Phoenix Contact UT 4 Terminal Block, 4-Conductor, 0.14-6mm2, Black

The Phoenix Contact UT 4 is a professional-grade 4-conductor terminal block engineered for secure and reliable electrical connectivity in demanding industrial environments. This component is designed to facilitate efficient power distribution and signal transmission, supporting a wide wire cross-section range from 0.14 mm² to 6 mm². Its robust screw connection technology ensures a stable contact that withstands mechanical stress, making it an essential element for control cabinets and electrical distribution systems where durability and precision are paramount.

Advantages

The terminal block features a spacious wiring area that allows for the connection of both solid and stranded conductors without the need for ferrules, even when working above the nominal cross-section. Its compact design is optimized for space-saving installations, facilitating user-friendly wiring even in confined areas. The inclusion of closed screw shafts ensures optimum screwdriver guidance, which prevents slippage and improves installation speed. Furthermore, the integrated cable entry funnel is specifically designed to accommodate conductors with ferrules and plastic collars, ensuring a secure and professional fit within the nominal cross-section range.

Suitable for

• Industrial control cabinets
• Electrical distribution systems
• Automation technology
• Wiring configurations requiring high-density connections

When it may not be suitable

This terminal block is designed for standard screw-based electrical installations and may not be suitable for environments requiring tool-free push-in connections or specialized high-vibration applications where spring-clamp technology is preferred. It is also not intended for use in environments exceeding its rated voltage of 1000 V or current of 32 A.

• Nominal current: 32 A
• Wire cross-section: 0.14 mm² to 6 mm²
• AWG range: 26 - 10
• Width: 6.2 mm
• Mounting type: NS 35/7,5 and NS 35/15 DIN rails
• Color: Black

How to use

To install the terminal block, snap it onto a standard NS 35/7,5 or NS 35/15 DIN rail. Strip the insulation from your conductor to the appropriate length and insert it into the terminal point. Use a compatible screwdriver to tighten the screw within the closed shaft until the wire is firmly secured. Ensure the connection is tight and that no bare wire is exposed outside the terminal housing. For multi-conductor configurations, follow standard electrical wiring practices to maintain organized and safe connections.

What to consider before purchase

• Verify that the DIN rail type in your cabinet matches the NS 35/7,5 or NS 35/15 standard.
• Ensure the total current and voltage requirements of your circuit do not exceed the specified 32 A and 1000 V limits.
• Check the wire gauge of your conductors to ensure they fall within the 0.14-6 mm² range.
• Consider the space available in your enclosure to accommodate the 6.2 mm width of the block.

Usage recommendations

Always ensure that the power supply is disconnected before performing any wiring or maintenance on the terminal block. Use the correct screwdriver size to avoid damaging the screw head and ensure optimal torque application.
