2276146

Overview

Phoenix Contact part number 2276146 is a window-type current transformer from the PACT MCR-V2 series. It features a primary round conductor diameter of 42 mm and supports a primary AC current of 300 A with 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 rating 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 through-bar current measurement.
• High-accuracy Class 1 performance for precise monitoring.
• Robust thermal ratings supporting high overload conditions.

Applications

• Industrial energy monitoring systems.
• Electrical distribution panel metering.
• Motor protection and control circuits.

Procurement Notes

Verify the specific model suffix matches the required bore size and current ratio before ordering. Confirm that the application environment aligns with the thermal limits specified in the datasheet. Ensure compatibility with downstream measuring instruments requiring a 5 A secondary input. Check for any specific mounting hardware requirements associated with the 42 mm aperture.

Selection Notes

Select this component when a 300 A primary current range and 42 mm conductor clearance are necessary. The Class 1 accuracy makes it suitable for billing-grade or critical process monitoring applications. Consider the 10 VA burden capacity to ensure connected meters do not exceed the rated load. Evaluate the physical space constraints regarding the window diameter and mounting profile.

Part Context

This unit belongs to the Phoenix Contact PACT MCR-V2 series, which provides modular current transformers for industrial automation. The series is designed for DIN rail or panel mounting integration within control cabinets. It complements other signal conditioning modules by providing isolated current feedback for PLCs or data acquisition systems.
