Phoenix Contact 1077090 Terminal Block Accessory, 50 Pieces

The Phoenix Contact 1077090 is a professional-grade feed-through terminal block designed for efficient and secure electrical installations. This component is part of the CLIPLINE complete system, offering high reliability for industrial control systems and demanding technical environments. Each pack contains 50 pieces, featuring a distinct black and yellow color scheme for easy identification. Engineered for performance, these terminal blocks support robust connectivity while maintaining a compact footprint suitable for complex wiring setups.

Advantages

These terminal blocks utilize advanced Push-in connection technology, which allows for tool-free wiring of solid conductors or conductors with ferrules, significantly reducing installation time. The compact design is specifically optimized for front connection, making it ideal for use in confined spaces where panel density is high. Furthermore, the system includes a double function shaft and an additional test connection, providing excellent flexibility for maintenance and diagnostic testing. The product is also rigorously tested for railway applications, ensuring durability and safety in vibration-prone or high-demand environments.

Suitable for

• Industrial control systems
• Railway and transportation infrastructure
• Electrical distribution panels
• Applications requiring high-density wiring

This terminal block may not be suitable for applications requiring wire gauges outside the specified range of 0.5 mm² to 25 mm². It is also not intended for environments where the voltage exceeds 1000 V or the current exceeds 76 A, as these conditions would exceed the technical ratings of the component.

Key specifications

• Connection method: Push-in connection
• Nominal voltage: 1000 V
• Nominal current: 76 A
• Cross section range: 0.5 mm² - 25 mm² (AWG 20 - 4)
• Number of connections: 2
• Mounting type: NS 35/7,5 and NS 35/15 DIN rails
• Width: 12.2 mm
• Color: Black/Yellow

To use the terminal block, mount it onto a standard NS 35/7,5 or NS 35/15 DIN rail. Insert the prepared conductor directly into the Push-in connection point until it is securely locked. No specialized tools are required for the connection process, as the internal spring mechanism automatically secures the wire. For testing purposes, utilize the integrated double function shaft or the dedicated test connection point to perform electrical measurements without disconnecting the main wiring.

What to consider before purchase

• Verify that your conductor cross-section falls within the 0.5 mm² to 25 mm² range.
• Ensure your DIN rail type is compatible with NS 35 standards.
• Confirm that the electrical load of your circuit does not exceed the 76 A current rating.
• Check available space in your enclosure to accommodate the 12.2 mm width per terminal block.

Usage recommendations

For optimal performance and safety, ensure that conductors are properly stripped according to the manufacturer's specifications before insertion. Regularly inspect connections in high-vibration environments to maintain system integrity.
