Procurement Notes

Verify the specific part number against official Phoenix Contact documentation to confirm compatibility with mating COMBI sockets. Ensure that the selected component meets the required environmental ratings for the intended installation location. Cross-reference technical specifications with system design requirements before procurement.

Selection Notes

Select this component based on the requirement for a single-pole connection with a 5.2 mm pitch. Confirm that the conductor cross-section falls within the 0.25 mm² to 1.5 mm² range. Verify that the application environment aligns with the specified overvoltage category and temperature limits.

Part Context

This component belongs to the Phoenix Contact COMBI series, which provides standardized plug-in connectors for industrial applications. The series ensures interoperability between plugs and sockets, facilitating modular electrical assembly. The specific model represents a left-side plug variant designed for secure integration into DIN rail-mounted terminal blocks.

Replacement Considerations

Direct replacements must match the 5.2 mm pitch, single-pole configuration, and 500 V rating. Verify that alternative components support the same IEC 61984 compliance and quick-connect mechanism to ensure mechanical and electrical interchangeability.
