Overview
The Phoenix Contact 2277051 is a PACT MCR-V1-21-44-400-5A-1 bus-bar current transformer designed for high-accuracy measurement of alternating currents. It features a primary current rating of 400 A AC and a secondary output of 5 A AC, operating within a frequency range of 50 Hz to 60 Hz. The device achieves accuracy class 1 with a rated power of 5 VA. Physical dimensions include a length of 44 mm and a height of 66 mm. It supports mounting on DIN rails or panels and withstands maximum operating temperatures of +40°C.
Feature Summary
- Measures high alternating currents with high accuracy using a bus-bar design
- Provides standardized secondary current output for integration into monitoring systems
- Supports flexible installation via DIN rail or panel mounting styles
Applications
- Electrical instrument applications requiring precise current measurement
- Industrial energy monitoring and management systems
- Panel board integration for circuit protection and supervision
Procurement Notes
Verify the specific ordering suffix matches the required bore size and electrical ratings before purchase. Confirm that the ambient temperature conditions do not exceed the specified maximum operating limit of +40°C. Ensure the mounting environment supports either DIN rail or panel installation methods as defined by the product specifications.
Selection Notes
Select this component when a 400 A primary current rating and 5 A secondary output are required for AC measurements. Consider the physical dimensions of 44 mm length and 66 mm height for spatial constraints. Verify compatibility with 50 Hz to 60 Hz system frequencies and ensure the load does not exceed the 5 VA rated power specification.
