Its compact design ensures efficient space utilization in DIN rail mounting applications.

## Long description

The Phoenix Contact ST 1,5-QUATTRO is a professional-grade 4-conductor feed-through terminal block engineered for high-reliability electrical installations. Designed to support wire cross-sections ranging from 0.08 mm² to 1.5 mm², this component utilizes advanced spring-cage connection technology to ensure consistent, vibration-resistant contact. Its grey, compact housing is optimized for DIN rail mounting, making it an essential element for organized and efficient wiring in industrial control cabinets and automation systems.
Advantages
The primary benefit of this terminal block is its spring-cage connection system, which significantly reduces installation time while maintaining a secure electrical connection that resists mechanical shock and vibration. The 4-conductor design allows for efficient potential distribution within a minimal footprint, helping to save valuable space on the DIN rail. Furthermore, the high-quality materials used in its construction ensure long-term durability and stable performance under demanding industrial conditions.
Suitable for
Industrial control cabinet wiring
Automation and process control systems
Distribution of electrical signals and power
Applications requiring vibration-resistant connections
When it may not be suitable
This terminal block is not intended for use with wire sizes exceeding 1.5 mm² or for applications requiring currents higher than 17.5 A. It is also not suitable for environments where exposure to extreme corrosive agents or high-impact physical stress exceeds the specifications of standard industrial plastic housings.
Key specifications
Nominal voltage: 500 V
Nominal current: 17.5 A
Connection method: Spring-cage connection
Wire cross-section: 0.08 mm² to 1.5 mm²
AWG range: 28 to 16
Width: 4.2 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 standard NS 35/7,5 or NS 35/15 DIN rail. Prepare your conductors by stripping the insulation to the required length. Using a suitable screwdriver, actuate the spring-cage mechanism to insert the wire into the terminal point. Once the wire is fully inserted, release the spring to lock the conductor securely in place. Ensure that all connections are firm and that the wire is properly seated before applying power to the system.
What to consider before purchase
Verify that your wire gauge falls within the 0.08 mm² to 1.5 mm² range.
Ensure your DIN rail type is compatible with the NS 35 standard.
Check that the total current load of your circuit does not exceed 17.5 A.
Confirm that the 4.2 mm width fits your current cabinet layout requirements.
Usage recommendations
Always ensure that the power supply is disconnected before performing any wiring or maintenance tasks. Use appropriate wire stripping tools to prevent damage to the conductor strands, which could compromise the integrity of the spring-cage connection.
