PHOENIX UK 3 N feed-through terminal block Grey

The PHOENIX UK 3 N feed-through terminal block in grey is a reliable electrical component designed for secure wire connections in industrial control panels, automation systems, and electrical distribution enclosures. Engineered for professional installation on DIN rails, this terminal block ensures efficient electrical conductivity, safe circuit organisation, and long-lasting durability in demanding electrical wiring applications.

Advantages

This feed-through terminal block utilizes a proven screw connection method that provides high contact stability and secure wire retention even in environments subject to vibration. The robust housing material ensures reliable electrical insulation and mechanical strength. Its compact design allows for high-density wiring configurations, optimizing space inside control cabinets and distribution boxes while maintaining clear circuit separation and easy identification.

Suitable for

• Industrial control panels and automation systems
• Electrical distribution enclosures
• DIN rail mounted electrical installations
• General wire-to-wire connection tasks in commercial settings

When it may not be suitable

This terminal block is not designed for direct outdoor exposure without a proper weatherproof enclosure. It is also unsuitable for applications requiring push-in or spring-cage wire insertion methods when screw connection is specifically excluded by project specifications.

Key specifications

• Connection method: Screw connection
• Number of connections: 2
• Wire cross section: 0.2 mm² to 4 mm²
• Wire gauge: AWG 24 - 12
• Width: 5.2 mm
• Color: Gray
• Mounting type: NS 32, NS 35/15, NS 35/7,5 DIN rails

How to use

Mount the terminal block securely onto a compatible DIN rail within your enclosure. Strip the insulation from the electrical wire to the recommended length, insert the conductor into the terminal clamping unit, and tighten the screw to the specified torque to ensure a reliable and low-resistance electrical connection. Repeat the process for the second connection to complete the circuit path as required by your wiring diagram.

What to consider before purchase

• Verify that your wire cross-section falls within the supported range of 0.2 mm² to 4 mm² or AWG 24 to 12
• Ensure your enclosure provides adequate DIN rail types such as NS 32, NS 35/15, or NS 35/7,5
• Check the spatial dimensions to ensure the 5.2 mm width fits your layout requirements

Always disconnect power to the electrical circuit before installing, maintaining, or modifying terminal blocks and wiring.
