Phoenix Contact 3044225, also known as UT 35, is a grey feed-through terminal block designed for secure conductor connection in industrial control panels and distribution assemblies. It uses a screw connection with an M6 thread and is suitable for mounting on NS 35/7.5 and NS 35/15 DIN rails.
This single-level terminal block provides two connection points on one potential and is rated for a nominal cross-section of 35 mm². It accommodates copper conductors from 1.5 mm² to 50 mm², with AWG 16 to 1/0 compatibility, making it well suited to high-current wiring applications in machinery, plant engineering, rail, and process industry installations.
The UT 35 has a 16 mm width, PA insulating material, and a UL 94 V0 flammability rating. Key electrical ratings include 1000 V nominal voltage, 125 A nominal current, and up to 150 A maximum load current when used with a 50 mm² conductor. It also features finger and back-of-hand protection, an 18 mm stripping length, and a tightening torque range of 3.2 Nm to 3.7 Nm.
Designed for use with Phoenix Contact CLIPLINE accessories, this terminal block can be paired with compatible plug-in bridges, reducing bridges, end clamps, DIN rail components, and marking systems for organised and expandable panel layouts.

What type of component is this?
It is a feed-through terminal block from the UT 35 range, designed to connect and link conductors within control panels, junction boxes and industrial electrical assemblies.
What connection method does it use?
This terminal block uses a screw connection. The screw terminal design provides a secure mechanical and electrical connection for suitable copper conductors.
What conductor sizes can it accept?
It accepts rigid copper conductors from 1.5 mm² to 50 mm² and flexible copper conductors from 1.5 mm² to 35 mm². The rated cross-section is 35 mm², equivalent to AWG 2.
What is the rated current and voltage?
For the 3044225 UT 35 terminal block, the installation data lists a rated current of 123 A and a rated voltage of 690 V. Some general catalogue data may also list ratings up to 125 A and 1000 V depending on the applicable standard and installation conditions.
What tightening torque should be used?
The recommended tightening torque range is 3.2 Nm to 3.7 Nm. Using the correct torque helps maintain reliable conductor retention and electrical contact.
How much insulation should be stripped from the conductor?
The specified stripping length is 18 mm. For flexible conductors fitted with ferrules, the ferrule length should match the required stripped length.
Which DIN rails is it designed to mount on?
This terminal block is intended for mounting on NS 35 DIN rails, including NS 35/7.5 and NS 35/15 rail profiles.
What are the approximate dimensions?
The terminal block is approximately 16 mm wide, 61.2 mm long and 65.1 mm high. Height may vary depending on whether it is mounted on an NS 35/7.5 or NS 35/15 rail.
Can it be used in potentially explosive atmospheres?
Yes, the UT 35 terminal block is listed for use in potentially explosive areas when installed correctly in a suitable enclosure. The marking includes II 2 GD Ex eb IIC Gb, with installation requirements for appropriate enclosures and clearances.
What operating temperature range is specified?
The specified operating temperature range is -60 °C to 110 °C. The final installation must remain within the required temperature limits for the enclosure and application.
What accessories are commonly used with it?
Common accessories include CLIPFIX 35 or CLIPFIX 35-5 end clamps, FBS 2-16 plug-in bridges, suitable NS 35 DIN rail, partition plates and terminal markers.
What is the commodity code for this item?
The commodity code recorded for this feed-through terminal block is 853690, which covers electrical apparatus for making connections to or in electrical circuits.
