1405925

Overview

The Phoenix Contact part number 1405925 is a COMBI plug-in connector component, specifically identified as the QP 1,5/ 1-L GNYE. This single-position terminal block features a 5.2 mm pitch and utilizes a quick-connect wiring method for the first layer. It is rated for a nominal voltage of 500 V and a current capacity of 17.5 A. The unit supports wire cross-sections ranging from 0.25 mm² to 1.5 mm². Constructed with PA insulation material, it meets IEC 61984 standards and carries an UL 94 V-0 flame rating.

Feature Summary

• Features a left-side plug housing without a safety pin, designed for connection to compatible COMBI base units.
• Utilizes a quick-connect technology allowing for rapid and secure wire attachment without tools.
• Constructed from PA insulation material with a green-yellow color coding for protective earth applications.
• Complies with IEC 61984 standards for switchless capacity connectors used under no-load or no-voltage conditions.

Applications

• Industrial control cabinet wiring for signal and power distribution.
• Protective earth connections in automation systems requiring green-yellow identification.
• Integration into modular terminal block systems following IEC 61984 specifications.
• Railway vehicle electrical installations meeting DIN EN 45545-2 fire protection requirements.

Procurement Notes

Verify the specific ordering code 3051030 against the requested model 1405925 to ensure compatibility, as datasheets may list alternative identifiers for the same physical component. Confirm that the application environment does not require a safety pin, as this variant lacks one. Check for any specific packaging quantities if bulk procurement is planned, though general stock data is excluded. Ensure the receiving system accepts the open-right side design described in the product details.

Selection Notes

Select this component when a single-position, tool-free quick-connect solution is required for ground or signal lines. The 5.2 mm pitch dictates compatibility with specific COMBI series bases. Consider the 17.5 A current rating and 1.5 mm² maximum wire capacity for load requirements. The absence of a safety pin makes it suitable for applications where manual insertion security is managed by the mating base or housing structure rather than the plug itself.

Part Context

This component belongs to the Phoenix Contact COMBI series of plug-in connectors. These are standardized, switchless capacity connectors designed for use in industrial automation and control engineering. The series allows for flexible configuration of terminal blocks by combining various plug-in parts with base units. The QP designation indicates a specific type within this ecosystem, focusing on quick-connect functionality for efficient assembly.

Replacement Considerations

Direct substitutes must match the 5.2 mm pitch, single position, and quick-connect interface. Verify that any replacement also lacks a safety pin if the original design intent requires it. Ensure the new component shares the same PA insulation material and UL 94 V-0 rating for environmental compliance. Cross-reference with Phoenix Contact's official substitution lists for the QP series to confirm mechanical and electrical equivalence.
