Phoenix Contact ST 6 BU Blue Terminal Block

The Phoenix Contact ST 6 BU Blue Terminal Block is a professional feed-through terminal block engineered for reliable electrical wire connections in industrial control panels and automation systems. Featuring an efficient spring-cage connection method, this component ensures secure and stable wiring while facilitating organized and simplified circuit maintenance in demanding environments.

Advantages

The compact design combined with a front connection enables user-friendly wiring in confined spaces while saving valuable panel area. A consistent double function shaft provides extensive opportunities for time-saving potential distribution and the integration of various test accessories. Furthermore, the spacious wiring area accommodates conductors with ferrules and plastic collars up to the nominal cross section, and the hardware is thoroughly tested for reliable railway applications.

Suitable for

• Industrial control panels
• Automation and distribution systems
• Railway application wiring
• Circuit organization and potential distribution

When it may not be suitable for specific projects, it is typically due to incompatible wire gauge requirements outside the supported 24 to 8 AWG range or applications demanding a connection method other than spring-cage.

How to use

To integrate the terminal block, securely mount it onto a standard NS 35/7,5 or NS 35/15 DIN rail inside the control panel. Prepare your conductor by stripping it to the appropriate length, optionally attaching a ferrule with a plastic collar, and insert it directly into the spring-cage connection point until fully seated. Utilize the double function shaft for potential distribution or testing by inserting compatible accessories as required by your circuit design.

What to consider before purchase

• Verify that your conductor cross-section falls within the 0.2 mm² to 10 mm² range
• Check that the 1000 V voltage and 41 A current ratings match your electrical system requirements
• Ensure compatibility with standard NS 35 DIN rails
• Confirm the blue color designation aligns with your circuit identification standards

Usage recommendations

Always ensure power is disconnected from the circuit before performing installation, wiring, or maintenance tasks on terminal blocks.
