Phoenix Contact UTTB 4 Double-Level Terminal Block, 6mm², Grey

The Phoenix Contact UTTB 4 is a professional-grade double-level terminal block engineered for high-density wiring in industrial control cabinets. With a compact design and a 6mm² cross-section, this component facilitates efficient electrical distribution while maximizing space on standard DIN rails. Its robust screw connection technology ensures reliable, vibration-resistant contact for demanding electrical systems.

Advantages

This terminal block offers significant flexibility through its dual-level architecture, allowing for high-density wiring in limited spaces. The inclusion of two function shafts per level enables rapid potential distribution, while the optional vertical bridge allows for seamless level interconnection. The design prioritizes clarity and maintenance, featuring large-surface labeling areas for easy identification of terminal points. Furthermore, the unit is rigorously tested for railway applications, ensuring durability and safety in harsh environments, and supports complex routing configurations by allowing bridging between non-adjacent blocks.

Suitable for

• Industrial control cabinet wiring
• Electrical distribution systems
• Railway infrastructure projects
• High-density signal and power routing

When it may not be suitable

This terminal block is designed specifically for standard DIN rail mounting and may not be suitable for applications requiring direct chassis mounting without an adapter. It is also not intended for high-current applications exceeding the specified cross-section capacity.

Key specifications

• Connection method: Screw connection
• Cross-section range: 0.14 mm² to 6 mm²
• AWG range: 26 to 10
• Width: 6.2 mm
• Mounting type: NS 35/7,5 and NS 35/15 DIN rails
• Color: Grey

How to use

Installation is performed by snapping the terminal block onto a standard NS 35 DIN rail. Wires are inserted into the terminal points and secured using the integrated screw mechanism, ensuring a firm mechanical and electrical connection. For potential distribution, jumpers or vertical bridges can be inserted into the designated function shafts. Labeling strips can be applied to the provided surface areas to maintain organized documentation of the wiring layout.

What to consider before purchase

• Ensure the DIN rail type matches the NS 35/7,5 or NS 35/15 standard.
• Verify that the wire gauge falls within the 0.14 mm² to 6 mm² range.
• Check if additional accessories like end covers or vertical bridges are required for your specific circuit design.

Usage recommendations

Always ensure that all screw connections are tightened to the manufacturer's specified torque to maintain long-term electrical integrity and prevent overheating in high-load scenarios.
