KT4050

Power Transformers Overview

The Siemens KT4050 is a Class KT control power transformer designed for industrial applications. It features a 45 VA power rating and operates at 50/60 Hz frequency on a single phase. The unit accepts a primary voltage of 240/480 VAC and provides a secondary output of 24 VAC. Electrical connections are facilitated via screw terminals, ensuring secure contact. The physical dimensions are approximately 3.46 inches in height, 3 inches in width, and 3.55 inches in depth.

Power Transformers Feature Summary

• Class KT construction for industrial control environments
• Single-phase operation with defined primary and secondary voltages
• Screw terminal connection type for input and output circuits

Power Transformers Applications

• Enclosed starter accessories
• Industrial control systems
• Control products integration

Power Transformers Procurement Notes

Verify that the required configuration matches the standard KT4050 specifications, specifically the 240/480 VAC primary to 24 VAC secondary ratio and the 45 VA rating. Confirm that screw terminal connections are suitable for the installation environment. Ensure the application requires Class KT insulation standards and single-phase power distribution compatible with 50/60 Hz frequencies before finalizing the order.

Power Transformers Selection Notes

Select this model when a compact control transformer is needed for enclosed starters or similar industrial control panels. The 45 VA capacity supports moderate control loads. Verify that the existing wiring infrastructure accommodates screw terminals rather than plug-in or spring-clamp types. Ensure the available space meets the dimensional requirements of 3.46 x 3 x 3.55 inches for proper enclosure fitment.

Power Transformers Part Context

This component belongs to the Siemens Class KT series of control power transformers. These units are engineered to step down line voltage to lower control voltages for safe operation of control circuits. The KT4050 specifically addresses the need for reliable voltage transformation in compact industrial enclosures where space is limited but robust electrical isolation is required.

Power Transformers Replacement Considerations

Direct replacement requires matching the 45 VA rating, 240/480VAC primary, and 24VAC secondary specifications. Ensure the substitute part also utilizes screw terminals and fits within the same dimensional envelope. Verify that the replacement maintains Class KT insulation ratings and single-phase compatibility.
