Phoenix Contact 3031241 ST 2,5-TWIN 3-Conductor Terminal Block, Grey

The Phoenix Contact 3031241 ST 2,5-TWIN is a professional-grade 3-conductor feed-through terminal block designed to provide secure and efficient electrical connections in industrial environments. Utilizing advanced spring-cage connection technology, this terminal block allows for rapid and reliable wiring without the need for specialized tools. Its compact design and grey color make it an ideal choice for organized control cabinet layouts, facilitating clear signal and power distribution across complex automation systems.

Advantages

The primary benefit of this terminal block is its spring-cage connection system, which ensures high contact quality and vibration resistance, maintaining stable connections even in demanding industrial conditions. The 3-conductor design allows for easy potential distribution, reducing the need for additional bridging components. Furthermore, the terminal block is engineered for quick and simple mounting on standard DIN rails, significantly streamlining the assembly process for control panels and electrical distribution boards.

Suitable for

• Industrial control cabinets
• Automation and process control systems
• Electrical distribution panels
• Applications requiring vibration-resistant connections

When it may not be suitable

This terminal block is not intended for use with wire sizes exceeding 4 mm² or for applications requiring high-current power distribution beyond its 24 A rating. It is also not suitable for environments where specialized hazardous area certifications beyond standard industrial ratings are required.

Key specifications

• Nominal voltage: 800 V
• Nominal current: 24 A
• Connection method: Spring-cage connection
• Number of connections: 3
• Cross-section range: 0.08 mm² to 4 mm²
• AWG range: 28 to 12
• Width: 5.2 mm
• Mounting type: NS 35/7,5 and NS 35/15 DIN rails
• Color: Grey

How to use

To install the terminal block, snap it onto a compatible NS 35 DIN rail until it is securely locked in place. Strip the insulation from your wire to the recommended length and insert the conductor into the spring-cage terminal point. The spring mechanism automatically clamps the wire, ensuring a gas-tight and vibration-proof connection. To remove or adjust the wire, use a standard screwdriver to actuate the spring release.

What to consider before purchase

• Ensure the wire cross-section falls within the 0.08 mm² to 4 mm² range.
• Verify that the DIN rail type matches the NS 35/7,5 or NS 35/15 standard.
• Check that the total current load of the circuit does not exceed 24 A.

Usage recommendations

For optimal performance and safety, always ensure that the wires are stripped to the correct length and fully inserted into the terminal point. Regularly inspect connections in high-vibration environments to ensure long-term system integrity.
