Overview
The Phoenix Contact 2277022 is a PACT MCR-V1-21-44-100-5A-1 bus-bar current transformer designed for safe and accurate measurement of high alternating currents. It features a primary current rating of 100 A AC and a secondary current output of 5 A AC, operating within a frequency range of 50 Hz to 60 Hz. The device has an accuracy class of 1 and a rated power of 2.5 VA. It includes a 20 mm bore for conductor passage and supports DIN rail or panel mounting.
Feature Summary
- Provides isolated measurement of high primary currents via a low-rating secondary output
- Ensures safety through non-intrusive bus-bar design with a fixed aperture
- Delivers precise signal conversion suitable for industrial monitoring applications
Applications
- Industrial electrical panel monitoring
- Energy management systems
- Machine tool current sensing
Procurement Notes
Verify the specific suffix codes against the manufacturer datasheet to ensure compatibility with required accuracy classes and mounting configurations. Confirm that the primary current rating matches the application load to prevent saturation. Check for any environmental certifications required for the installation site.
Selection Notes
Select this component when a 100 A primary current range is required with a standard 5 A secondary output. Ensure the installation space accommodates the 20 mm bore diameter and the physical dimensions of the housing. Verify that the system input impedance is compatible with the 2.5 VA burden rating to maintain accuracy class 1 performance.
Part Context
This model belongs to the PACT MCR-V1 series of current transformers from Phoenix Contact. These devices are engineered for integration into control cabinets and distribution boards. The series offers various primary current ratings and bore sizes to accommodate different conductor profiles while maintaining standardized secondary outputs for downstream instrumentation.
Replacement Considerations
Direct substitutes must match the 100 A primary, 5 A secondary, and 20 mm bore specifications. Verify mechanical fit and electrical burden compatibility before swapping. Cross-reference part numbers with official Phoenix Contact cross-reference lists for confirmed equivalents.
