A6X30155477

Power Transformers Overview

The Siemens A6X30155477 is a control power transformer (CPT) with a rated capacity of 250VA. It supports primary voltages of 240V or 480V and provides a secondary output voltage of 120V at full load. The unit utilizes terminal block connections for secure electrical interfacing. Designed for industrial environments, it complies with RoHS standards and is classified under the AID series. This component facilitates reliable voltage conversion for control circuits in automation systems.

Power Transformers Feature Summary

• Provides isolated voltage transformation from standard industrial primary voltages to a controlled 120V secondary output
• Features robust terminal block connection style for secure wiring integration
• Complies with RoHS environmental directives for restricted hazardous substances

Power Transformers Applications

• Industrial control panel voltage step-down
• Automation system auxiliary power supply
• Machine tool control circuit isolation

Power Transformers Procurement Notes

Verify the specific part number A6X30155477 against official Siemens documentation to ensure compatibility with existing 240/480V primary systems. Confirm that the 250VA rating meets the thermal and electrical load requirements of the target application. Check for any recent product lifecycle updates or alternative recommendations from the manufacturer before finalizing procurement orders.

Power Transformers Selection Notes

Select this transformer when a dedicated 120V control voltage is required from 240V or 480V mains sources. Ensure the enclosure allows for adequate ventilation given the 250VA power dissipation. Verify that the terminal block configuration matches the available wiring space and connector types within the control cabinet design constraints.

Power Transformers Part Context

This component belongs to Siemens' industrial control power transformer lineup, specifically designed for DIN rail or panel mounting in electrical enclosures. It serves as a critical interface between high-voltage distribution networks and low-voltage control logic, ensuring signal integrity and operator safety through galvanic isolation.

Power Transformers Replacement Considerations

Consult Siemens technical catalogs for direct cross-reference numbers if A6X30155477 is discontinued. Verify that any substitute maintains identical 250VA capacity, 240/480-120V ratio, and terminal block form factor to ensure mechanical and electrical interchangeability.
