2277954

Overview

Phoenix Contact part number 2277954 is a PACT MCR-V2-6015 window-type current transformer designed for DIN rail mounting. It features an 85mm aperture and supports a primary current of 1000 A AC with a secondary output of 5 A AC. The device operates within a frequency range of 50 Hz to 60 Hz and has a power rating of 15 VA. It achieves accuracy class 1, ensuring high precision for electrical measurement applications.

Feature Summary

• Window-type design with 85mm aperture for easy installation around conductors
• High precision accuracy class 1 for reliable current sensing
• DIN rail adapter compatibility for secure mounting in control cabinets

Applications

• Industrial energy monitoring systems requiring precise current data
• Electrical distribution panels for load management
• Automation equipment integrating current feedback loops

Procurement Notes

Verify the specific model suffix matches the required aperture and current rating. Confirm that the operating environment meets indoor usage requirements and altitude limits. Ensure the primary conductor fits within the 85mm window clearance. Check for compliance with local safety standards such as UL or EN 61869 before finalizing procurement.

Selection Notes

Select this component when a 1000 A primary current and 5 A secondary output are required. The 15 VA burden capacity must align with connected metering devices. Consider the 85mm aperture size relative to available busbar dimensions. Accuracy class 1 is suitable for billing-grade or critical monitoring tasks where standard industrial sensors may lack sufficient precision.
