1741935

Overview

The Phoenix Contact XT 2,5-QUATTRO RD (Part Number: 1741935) is a red feed-through terminal block designed for DIN rail mounting. It features a nominal voltage of 800 V and a nominal current rating of 24 A. The component provides four connection levels within a single position, utilizing Push-X connection technology. It supports conductor cross-sections ranging from 0.34 mm² to 4 mm² (12-20 AWG), with a rated capacity of 2.5 mm². The unit has an insulation coordination rating of 8 kV surge voltage and complies with EN 45545-2 HL3 standards.

Feature Summary

• Push-X spring connection mechanism for tool-free wiring
• Four-level multi-wire connectivity in a single position
• Compliance with railway safety standard EN 45545-2 HL3

Applications

• Railway vehicle electrical systems
• Industrial control cabinet wiring
• Signal distribution panels

Procurement Notes

Verify that the specific application requires compliance with EN 45545-2 HL3 standards, as this is a key differentiator for this part number. Confirm that the total current of all connected wires does not exceed the maximum load current of 24 A. Ensure the installation environment allows for proper heat dissipation associated with the specified current ratings.

Selection Notes

Select this model when a compact, four-level feed-through solution is required for high-density wiring applications. The Push-X technology offers faster installation compared to screw terminals. Consider the red color coding if it aligns with existing system identification schemes. Verify that the 0.34 mm² minimum wire size accommodates the smallest conductors used in the design.

Part Context

This component belongs to the XT 2,5 series by Phoenix Contact, which is engineered for robust connections in demanding environments. The 'RD' suffix indicates the red color variant. As a feed-through type, it allows continuous signal or power transmission across the terminal strip while providing access points at each level.

Replacement Considerations

Direct substitutes must match the 800 V/24 A rating, 4-level configuration, and Push-X interface. Check for identical EN 45545-2 HL3 certification if used in railway contexts. Generic terminal blocks may lack the specific push-in mechanism or fire resistance ratings.
