2277103

Overview

Phoenix Contact part number 2277103 is a window-type current transformer from the PACT MCR-V2-3015 series. It features a primary current rating of 600 A AC and a secondary output of 5 A AC. The device has an accuracy class of 1 and a rated power of 10 VA. Thermal specifications include a continuous current of 1.2 times the nominal current (Id = 1.2 * In) and a short-time thermal current of 60 times the nominal current (Ith = 60 * In). The rated surge current is defined as 2.5 times the thermal rated short-time current (Idyn = 2.5 * Ith).

Feature Summary

• Window-type design for busbar or cable passage.
• Provides isolated 5 A AC secondary signal from high primary currents.
• High thermal overload capacity with specified short-time and continuous current ratings.

Applications

• Industrial energy monitoring systems.
• Electrical distribution panel metering.
• Protection relay input circuits.

Procurement Notes

Verify that the physical dimensions of the target conductor or busbar fit within the transformer's window aperture before ordering. Confirm that the connected measuring instrument accepts a 5 A AC input signal to ensure compatibility with the secondary output specification.

Selection Notes

Select this component when a 600 A primary current range is required with Class 1 accuracy. Ensure the installation environment supports the thermal ratings, specifically the Id and Ith limits. Verify that the downstream equipment matches the 5 A secondary output standard.

Part Context

This unit belongs to the PACT MCR-V2-3015 series of current transformers manufactured by Phoenix Contact. These devices are designed for DIN rail mounting integration in control cabinets. The series provides standardized interfaces for converting high primary currents into measurable secondary signals for industrial automation and monitoring applications.
