1474478

Overview

The Phoenix Contact 1474478 is a pluggable PCB terminal block from the ICC20-TP1,5/..L3,5 family. It features a 3.5 mm pitch and four positions for wire connections. The component supports a nominal current of 8 A and a rated voltage of 150 V. It accommodates wire cross-sections up to 1.5 mm², corresponding to AWG 24–16. The housing is made of gray polyamide, with tin-plated copper alloy contacts. Designed for through-hole mounting at a 45-degree angle, it utilizes push-in connection technology.

Feature Summary

• Push-in connection mechanism for tool-free wiring
• Interchangeable cassette system for rapid blade replacement
• Ergonomic design facilitating effortless application

Applications

• Industrial control cabinet wiring
• Signal distribution in automation systems
• Connection of PVC-insulated flat cables

Procurement Notes

Verify the specific ordering suffix matches the required configuration. Confirm that the push-in connection type aligns with the intended assembly process. Ensure the thermal rating of 105°C meets the operational environment requirements. Cross-reference the pin count and pitch against the PCB footprint specifications before procurement.

Selection Notes

Select this model when a compact 3.5 mm pitch terminal is required for low-current signal applications. The push-in technology offers faster assembly compared to screw terminals. Consider the 45-degree orientation for space-constrained board layouts. Verify compatibility with the specific wire gauge range of 16 to 24 AWG for optimal contact performance.

Part Context

This part belongs to the COMBICON Terminals S product line by Phoenix Contact. It is part of the ICC20 series, which emphasizes modular connectivity solutions. The component integrates into broader terminal block systems designed for industrial electronics. Its design focuses on reliability and ease of maintenance within complex electrical assemblies.

Replacement Considerations

Direct substitutes include other Phoenix Contact ICC20 series blocks with identical 3.5 mm pitch and 4-position configurations. Verify mechanical dimensions and electrical ratings match exactly. Alternative brands may require PCB footprint revalidation due to dimensional variances.
