It ensures efficient wiring and space-saving installation in various electrical distribution applications.

## Long description

The Phoenix Contact ST 2,5-QUATTRO is a professional-grade 4-conductor feed-through terminal block engineered for reliable electrical distribution in industrial environments. Featuring advanced spring-cage connection technology, this component allows for rapid and secure wire termination, ensuring consistent contact quality even under vibration. Its compact design and grey modular housing make it an ideal solution for space-constrained control cabinets and complex automation systems.
Advantages
The primary benefit of this terminal block is its efficient spring-cage connection system, which significantly reduces installation time compared to traditional screw terminals. The 4-conductor design facilitates easy potential distribution, allowing multiple wires to be connected to a single terminal point. Its robust construction ensures long-term operational reliability, while the standardized width allows for seamless integration into existing DIN rail assemblies, maximizing cabinet density without compromising accessibility.
Suitable for
Industrial control cabinet wiring
Automation and process control systems
Electrical distribution panels
Signal and power distribution applications
This terminal block may not be suitable for high-current applications exceeding 24 A or for environments requiring specialized hazardous area protection unless specifically rated for such conditions. It is also not intended for direct connection to high-voltage power grids beyond its 800 V nominal rating.
Key specifications
Nominal voltage: 800 V
Nominal current: 24 A
Connection method: Spring-cage connection
Number of connections: 4
Wire cross-section: 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
To use the terminal block, mount it onto a standard NS 35 DIN rail by snapping it into place. Strip the insulation from your conductor according to the specified length, then insert the wire into the spring-cage opening using a suitable screwdriver to depress the spring mechanism. Once the wire is fully inserted, release the spring to secure the connection. Ensure that the wire is firmly held and that no bare copper is exposed outside the terminal housing.
What to consider before purchase
Verify that the wire gauge falls within the 0.08 mm² to 4 mm² range.
Ensure your DIN rail type is compatible with NS 35 specifications.
Confirm that the total current load of your circuit does not exceed 24 A.
Check available space in the cabinet to accommodate the 5.2 mm width per terminal.
For optimal performance and safety, always use appropriate wire ferrules when connecting stranded conductors and ensure that all connections are inspected for mechanical integrity before energizing the system.
