Phoenix UTN 16 Terminal Block Blue 3245053

The Phoenix UTN 16 Terminal Block Blue 3245053 is an engineered electrical component designed for secure wire management and reliable electrical connections in industrial environments. Functioning as a neutral disconnect terminal block, it allows for effective neutral conductor disconnection and circuit isolation within control cabinets and distribution systems, ensuring stable and efficient performance across complex electrical installations.

Advantages

This terminal block utilizes a secure screw connection method that guarantees firm conductor termination and minimizes the risk of accidental loosening under vibration or thermal expansion. Its specialized design facilitates straightforward circuit isolation, enabling safer maintenance and testing procedures without the need to disconnect entire wiring assemblies. Built with high-quality insulating materials in a distinct blue color, it supports clear visual organization and phase identification in dense control panels. The component accommodates a wide range of conductor cross-sections, offering flexibility for various industrial wiring requirements while maintaining compliance with standard mounting rail systems.

Suitable for

• Industrial control cabinets and automation panels
• Power distribution systems requiring neutral conductor disconnection
• Electrical installations utilizing screw connection wiring
• Management of conductors with cross-sections from 6 mm² to 25 mm² or AWG 10 to 4

When it may not be suitable

This terminal block may not be appropriate for applications operating outside its specified electrical ratings of 400V and 76A, or in environments requiring push-in or spring-clamp connection technologies instead of screw terminals. It is also unsuitable for direct outdoor installation without a protective enclosure.

Key specifications

• Product type: Neutral disconnect terminal block
• Color: Blue
• Connection method: Screw connection
• Cross-section range: 6 mm² to 25 mm²
• AWG range: 10 to 4
• Width: 12.2 mm
• Rated voltage: 400V
• Rated current: 76A
• Mounting type: NS 35/7,5, NS 35/15 DIN rails

How to use

Mount the terminal block securely onto a compatible NS 35/7,5 or NS 35/15 DIN rail inside the enclosure. Prepare the conductor by stripping the appropriate length of insulation, ensuring the exposed wire matches the required cross-section range. Insert the stripped conductor fully into the screw connection terminal and tighten the screw to the recommended torque to achieve a reliable and permanent electrical contact. Utilize the disconnect function as needed for circuit isolation and neutral conductor maintenance.

What to consider before purchase

• Verify that the operational voltage does not exceed 400V and current remains within the 76A limit
• Ensure the available DIN rail type matches NS 35/7,5 or NS 35/15 mounting standards
• Confirm that conductor cross-sections fall between 6 mm² and 25 mm² or AWG 10 to 4
• Check that space within the control cabinet allows for the 12.2 mm width of the terminal block

Usage recommendations

Always isolate the power supply before installing, disconnecting, or performing maintenance on the terminal block to ensure electrical safety.
