Phoenix Contact 3245037 UTN 6 Neutral Disconnect Terminal Block Blue 0.2-10 mm²

The Phoenix Contact UTN 6 Neutral Disconnect Terminal Block in blue is a professional electrical component designed for secure installations and reliable wire connections. Engineered for neutral conductor disconnection, this terminal block features a reliable screw connection system that accommodates conductor cross-sections from 0.2 to 10 mm² or AWG 24 to 8. Sharing the exact same shape as standard UT terminal blocks, it ensures seamless integration and a uniform appearance within existing rail-mounted setups. It is specifically designed to facilitate efficient circuit isolation, testing, and maintenance in demanding electrical environments.

Advantages

The terminal block offers a high degree of operational safety and simplifies maintenance procedures by allowing quick and safe disconnection of the neutral conductor without altering the surrounding wiring. Its robust screw connection technology ensures secure, vibration-resistant contact that maintains consistent clamping force over time. The standardized width of 8.2 mm optimizes space on standard DIN rails while providing ample room for larger wire sizes up to 10 mm². Furthermore, the distinct blue color clearly identifies the neutral function, reducing the risk of wiring errors during installation and servicing.

Suitable for

• Industrial control panels and automation systems
• Power distribution and sub-distribution boards
• Professional electrical engineering installations
• Circuits requiring periodic neutral conductor isolation and testing

When it may not be suitable

This terminal block is not designed for direct outdoor installation without a proper protective enclosure, as it lacks weather and moisture resistance on its own. It is also unsuitable for applications that strictly require push-in or spring-cage connection methods if screw-type connections are prohibited by specific project standards.

Key specifications

• Conductor cross-section: 0.2 mm² to 10 mm²
• AWG range: 24 to 8
• Terminal width: 8.2 mm
• Color: Blue
• Connection method: Screw connection
• Mounting type: NS 35/7.5 and NS 35/15 DIN rails

How to use

Mount the terminal block onto a compatible DIN rail, such as NS 35/7.5 or NS 35/15, ensuring it is securely snapped into place alongside other modular components. Prepare the electrical wire by stripping the appropriate length of insulation to expose the conductor. Insert the stripped wire securely into the terminal opening and tighten the screw connection using the correct torque to ensure a reliable and permanent electrical contact. Use the disconnect mechanism to isolate the neutral conductor when performing maintenance or testing procedures on the circuit.

What to consider before purchase

• Verify that the conductor cross-section falls within the 0.2 to 10 mm² range required for your specific wiring setup.
• Confirm compatibility with standard NS 35 DIN rails used in your enclosure or control panel.
• Ensure that screw connection technology aligns with your installation standards and tooling availability.
• Check that the blue color coding correctly matches the neutral conductor requirements of your project.

Usage recommendations

Always de-energize the electrical circuit before installing, wiring, or operating the disconnect mechanism of the terminal block to prevent electrical shock or equipment damage.
