A6X30133574

Power Transformers Overview

The Siemens A6X30133574 is an industrial control power transformer (CPT) designed for electrical isolation and voltage conversion in automation systems. It features a rated capacity of 750 VA, stepping down primary voltages of 208 VAC or 277 VAC to a secondary output of 120 VAC. The unit incorporates a built-in primary fuse for overcurrent protection and includes a dedicated secondary winding for monitoring purposes. Constructed with standard industrial insulation materials, it supports continuous operation within typical ambient temperature ranges required for control cabinet environments.

Power Transformers Feature Summary

• Provides galvanic isolation between primary power circuits and secondary control loads
• Integrates primary-side fusing for circuit protection against short circuits
• Includes a separate auxiliary winding for external voltage monitoring applications

Power Transformers Applications

• Industrial control panel voltage transformation
• Machine tool power supply units
• Automation system control circuits requiring 120VAC isolation

Power Transformers Procurement Notes

Verify the specific primary voltage configuration (208V vs 277V) and mounting requirements against the official Siemens datasheet before procurement. Confirm that the 750 VA rating meets the total load demand of the connected control components. Ensure compatibility with existing enclosure space and thermal management provisions.

Power Transformers Selection Notes

Select this component when isolated 120 VAC power is required from higher voltage industrial sources. Consider the 750 VA capacity limit to ensure no overload occurs during peak operation. Evaluate the need for the integrated primary fuse versus external protection schemes based on system safety standards.

Power Transformers Part Context

This part belongs to Siemens' industrial control power transformer portfolio, specifically engineered for DIN rail or panel mounting in control cabinets. It serves as a critical interface for converting distribution voltages to safer control levels while maintaining electrical separation.

Power Transformers Replacement Considerations

Cross-reference with Siemens part number 3RT6916-1AA00 if verifying equivalent specifications within the same product family. Ensure any substitute matches the 750 VA rating and dual-winding configuration.
