## Long description

The Phoenix Contact ST 2.5 QUATTRO spring-cage terminal block is a professional-grade component engineered for secure and efficient electrical distribution in industrial environments. This blue terminal block features a four-connection point design, allowing for versatile wiring configurations within a compact footprint. Built for durability, it utilizes advanced spring-cage technology to ensure consistent contact pressure and vibration-resistant connections, making it an ideal choice for demanding automation and control cabinet applications.
Advantages
The primary benefit of this terminal block is its high-density connection capability, which allows four conductors to be terminated in a single, space-saving unit. The spring-cage connection method significantly reduces installation time compared to traditional screw terminals, as it eliminates the need for torque-controlled tightening. Furthermore, the robust design ensures long-term reliability in environments subject to mechanical stress or vibration, maintaining stable electrical continuity throughout the system's lifecycle.
Suitable for
Industrial control cabinets
Automation and process control systems
Electrical distribution panels
Machine building and infrastructure projects
When it may not be suitable
This terminal block is designed for standard electrical wiring and may not be suitable for high-power applications exceeding its 24 A nominal current rating. Additionally, it is intended for use with specific DIN rail mounting systems and may not be compatible with non-standard mounting configurations without additional adapters.
Key specifications

Nominal current: 24 A
Connection method: Spring-cage connection
Number of connections: 4
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: Blue
How to use
To install the terminal block, snap it onto a compatible NS 35/7,5 or NS 35/15 DIN rail until it clicks securely into place. Strip the insulation from your conductors according to the recommended length, then insert the wire into the spring-cage opening using a standard screwdriver to actuate the spring mechanism. Once the wire is fully inserted, remove the tool to allow the spring to clamp the conductor firmly. Ensure that all connections are seated correctly to maintain electrical integrity.
What to consider before purchase
Verify that the wire gauge falls within the 28-12 AWG range.
Ensure the DIN rail type matches the mounting specifications.
Confirm that the total current load of your circuit does not exceed 24 A.
Check if the blue color coding aligns with your specific project wiring standards.
Usage recommendations
For optimal performance, ensure that conductors are properly prepared and stripped to the manufacturer's specified length. Regularly inspect connections in high-vibration environments to ensure long-term stability and safety.
