MTG0350I

Power Transformers Overview

The Siemens MTG0350I is a single-phase control power transformer with a 350VA rating. It features a primary voltage configuration of 380/400/415 V AC and offers secondary output options of 220 V or 110 V. The unit utilizes screw-type terminals for electrical connections and is designed for chassis mounting. This component provides isolated power conversion for industrial control circuits, ensuring safe operation within standard voltage ranges.

Power Transformers Feature Summary

• Provides finger-safe protection when used with compatible terminal cover kits
• Meets IP-20 specifications per IEC 529 standards
• Designed for chassis mounting applications

Power Transformers Applications

• Industrial control circuit power supply
• Machine tool control systems
• Electrical panel isolation

Power Transformers Procurement Notes

Verify the specific secondary voltage requirement (110V or 220V) against the application schematic before ordering, as the model designation may imply a standard configuration but field variations exist. Confirm that the installation environment allows for chassis mounting and that appropriate IP-20 terminal covers are procured separately if personnel safety requirements mandate finger-safe protection during maintenance.

Power Transformers Selection Notes

Select this transformer when a 350VA capacity is required to step down standard European or international primary voltages (380-415V) to lower control voltages. Ensure the load does not exceed the rated VA to prevent overheating. Verify that the physical dimensions accommodate the available chassis space and that the screw-terminal interface matches existing wiring practices.

Power Transformers Part Context

This component belongs to the Siemens MTG series of industrial control power transformers. The series is characterized by robust construction and compliance with international safety standards. The MTG0350I specifically addresses the need for reliable power isolation in environments where standard mains voltage must be reduced for sensitive control logic or signaling devices.
