MT0050J

Power Transformers Overview

The Siemens MT0050J is a Class-MT industrial control transformer with a 50 VA power rating. It operates at 60 Hz and features primary voltage options of 200, 220, or 480 VAC. Secondary outputs include 110 VAC, as well as combinations of 23 x 110 VAC and 25 x 120 VAC. The unit utilizes screw-type terminals for connection and is designed for wall mounting. Operating temperatures range from -20°C to +40°C.

Power Transformers Feature Summary

• Completely epoxy encapsulated coils provide sealing against moisture, dust, dirt, and industrial contaminants.
• Designed for maximum protection in hostile environments.
• Includes secondary fuse clip and jumpers for configuration.

Power Transformers Applications

• Industrial control circuits
• Domestic applications
• Control power distribution

Power Transformers Procurement Notes

Verify the specific primary and secondary voltage configurations required for your application, as the MT0050J series offers multiple variants. Confirm that the operating environment temperature falls within the specified -20°C to +40°C range. Ensure compatibility with 60 Hz systems. Check for included accessories such as fuse clips and jumpers if immediate installation is planned.

Power Transformers Selection Notes

Select this model when a robust, encapsulated control transformer is needed for industrial or domestic use. The Class-MT designation indicates specific safety and performance standards. Consider the available secondary voltage options (110V, 23x110V, 25x120V) to match control circuit requirements. Verify physical dimensions and mounting style suitability for the enclosure.

Power Transformers Part Context

The MT0050J belongs to the Siemens Class-MT series of industrial control transformers. This series is characterized by epoxy encapsulation for environmental protection. Similar models in the series include the MT0050M and MTG0050Y, which share the 50 VA rating but differ in voltage configurations and terminal types.

Power Transformers Replacement Considerations

Direct replacements may include other Siemens Class-MT transformers with matching 50 VA ratings and compatible voltage inputs/outputs. Verify physical dimensions and mounting hole patterns to ensure fit. Ensure the replacement unit supports the same 60 Hz frequency and operating temperature range.
