1408715

Overview

The Phoenix Contact model 1408715 is a COMBI plug-in connector component designed for electrical wiring systems. It features a single pole configuration with a pitch of 5.2 mm and utilizes a spring-cage connection mechanism for secure wire attachment. The unit supports rigid conductors within the range of 0.25 mm² to 1.5 mm² and flexible conductors from 0.25 mm² to 1.5 mm², accommodating AWG sizes 24 to 16. Rated for a nominal voltage of 500 V and a current capacity of 17.5 A, it withstands a rated surge voltage of 6 kV. Constructed from PA insulation material with a green-yellow color scheme, it meets IEC 61984 standards and UL 94 V0 flammability requirements.

Feature Summary

• Spring-cage connection technology enables rapid tool-assisted or manual wire insertion without screw tightening.
• Green-yellow housing provides visual identification for protective earth circuits in compliance with safety standards.
• COMBI design allows for modular expansion using compatible bridge components for multi-pole configurations.

Applications

• Protective earth connections in industrial control cabinets
• Signal distribution in automation systems requiring reliable grounding
• Integration into DIN rail mounting structures for machine building

Procurement Notes

Verify that the specific order number matches the required pin count and connection type. Confirm compatibility with existing COMBI series bridge elements if multi-pole setups are planned. Ensure the conductor cross-section falls within the specified 0.25 mm² to 1.5 mm² range for optimal contact performance. Check for any specific regional certification marks required by local installation codes.

Selection Notes

Select this component when a single-pole ground connection with spring-cage termination is required. It is suitable for applications demanding high vibration resistance compared to screw terminals. Consider the 5.2 mm pitch when designing panel layouts to ensure adequate spacing. Verify that the 500 V rating aligns with the system's maximum operating voltage and surge protection levels.

Part Context

This part belongs to the Phoenix Contact COMBI series, a standardized family of plug-in connectors widely used in European industrial automation. The series is characterized by its compact width and modular accessories, allowing for dense terminal block arrangements. Components within this family share common mechanical interfaces and connection technologies, facilitating scalable system design.

Replacement Considerations

Direct substitutes include other Phoenix Contact COMBI plugs with identical 5.2 mm pitch and spring-cage mechanics. Cross-brand replacements require verification of dimensional fit on standard DIN rails and matching electrical ratings for voltage and current capacity.

FAQ

Is this component suitable for live connection or disconnection?

No, the COMBI plug is designed for connection only under no-load or de-energized conditions as per IEC 61984 standards.

What is the minimum stripping length for the wires?

The documentation specifies a stripping length of 8 mm to 10 mm for proper insertion into the spring-cage mechanism.
