2277967

Overview

The Phoenix Contact PACT MCR-V2-6015-85-1250-5A-1 (Part No. 2277967) is a window-type current transformer designed for high-accuracy electrical measurement. It features a primary rated current of 1250 A AC and a secondary output of 5 A AC, with an accuracy class of 1. The device has a rated power of 15 VA and operates at frequencies of 50 Hz or 60 Hz. Key thermal specifications include a short-time current rating of Ith = 60 * In and a continuous current rating of Id = 1.2 * In. The unit utilizes screw connections for flexible wires up to 10 mm² and supports mounting on DIN rails or panels.

Feature Summary

• Window-type design allows for non-intrusive installation around conductors
• High precision measurement capability with accuracy class 1
• Robust thermal performance handling surge currents up to 2.5 times the short-time rating

Applications

• Industrial energy monitoring systems
• Electrical panel metering and protection circuits
• Power distribution network analysis

Procurement Notes

Verify that the specific part number 2277967 matches the required primary current of 1250 A and secondary output of 5 A for your application. Confirm compatibility with the intended conductor diameter, which must not exceed 52 mm. Ensure the mounting environment supports the specified DIN rail or panel installation methods. Check that the system frequency aligns with the 50 Hz or 60 Hz operational range to maintain accuracy class 1 performance.

Selection Notes

Select this component when precise measurement of high alternating currents is required in industrial settings. The 1250 A primary rating suits heavy-duty applications, while the 5 A secondary output ensures compatibility with standard industrial meters. Consider the 15 VA burden capacity to ensure connected instruments do not exceed the transformer's rated power. The window type offers flexibility for retrofitting existing busbars or cables without breaking the circuit.
