1406429

Overview

The Phoenix Contact model 1406429 is a COMBIFIX plug designed for secure electrical connections within industrial control systems. It features a nominal voltage of 500 V and a rated current capacity of 24 A, ensuring reliable performance under standard operating conditions. The component utilizes a spring-cage connection method to accommodate conductor cross-sections ranging from 0.08 mm² to 4 mm², supporting both rigid and flexible wiring configurations. With a pitch of 5.2 mm and 14 positions, it provides high-density connectivity in compact enclosures. The unit is constructed from gray polyamide insulation material compliant with UL 94 V-0 flammability standards, offering robust protection against environmental factors and mechanical stress.

Feature Summary

• Spring-cage connection technology enables tool-free wire insertion and removal for simplified assembly processes.
• High-density 14-position layout allows efficient utilization of limited DIN rail space in control cabinets.
• Robust polyamide housing ensures compliance with strict safety standards including UL 94 V-0 flammability ratings.

Applications

• Industrial automation control panels requiring standardized signal distribution
• Machine building applications involving complex wiring networks
• General electrical engineering setups utilizing DIN rail mounting systems

Procurement Notes

Verify the specific part number 1406429 against official Phoenix Contact documentation to confirm compatibility with existing COMBIFIX socket assemblies. Ensure that selected conductors fall within the specified 0.08 mm² to 4 mm² range for optimal contact pressure. Check for required accessories such as marking strips or intermediate sleeves if additional organization is needed for your specific installation requirements.

Selection Notes

Select this component when a 14-position plug with 5.2 mm pitch is required for 500 V circuits carrying up to 24 A. Consider the spring-cage interface for applications demanding rapid maintenance and frequent rewiring without specialized tools. Evaluate spatial constraints within the enclosure to ensure the 72.8 mm width fits available DIN rail allocations alongside adjacent terminal blocks.

Part Context

This plug belongs to the COMBIFIX series, a modular system designed for versatile use in control cabinet construction. The series integrates various terminal types and plugs to create scalable electrical architectures. Components within this family share common mounting dimensions and connection principles, facilitating mixed installations of different terminal functions on standard NS 35/7.5 or NS 35/15 rails.

Replacement Considerations

Consult official Phoenix Contact substitution lists for verified alternatives. Generic equivalents may not match the precise 5.2 mm pitch or spring-cage mechanism specifications required for proper mating with corresponding sockets.

FAQ

What is the maximum stripping length for wires connected to this plug?

The recommended stripping length for conductors is between 8 mm and 10 mm to ensure proper engagement with the spring-cage mechanism.

Is this component suitable for use in overvoltage category III environments?

Yes, the technical data specifies an overvoltage category of III and pollution degree 3, making it suitable for distribution boards and similar applications.
