Phoenix Contact UTN 4 Terminal Block Blue Neutral Disconnect 250V 3245024

The Phoenix Contact UTN 4 Terminal Block Blue Neutral Disconnect 3245024 is a specialized component engineered for professional industrial control panels and power distribution systems. This blue neutral disconnect terminal block facilitates secure and reliable electrical wire connections while providing a dedicated neutral conductor disconnection function. Built for standard DIN rails, it integrates seamlessly into complex electrical architectures to ensure precise circuit management and maintenance convenience.

Advantages

This terminal block utilizes a robust screw connection mechanism that guarantees firm and vibration-resistant wire retention across a wide cross-section range. The distinct blue housing color allows for immediate visual identification of neutral circuits within a control cabinet, minimizing wiring errors during installation and servicing. Its compact width optimizes rail space, enabling high-density wiring without compromising safety or accessibility. The integrated disconnection feature simplifies testing and troubleshooting by allowing technicians to isolate the neutral conductor quickly without disconnecting surrounding wires.

Suitable for

• Industrial control panels and automation systems
• Power distribution cabinets and switchgear
• Electrical installations requiring neutral conductor isolation
• Wiring systems with conductor cross-sections from 0.14 mm² to 6 mm²

When it may not be suitable

This terminal block is not designed for applications operating outside its specified voltage rating or for direct connection to high-current power transmission lines exceeding its technical capacity. It may also be unsuitable for environments requiring push-in or spring-clamp connections if the installation standards strictly prohibit screw-type terminals.

Key specifications

• Rated voltage: 250 V
• Connection type: Screw connection
• Conductor cross-section: 0.14 mm² to 6 mm²
• AWG range: 26 - 10
• Terminal block width: 6.2 mm
• Housing color: Blue
• Mounting type: NS 35/7,5 and 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. Strip the electrical wire to the appropriate length, insert the conductor into the screw connection terminal, and tighten the screw to the recommended torque to ensure a secure mechanical and electrical bond. Use the neutral disconnect feature to isolate the circuit as needed during maintenance or testing procedures.

What to consider before purchase

• Verify that the 250 V rating matches your system requirements
• Check that your wire cross-sections fall within the 0.14 mm² to 6 mm² range
• Ensure compatibility with standard NS 35 DIN rails
• Confirm whether a blue neutral disconnect terminal aligns with your color-coding standards

Usage recommendations

Always turn off the main power supply before installing, disconnecting, or servicing the terminal block. Ensure that tightening torques for screw connections are correctly applied to prevent loose contacts or conductor damage.
