2277145

Overview

The Phoenix Contact 2277145 is a window-type current transformer from the PACT MCR-V2-4012 series. It features an 800 A AC primary current and a 5 A AC secondary current, providing an 800:5 ratio. The device has a Class 1 accuracy rating and a 10 VA power rating. It operates within a frequency range of 50 Hz to 60 Hz. The unit supports DIN rail and panel mounting styles.

Feature Summary

• Window-type construction for non-intrusive current measurement
• Pluggable design for simplified installation
• Class 1 accuracy for reliable signal conversion

Applications

• Industrial electrical monitoring systems
• Energy metering applications
• Control cabinet installations requiring DIN rail mounting

Procurement Notes

Verify that the required primary current matches 800 A and secondary output is 5 A. Confirm Class 1 accuracy meets system requirements. Ensure operating frequency aligns with 50/60 Hz standards. Check mounting compatibility for DIN rail or panel integration before procurement.

Selection Notes

Select this model when an 800:5 current transformation ratio is necessary. Consider the 10 VA burden capacity for connected loads. Verify physical space constraints for window-type installation around conductors. Evaluate accuracy class requirements against specific measurement needs.

Part Context

This component belongs to the Phoenix Contact PACT MCR series of current transformers. The series offers various primary current ratings and accuracy classes. The 2277145 specifically addresses high-current industrial applications requiring precise AC current monitoring.

Replacement Considerations

Cross-reference other Phoenix Contact models in the PACT MCR-V2-4012 series for different primary current ratings. Verify identical 800:5 ratio and Class 1 accuracy if substituting. Ensure mounting style and frequency range remain compatible.
