Procurement Notes
Verify component status carefully as this part number is listed as obsolete or no longer in the product range by the manufacturer. Sourcing may require checking distributor clearance stock or authorized surplus channels. Confirm compatibility with existing system requirements before procurement due to potential end-of-life constraints.
Selection Notes
Select this model specifically when a 1,600 A primary current rating and 5 A secondary output are required for non-invasive monitoring. Ensure the available space accommodates the specified dimensions and that the mounting environment supports DIN rail installation. Verify that the load impedance does not exceed the 10 VA rated power capability.
Part Context
This component belongs to the PACT MCR-V2 series of plug-on converters manufactured by Phoenix Contact. These devices are categorized as industrial current transformers designed for signal conversion. The specific model integrates precise magnetic coupling technology to step down high primary currents for standard instrumentation input.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided documentation. Due to the obsolete status, direct replacements should be evaluated based on matching electrical parameters such as 1,600 A primary current, 5 A secondary output, and 10 VA burden capacity.
