• Power quality analysis equipment

Procurement Notes

Verify the specific part number against official Phoenix Contact documentation to ensure compatibility with your system requirements. Confirm that the 1250 A primary rating and 5 A secondary output match your load characteristics. Check for any required certifications such as UL or EN 61869 depending on your regional regulations. Ensure the 42 mm bore accommodates your conductor size. Always refer to the latest datasheet for installation guidelines and environmental limits.

Selection Notes

Select this component when a high-capacity current transformer is needed for DIN rail applications. The 1250 A rating suits heavy industrial loads. The 5 A secondary output is standard for many analog meters and PLC inputs. Consider the 42 mm bore size to ensure the primary cable fits. Verify the 15 VA burden capacity matches the connected device's input impedance. The operating temperature range must suit the installation environment.

Part Context

This model belongs to the Phoenix Contact PACT MCR-V2 series, which offers various current transformer configurations. The series provides different primary ratings, bore sizes, and power ratings to suit diverse industrial needs. The 2277200 specifically addresses high-current measurement requirements with a robust DIN rail form factor.

Replacement Considerations

Check for exact part number matches in distributor catalogs. Verify that any substitute shares the same 1250 A/5 A ratio, 15 VA rating, and 42 mm bore. Ensure mechanical dimensions and DIN rail compatibility are identical. Confirm electrical performance specifications align with the original design requirements.
