
