Terminal block PHOENIX-CONTACT UT 6-BU 2-conductor feed-through 0.2–10 mm² blue

PHOENIX-CONTACT UT 6-BU is a 2-conductor feed-through terminal block for wire cross-sections from 0.2 to 10 mm². The compact blue insulated housing provides through-termination on DIN rails and enables secure electrical connections in control cabinets, industrial automation systems and building installations. The design follows standardized dimensions for easy mounting and integration in terminal strips and allows safe conductor entry and reliable contact for stranded and solid conductors within the specified range.

Advantages

The terminal block combines a wide conductor range with a compact footprint, delivering space-efficient wiring and flexibility for mixed conductor sizes. Its secure clamping mechanism ensures low-resistance contact and vibration-resistant connections, while the insulated housing offers clear color coding and electrical isolation. The feed-through configuration simplifies wiring topology by allowing continuous signal or power paths along a DIN-rail mounted terminal strip.

Suitable for

• Control cabinets and distribution panels
• Industrial automation and machine control wiring
• Building electrical installations and lighting circuits
• Signal and power distribution on DIN-rail assemblies

Key specifications

• Conductor cross-section range: 0.2–10 mm²
• Number of conductors per terminal: 2 (feed-through)
• Insulated housing color: blue
• Mounting: DIN-rail compatible
• Connection type: secure screw or clamp-style clamping suitable for stranded and solid conductors
• Compact modular width suitable for terminal strips

How to use

Mount the terminal block onto a compatible DIN rail and tighten the fixing mechanism according to the mounting instructions. Prepare conductors by stripping insulation to the recommended length, insert each conductor into the corresponding opening and secure with the clamping screw or mechanism until a firm, vibration-resistant connection is achieved. Verify continuity and proper tightening torque where specified, then continue wiring along the terminal strip for feed-through connections.

Usage recommendations

Use the terminal block within the specified conductor cross-section range and follow applicable electrical standards for torque values and conductor preparation. Ensure the chosen mounting location provides adequate access for wiring and inspection and observe separation and marking requirements for different circuits when installing multiple terminal blocks on a DIN rail.
