## Summary description

The Phoenix Contact ST 4 is a 2-conductor feed-through terminal block designed for secure electrical connections. Featuring a spring-cage connection technology, it supports wire cross-sections from 0.08 to 6 mm². This blue terminal block is ideal for industrial control cabinets and automation systems, ensuring reliable signal and power distribution in demanding electrical installations.

## Long description

The Phoenix Contact ST 4 is a professional-grade 2-conductor feed-through terminal block engineered for secure and efficient electrical connectivity. Utilizing advanced spring-cage connection technology, this terminal block ensures vibration-resistant and reliable contact for various industrial applications. Its blue housing is designed for clear identification in complex control cabinets and automation systems, supporting a wide wire cross-section range from 0.08 mm² to 6 mm².
Advantages
The terminal block features a consistent double function shaft that provides significant time-saving potential for power distribution and the integration of test accessories. Its compact design combined with front-entry wiring allows for high-density installation, making it ideal for environments where space is limited. The generous wiring space accommodates conductors with ferrules and plastic collars, ensuring versatility and ease of installation. Furthermore, the component is rigorously tested for railway applications, guaranteeing high performance and durability under demanding conditions.
Suitable for
Industrial control cabinets
Automation and process control systems
Railway and transportation infrastructure
Power distribution panels
Electrical installations requiring vibration resistance
This terminal block may not be suitable for high-power applications exceeding the 32 A nominal current rating or for environments requiring specialized hazardous area protection not covered by its standard specifications. It is also not intended for direct connection to non-standard wire types that fall outside the specified 28-10 AWG range.
Key specifications
Nominal voltage: 800 V
Nominal current: 32 A
Connection method: Spring-cage connection
Number of connections: 2
Cross section range: 0.08 mm² to 6 mm² (28-10 AWG)
Width: 6.2 mm
Mounting type: NS 35/7,5 and NS 35/15 DIN rails
Color: Blue
To use the terminal block, mount it securely onto a standard NS 35/7,5 or NS 35/15 DIN rail. Strip the insulation from your conductor to the recommended length, then insert the wire into the spring-cage terminal point. The spring mechanism automatically clamps the wire, providing a secure and gas-tight connection without the need for manual screw tightening. For potential distribution, utilize the double function shaft to insert bridging components or testing probes as required by your circuit design.
What to consider before purchase
Ensure the DIN rail type matches your existing cabinet infrastructure
Verify that the wire gauge falls within the 0.08 mm² to 6 mm² range
Confirm that the 32 A current rating is sufficient for your specific load requirements
Check if the blue color coding aligns with your project's wiring standards
Usage recommendations: Always ensure that conductors are properly prepared and ferrules are used where appropriate to maintain optimal contact quality. Regularly inspect connections in high-vibration environments to ensure long-term system integrity.
