MT0050B

Power Transformers Overview

The Siemens MT0050B is a Class MT control power transformer designed for industrial applications. It features a primary voltage rating of 240x480 VAC and provides a secondary output of 24 VAC. The unit has a power capacity of 50 VA and operates at 50/60 Hz frequencies. This single-phase transformer utilizes epoxy encapsulation to seal coils against environmental contaminants, ensuring durability in hostile conditions.

Power Transformers Feature Summary

• Epoxy encapsulation seals coils against moisture, dust, dirt, and industrial contaminants
• Integrally molded barriers between terminals protect against electrical creepage
• Increased terminal contact area permits low loss operation

Power Transformers Applications

• Industrial control circuits
• Domestic applications requiring step-down power conversion
• Harsh environment machinery protection

Power Transformers Procurement Notes

Verify the specific ordering suffix and physical dimensions against the official Siemens datasheet before procurement. Confirm that the required accessories, such as fuse clips or jumpers, are included or purchased separately. Ensure the installation environment matches the epoxy encapsulation specifications for optimal performance and safety compliance.

Power Transformers Selection Notes

Select this model when a 50 VA capacity is sufficient for controlling lower-power industrial loads. The dual primary voltage options (240V or 480V) provide flexibility for different supply networks. The 24V secondary output is suitable for standard control relays and contactors. Verify space constraints due to the molded design.

Power Transformers Part Context

This component belongs to the Siemens Class MT series of control transformers. These units are engineered for reliability in demanding industrial settings. The MT designation indicates specific construction standards regarding insulation and thermal management. This series is widely used in automation panels where compact size and high protection ratings are required.

Power Transformers Replacement Considerations

Consult official Siemens documentation for direct cross-reference part numbers. Ensure any substitute maintains the 50 VA rating and 240x480V to 24V transformation ratio. Verify compatibility with existing mounting hardware and terminal configurations.
