Phoenix Contact UT 4 Universal Feed-Through Terminal Block, 0.14-6mm², Gray

The Phoenix Contact UT 4 is a professional-grade universal feed-through terminal block engineered for reliable electrical connectivity in demanding industrial environments. This component is designed to facilitate secure wire terminations within control cabinets and automation systems, providing a stable and durable connection point for various electrical circuits. Its compact design and gray housing allow for efficient space utilization and clear identification within complex wiring layouts.

Advantages

This terminal block utilizes a proven screw connection technology that ensures high contact force and long-term stability, even under conditions of vibration or thermal expansion. The robust construction of the housing provides excellent mechanical protection, while the design allows for quick and effortless mounting onto standard DIN rails. Its versatility is further enhanced by the wide conductor cross-section range, which accommodates both solid and stranded wires, making it a flexible solution for diverse electrical installation requirements.

Suitable for

• Industrial control cabinets and switchgear
• Automation and process control systems
• Power distribution panels
• General electrical engineering and infrastructure projects

When it may not be suitable

This terminal block is not intended for use in environments with extreme corrosive gases or high-moisture conditions without appropriate protective enclosures. It is also not suitable for applications requiring specialized connection technologies like push-in or spring-cage terminals if the installation process demands tool-free wiring.

Key specifications

• Conductor cross-section range: 0.14 mm² to 6 mm²
• Connection method: Screw connection
• Mounting type: DIN rail (NS 35)
• Color: Gray
• Material: Polyamide

How to use

To install the terminal block, snap it onto a standard DIN rail until it clicks securely into place. Strip the insulation from your conductor according to the recommended length, insert the wire into the terminal opening, and tighten the screw to the specified torque to ensure a secure mechanical and electrical connection. Multiple blocks can be placed side-by-side to create a terminal strip, and end covers or partitions should be used at the ends of the assembly to maintain safety and insulation standards.

What to consider before purchase

• Verify that the conductor size of your wiring falls within the 0.14-6 mm² range.
• Ensure your mounting rail is a standard 35 mm DIN rail.
• Check if additional accessories such as end clamps, end covers, or bridging jumpers are required for your specific circuit configuration.

Usage recommendations

Always use a calibrated torque screwdriver to tighten the terminal screws to the manufacturer's recommended torque settings to prevent damage to the conductor or the terminal block itself.
