2277695

Overview

The Phoenix Contact 2277695 is a window-type current transformer from the PACT MCR-V2 series. It features a primary current rating of 750 A AC and a secondary current output of 5 A AC. The device operates within a frequency range of 50 Hz to 60 Hz and maintains an accuracy class of 1. With a rated power of 10 VA, it supports standard industrial measurement requirements. The unit is designed for DIN rail or panel mounting and includes a 33 mm bore size for conductor passage.

Feature Summary

• Window-type construction allows for easy installation around existing busbars or cables without circuit interruption.
• High accuracy class 1 ensures reliable current measurement for industrial monitoring applications.
• Versatile mounting options support both DIN rail and panel installation configurations.

Applications

• Industrial energy monitoring systems
• Electrical distribution panel metering
• Current sensing in automation control circuits

Procurement Notes

Verify the specific ordering code 2277695 against your bill of materials to ensure compatibility with existing 750 A primary and 5 A secondary system designs. Confirm that the 10 VA burden capacity meets the connected instrument requirements. Check availability status as stock levels may vary by region. Ensure the 33 mm bore dimension accommodates the target conductor size before finalizing procurement orders.

Selection Notes

Select this component when a 750 A primary current rating and 5 A secondary output are required for AC systems operating at 50-60 Hz. The accuracy class 1 specification makes it suitable for precise measurement tasks rather than simple protection. Consider the 10 VA rated power to ensure the connected load does not exceed the transformer's capacity. Verify that the physical dimensions fit the available DIN rail or panel space in the enclosure design.

Part Context

This part belongs to the Phoenix Contact PACT MCR-V2 series of current transformers. The series offers various primary current ratings and bore sizes to suit different industrial applications. The 2277695 model specifically addresses high-current measurement needs with a 750 A rating. It complements other models in the lineup that provide lower current ranges or different secondary outputs for diverse system architectures.

Replacement Considerations

Direct substitutes must match the 750 A primary, 5 A secondary, and 10 VA specifications. Verify bore diameter compatibility if replacing in existing installations. Cross-reference accuracy class requirements to ensure measurement precision remains consistent. Consult manufacturer documentation for approved alternative part numbers within the same product family.
