1408670

Overview

The Phoenix Contact model 1408670 is a COMBI series plug-in connector designed for industrial control cabinet applications. It features a 12-pole configuration with a 6.2 mm pitch and utilizes push-wire spring connection technology for rapid assembly. The component supports rigid conductors up to 6 mm² and flexible conductors up to 4 mm², accommodating AWG sizes from 28 to 10. Rated for 800 V nominal voltage and 32 A current, it meets IEC 61984 standards for load-free switching. The unit includes an integrated marking field and is constructed from gray polyamide material compliant with UL 94 V-0 flammability ratings.

Feature Summary

• Push-wire spring connection mechanism enables tool-free wiring and secure conductor retention without screw terminals.
• Integrated marking field allows for direct labeling of individual poles to streamline circuit identification.
• Compliant with IEC 61984 standard, permitting safe connection and disconnection under no-load or no-voltage conditions.

Applications

• Industrial control cabinet wiring for signal and power distribution
• Automation system interconnections requiring modular plug-in flexibility
• Machine building electrical panels utilizing COMBI terminal block systems

Procurement Notes

Verify the specific ordering suffix against the official Phoenix Contact datasheet to confirm pin count, color coding, and connection type compatibility. Ensure the selected variant matches the required conductor cross-section range and voltage rating for the intended application environment. Cross-reference the product number with current technical documentation to validate any recent design updates or material changes.

Selection Notes

Select this component when a 12-pole solution is required within the COMBI series ecosystem. Confirm that the operating environment does not exceed the rated 800 V and 32 A limits. Verify compatibility with mating socket connectors (e.g., SC series) and ensure sufficient panel space for the 74.4 mm width dimension. Check insulation clearance requirements against overvoltage category III standards.

Part Context

This plug-in connector belongs to the Phoenix Contact COMBI series, a standardized line of terminal blocks and accessories widely used in automation and process control industries. The series is characterized by its modular design, allowing seamless integration with corresponding sockets and base components to create scalable electrical connection architectures.

Replacement Considerations

Direct replacements must match the 12-pole count, 6.2 mm pitch, and push-wire connection method. Verify dimensional compatibility with existing mounting rails and mating sockets. Consult official Phoenix Contact cross-reference tools for verified alternative part numbers before implementation.

FAQ

Can this connector be switched under load?

No, according to IEC 61984, this COMBI plug-in connector is designed for load-free and voltage-free connection or disconnection only.

What is the maximum wire cross-section for flexible conductors?

The maximum cross-section for flexible conductors is 4 mm², which corresponds to AWG 12.
