2277666

Overview

Phoenix Contact part number 2277666 is a PACT MCR-V2-3015-60-750-5A-1 window-type current transformer. It features a 28 mm bore for primary conductor passage and supports an AC primary current of 750 A with a corresponding AC secondary current output of 5 A. The device operates within a frequency range of 50 Hz to 60 Hz and has a rated power capacity of 10 VA. It meets accuracy class 1 standards for measurement reliability. The unit allows for DIN rail or panel mounting, providing flexible installation options for industrial electrical monitoring systems.

Feature Summary

• Window-type design enabling non-invasive installation around existing primary conductors
• Supports standard 5 A AC secondary output for compatibility with common measurement devices
• Capable of handling high primary currents up to 750 A AC
• Offers dual mounting flexibility via DIN rail or panel attachment methods

Applications

• Industrial energy metering and power monitoring
• Electrical distribution system protection circuits
• Machine tool current surveillance
• Building management system load analysis

Procurement Notes

Verify the specific ordering code 2277666 against technical requirements before purchase. Confirm that the 28 mm bore diameter accommodates the target conductor size. Ensure the 10 VA burden rating matches the connected secondary load impedance. Check for compliance with local safety regulations and accuracy class 1 certification needs. Validate mounting style preferences for DIN rail versus panel installation.

Selection Notes

Select this component when a 750 A primary current range is required for AC measurement applications. The 5 A secondary output ensures compatibility with standard ammeters and relay inputs. Consider the 28 mm window size to ensure physical fit for the busbar or cable being monitored. Verify that the 10 VA power rating provides sufficient margin for the connected instrumentation burden. Evaluate the need for accuracy class 1 performance in the specific measurement context.

Part Context

This current transformer belongs to the Phoenix Contact PACT MCR-V2 series, designed for industrial automation and electrical engineering applications.
