Phoenix Contact UT 35 Feed-Through Terminal Block, 2-Conductor, Grey

The Phoenix Contact UT 35 is a professional-grade 2-conductor feed-through terminal block engineered for demanding electrical installations. Designed for reliability and safety, this component provides a secure screw connection for conductors ranging from 1.5 mm² to 50 mm². Its robust construction and grey finish make it an ideal choice for industrial control cabinets, power distribution systems, and complex electrical panels where high current capacity and organized wiring are essential.

Advantages

This terminal block stands out due to its high current-carrying capacity of 125 A and a voltage rating of 1000 V, allowing it to handle significant electrical loads with ease. The universal screw connection technology ensures a vibration-resistant and gas-tight contact, which is critical for long-term operational stability in industrial environments. Its compact design, with a width of 16 mm, helps optimize space within control cabinets, while the compatibility with standard mounting rails simplifies the installation process significantly.

Suitable for

• Industrial control cabinets
• Power distribution systems
• Heavy-duty electrical infrastructure
• Automation and control panels

When it may not be suitable

This terminal block is not intended for applications requiring push-in or spring-clamp connection technologies, as it relies exclusively on screw connections. It is also not suitable for environments where the wire cross-section exceeds the specified 50 mm² limit or for specialized hazardous area applications that require specific explosion-proof certifications not covered by this standard model.

Key specifications

• Nominal voltage: 1000 V
• Nominal current: 125 A
• Connection method: Screw connection
• Wire cross-section range: 1.5 mm² to 50 mm²
• AWG range: 16 to 1/0
• Width: 16 mm
• Height: 65.1 mm
• Mounting type: NS 35/7,5 and NS 35/15 rails
• Color: Grey

How to use

To install the terminal block, snap it onto a standard NS 35/7,5 or NS 35/15 mounting rail. Strip the insulation from your conductor according to the required length, insert the wire into the terminal opening, and tighten the screw to the specified torque to ensure a secure connection. Ensure that the terminal block is properly seated and that all connections are checked for tightness before energizing the circuit.

What to consider before purchase

• Verify that your wire gauge falls within the 1.5 mm² to 50 mm² range.
• Ensure your mounting rail type matches the NS 35 specifications.
• Check that the 16 mm width fits within your existing cabinet layout.
• Confirm that the electrical load does not exceed the 125 A nominal current rating.

Usage recommendations

Always use calibrated tools to tighten the screw connections to the manufacturer's recommended torque settings to prevent damage to the conductor or the terminal block itself.
