Phoenix Contact PTFIX 4/18X1,5-NS35-FE Distribution Block Terminal Accessory

The Phoenix Contact PTFIX 4/18X1,5-NS35-FE is a professional-grade distribution block engineered for efficient electrical wiring and modular installation in industrial environments. This compact accessory facilitates organized cable management, ensuring reliable connectivity for complex control systems. Designed for DIN rail mounting, it provides a robust solution for potential distribution, combining high-density connection points with a space-saving footprint.

Advantages

This distribution block offers significant benefits for electrical panel building, including a highly compact design that maximizes cabinet space. The integrated push-in connection technology allows for rapid, tool-free wiring, which reduces installation time and labor costs. Each terminal point features dedicated test openings, enabling convenient and safe electrical measurements without disconnecting wires. Furthermore, the clear marking system ensures that all connections are easily identifiable, promoting long-term maintenance efficiency and system reliability.

Suitable for

• Industrial control cabinet wiring
• Modular power distribution systems
• Automation and instrumentation panels
• Applications requiring space-optimized potential distribution

This product may not be suitable for high-power applications exceeding the 17.5 A current rating or for environments where the conductor cross-section exceeds 2.5 mm². It is specifically designed for standard DIN rail mounting and may not be appropriate for applications requiring direct chassis mounting without the specified rail infrastructure.

Key specifications

• Nominal voltage: 500 V
• Nominal current: 17.5 A
• Connection method: Push-in connection
• Number of connections: 19
• Cross-section range: 0.14 mm² to 2.5 mm² (AWG 26 - 14)
• Mounting type: NS 35/7,5 and NS 35/15 DIN rail
• Width: 21.6 mm
• Color: Black/Yellow

To use the PTFIX distribution block, snap the unit onto a standard NS 35 DIN rail. Insert stripped conductors directly into the push-in connection points until they are securely seated. The design allows for quick expansion of potential distribution by adding further blocks as needed. Use the integrated test openings to verify voltage levels or perform continuity checks during commissioning or maintenance.

What to consider before purchase

• Ensure the total current load does not exceed the 17.5 A limit.
• Verify that your wire gauge falls within the 0.14 mm² to 2.5 mm² range.
• Confirm that your installation environment supports NS 35 DIN rail mounting.
• Check the required number of connection points for your specific circuit design.

For optimal performance and safety, ensure that all conductors are stripped to the manufacturer's recommended length before insertion. Regularly inspect connections in high-vibration environments to maintain long-term contact integrity.
