2277637

Overview

The Phoenix Contact 2277637 is a PACT MCR-V2-3015 window-type current transformer designed for measuring alternating currents. It features a primary current rating of 200 A AC and an AC secondary current rating of 5 A. The device operates within a frequency range of 50 Hz to 60 Hz and has an accuracy class of 1. Its rated power is 5 VA. The unit supports DIN rail and panel installation styles, with physical dimensions including a height of 82 mm and a length of 60 mm.

Feature Summary

• Window-type design for non-intrusive measurement of alternating currents
• High thermal stability with rated continuous current at 1.2 times the nominal value
• Robust surge protection capability up to 2.5 times the thermal rated short-time current

Applications

• Industrial process automation monitoring
• Electrical energy management systems
• Power distribution network analysis

Procurement Notes

Verify the specific ordering suffix matches the required configuration, as variations exist within the PACT series. Confirm that the 200 A primary rating aligns with the target circuit load. Ensure compatibility with standard DIN rail mounting infrastructure or panel cutouts specified in the mechanical drawings. Cross-reference the 5 VA burden capacity with connected instrumentation requirements to prevent saturation.

Selection Notes

Select this model when precise measurement of high-amperage AC lines is required without breaking the conductor. The 5 A secondary output is suitable for standard industrial ammeters and PLC analog inputs. Consider the 1% accuracy class for applications demanding reliable data fidelity. Evaluate the 5 VA power rating against the total burden of downstream devices to ensure signal integrity under full load conditions.

Part Context

This component belongs to the Phoenix Contact PACT MCR-V2 series of plug-in current transformers. These devices are engineered for integration into control cabinets and switchgear assemblies. The series provides standardized interfaces for connecting to various measurement and control modules, facilitating modular system expansion in industrial environments.

Replacement Considerations

Direct substitutes include other Phoenix Contact models within the PACT MCR-V2 family that share identical electrical ratings. Verify that any alternative part maintains the 200 A primary and 5 A secondary specifications. Ensure mechanical compatibility with existing DIN rail or panel mounting arrangements before substitution.
