Phoenix UK3N Product Introduction

Model: UK3N

Manufacturer: Phoenix Contact

Origin: Germany

product overview

UK3N is a universal straight through terminal block developed by Phoenix Contact, specifically designed for industrial electrical systems. As one of the core products of the UK series, it has high reliability, compact structure, and wide compatibility, suitable for wire connection and management of control cabinets, automation equipment, and distribution systems. By using screw or spring clip wiring technology, stable electrical connections can be achieved while supporting flexible expansion requirements for multiple scenarios.

Main features and advantages

Reliable connection:

Using screw connection technology to ensure the wires are firmly fixed and reduce the risk of looseness, supporting mixed wiring of solid and flexible wires.

Equipped with nylon (PA66) insulation material, compliant with UL 94 V0 flame retardant standard, suitable for high temperature and high pollution environments.

Efficient organization:

Supports DIN rail installation (NS 32/35 series), compatible with U-shaped and G-type rails, and adaptable to different cabinet space requirements.

Implementing equipotential distribution through bridging components (fixed/edge plug) simplifies multi line connections.

Flexible adaptation:

Covering wire cross-sectional area of 0.2 mm ² to 4 mm ² (AWG 24-12), compatible with solid wire, multi-core wire, and cold pressed terminals.

Provide multiple colors (orange, gray, blue, etc.) for easy identification of line grouping.

Safety design:

Rated voltage 800 V AC/DC, rated current 32 A (4 mm ² wire), supports pollution level 3 and surge voltage category III.

The tightening torque range is 0.6-0.8 Nm to ensure wiring stability.
