2277792

Overview

Phoenix Contact part number 2277792 is a PACT series bus-bar current transformer designed for industrial applications. It features a primary current rating of 500 A and a secondary output of 5 A. The device supports a supply voltage of 1000 V and has a burden rating of 10 VA. It includes a 21 mm bore diameter for conductor passage and utilizes terminal block termination. The unit is certified to UL standards.

Feature Summary

• Bus-bar design for direct conductor mounting
• Terminal block termination style
• PACT series classification

Applications

• Industrial current monitoring
• Electrical protection systems
• Power distribution measurement

Procurement Notes

Verify the specific datasheet version for the exact accuracy class and frequency range, as these parameters define performance limits. Confirm that the 21 mm bore accommodates the target conductor size without interference. Ensure the installation environment meets the thermal and voltage ratings specified in the official Phoenix Contact documentation before finalizing the order.

Selection Notes

Select this component when a 500 A primary rating and 5 A secondary output are required for AC current sensing. The 10 VA burden capacity must match the connected load impedance. Consider the 21 mm bore dimension relative to the cable thickness. Verify that the terminal block interface aligns with the control panel wiring scheme and that the DIN rail or mounting method suits the enclosure layout.
