A6X30155479

Power Transformers Overview

The Siemens A6X30155479 is a Control Power Transformer (CPT) designed for industrial applications. It features a power rating of 500VA and supports primary voltages of 240V and 480V, with a secondary output voltage of 120V. The unit utilizes an AID insulation class for thermal management and is configured for chassis mounting. This component serves as a step-down transformer to provide isolated control circuit power from standard industrial line voltages.

Power Transformers Feature Summary

• Provides isolated 120V secondary power from 240V or 480V primary sources
• Rated at 500VA capacity for industrial control circuits
• Constructed with AID insulation class for enhanced thermal performance
• Designed for secure chassis mounting in electrical enclosures

Power Transformers Applications

• Industrial control panel power distribution
• Machine tool control circuit isolation
• Automated manufacturing system power supply
• HVAC control system voltage transformation

Power Transformers Procurement Notes

Verify the specific primary voltage configuration required for your installation, as the unit supports both 240V and 480V inputs. Confirm that the chassis mounting dimensions align with your enclosure design. Ensure the 500VA rating meets the total load requirements of your downstream control components. Check for any regional compliance certifications necessary for your specific market application before finalizing the order.

Power Transformers Selection Notes

Select this transformer when a reliable step-down solution from high-voltage industrial lines to 120V control levels is needed. The 500VA rating suits moderate-load applications. Consider the AID insulation class if operating in environments with higher ambient temperatures. Chassis mounting is ideal for fixed installations within dedicated electrical cabinets rather than portable setups.

Power Transformers Part Context

This component belongs to Siemens' industrial control transformer lineup, specifically engineered for robustness in demanding factory environments. It replaces older models requiring similar voltage transformations. The part number indicates a specific configuration within the broader CPT family, distinguished by its 500VA capacity and dual-primary voltage capability.

Power Transformers Replacement Considerations

Direct substitutes must match the 500VA rating, 240/480-120V transformation ratio, and chassis mounting style. Verify physical footprint compatibility if space is constrained. Ensure the replacement also meets AID insulation standards for equivalent thermal reliability in continuous operation scenarios.
