2905885

Overview

Phoenix Contact part number 2905885 is a window-type current sense transformer belonging to the PACT MCR-V2 series. It features a primary round conductor bore diameter of 52 mm and supports an AC primary current rating of 800 A with a secondary output of 1 A. The device operates at frequencies between 50 Hz and 60 Hz, delivering a burden capacity of 2.5 VA. Designed for DIN rail mounting, this plug-on converter facilitates precise current monitoring in industrial electrical systems.

Feature Summary

• Window-type construction allows direct installation around existing busbars or cables without circuit interruption
• Provides galvanic isolation between high-current primary circuits and low-voltage secondary measurement inputs
• Engineered for reliable signal transmission within standard industrial frequency ranges

Applications

• Integration into energy metering systems for accurate power consumption tracking
• Connection to programmable logic controllers for real-time current monitoring
• Implementation in industrial automation panels requiring phase current feedback

Procurement Notes

Verify that the required primary conductor diameter does not exceed the specified 52 mm window size. Confirm compatibility with downstream devices accepting 1 A secondary outputs. Ensure the operating environment remains within standard industrial temperature limits. Check for specific certification requirements such as RoHS compliance if mandated by local regulations. Validate mechanical mounting constraints against available DIN rail space.

Selection Notes

Select this component when a non-invasive current sensing solution is required for conductors up to 52 mm in diameter. Choose this model for applications demanding a 1 A secondary output compatible with standard industrial instrumentation. Consider this unit for installations where DIN rail mounting simplifies assembly and maintenance. Evaluate the 2.5 VA burden capacity to ensure it meets the impedance requirements of connected measuring devices.
