The Phoenix Contact UT 10 BU Terminal Block 1000V Blue 3044188 is a high-performance feed-through terminal block designed for secure and efficient electrical connections in demanding environments. Featuring a reliable screw connection method and a distinct blue color, this component helps organize circuits effectively within industrial setups. Engineered with precision, it supports professional installations requiring dependable power distribution and long-term mechanical stability.
Advantages
This terminal block provides a large wiring space that easily accommodates both solid and stranded conductors without requiring ferrules, even for sizes above the nominal cross section. Its compact design saves valuable space while ensuring user-friendly wiring in confined areas. The integrated cable entry funnel simplifies the insertion of conductors equipped with ferrules and plastic collars. Additionally, closed screw shafts offer optimum screwdriver guidance during installation, and the unit is thoroughly tested for railway applications.
Suitable for
- Industrial control panels and electrical enclosures
- Power distribution wiring and circuit organization
- Railway applications and transportation infrastructure
- Professional electrical installations requiring a 1000 V rated voltage
When it may not be suitable
This terminal block may not be suitable for applications requiring connection methods other than screw connection, or for conductors that fall entirely outside the specified cross-section range of 0.5 mm² to 16 mm². It is also not designed for direct outdoor exposure without a proper protective enclosure.

How to use
Mount the terminal block securely onto a compatible NS 35/7,5 or NS 35/15 DIN rail inside your electrical enclosure. Strip the insulation from your conductor to the recommended length, ensuring the wire size matches the supported cross section. Insert the conductor into the cable entry funnel, making use of ferrules if desired. Use an appropriate screwdriver guided through the closed screw shaft to tighten the screw connection securely, verifying that the wire is clamped firmly before energizing the circuit.
What to consider before purchase
- Verify that the rated voltage of 1000 V and nominal current of 57 A meet your electrical system requirements
- Ensure your conductor cross sections fall within the 0.5 mm² to 16 mm² range
- Check that your mounting rail type is compatible with NS 35/7,5 or NS 35/15 standards
- Confirm that the blue color aligns with your color-coding standards for neutral or specific circuit identification
Usage recommendations
Always isolate the power supply before installing, inspecting, or modifying wiring connections on the terminal block to prevent electrical shock or equipment damage.
