The Phoenix Contact 1047459 PTFIX 4/18X1.5-NS35 distribution block is a professional-grade component engineered for efficient power distribution and organized electrical wiring in industrial environments. This yellow terminal block is designed for mounting on standard DIN rails, offering a compact footprint that maximizes space within control cabinets and automation systems. With its robust construction and reliable push-in connection technology, it ensures secure and durable electrical contacts for demanding applications.

Advantages

This distribution block offers significant advantages for electrical installations by providing a space-saving solution that simplifies complex wiring tasks. The integrated push-in connection technology allows for rapid, tool-free conductor insertion, which reduces assembly time and labor costs. Its compact design is specifically optimized for high-density control panels where space is at a premium. Furthermore, the inclusion of test openings at every terminal point facilitates convenient maintenance and troubleshooting, while the clear marking system ensures that all connections remain organized and easily identifiable during operation.

Suitable for

• Industrial control panels and automation systems
• Power distribution in electrical cabinets
• Applications requiring high-density wiring
• Systems where quick and reliable connection points are essential

This distribution block may not be suitable for applications involving high-power circuits exceeding the nominal current rating of 17.5 A or voltages above 500 V. It is also not intended for use in environments with extreme vibration or corrosive conditions that exceed the specifications of standard DIN rail-mounted terminal components.

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: Yellow

How to use

To install the distribution block, snap it onto a standard NS 35 DIN rail. Prepare your conductors by stripping the insulation to the required length. Insert the solid or ferruled conductor directly into the push-in terminal point until it is fully seated. For stranded wires without ferrules, use a screwdriver to actuate the release mechanism if necessary. Ensure that all connections are secure and that the wiring is organized according to your system schematic. Use the integrated test openings to verify electrical continuity during the commissioning process.

What to consider before purchase

• Verify that the current and voltage requirements of your circuit do not exceed the block's ratings.
• Ensure your DIN rail type is compatible with NS 35 standards.
• Check the wire gauge of your conductors to ensure they fall within the 0.14 mm² to 2.5 mm² range.
• Consider the total number of connections required for your specific application.

Usage recommendations

For optimal performance and safety, always ensure that conductors are properly prepared before insertion. Use appropriate wire ferrules for stranded conductors to maintain the integrity of the push-in connection. Regularly inspect the terminal block during routine maintenance to ensure that all connections remain tight and free from environmental debris.
