2753050000

Overview

Weidmüller 2753050000 is a split-core current transformer designed for electrical measurement applications. It features a primary current rating of 250 A and a maximum secondary current of 5 A. The device supports a load capacity of 1 VA and maintains a tolerance class of 0.5, ensuring accurate signal transmission for monitoring and control systems.

Feature Summary

• Split-core design enables installation around existing conductors without disconnecting the primary circuit.
• Provides galvanic isolation between high-voltage primary circuits and low-voltage secondary measurement devices.
• Ensures precise current transformation with defined tolerance characteristics for reliable data acquisition.

Applications

• Electrical energy metering in industrial distribution panels
• Monitoring primary current loads in automation control systems
• Integration with protective relays requiring isolated current signals

Procurement Notes

Verify that the specified primary current of 250 A matches the conductor size and load requirements of the target installation. Confirm that the connected burden does not exceed the 1 VA limit to maintain the 0.5 tolerance class accuracy. Ensure the split-core mechanism accommodates the diameter of the cable being monitored during procurement planning.

Selection Notes

Select this component when non-intrusive installation on a fixed 250 A primary conductor is required. The 5 A secondary output must be compatible with the input specifications of the downstream measuring instrument or relay. Consider the physical aperture size of the split core to ensure it fits the specific cable insulation diameter present in the application environment.

Part Context

This component belongs to Weidmüller's range of current transformers, which are essential for isolating and scaling high currents for safe measurement. These devices support industrial infrastructure by providing accurate feedback for energy management and system protection without exposing control electronics to high voltage potentials.

Replacement Considerations

Ensure any substitute part matches the 250 A primary rating, 5 A secondary output, and 1 VA burden capacity. Verify that the replacement also offers a split-core configuration and meets the same 0.5 tolerance class to maintain system accuracy and compatibility with existing wiring.

FAQ

Can this transformer be installed on a busbar?

The split-core design allows installation around conductors; however, the physical aperture size must accommodate the specific dimensions of the busbar or cable being monitored.

What is the maximum burden this unit can handle?

The device is rated for a maximum load of 1 VA to ensure the specified 0.5 tolerance class accuracy is maintained.
