Phoenix Contact UT 4-QUATTRO-PE Terminal Block, 4-Conductor Protective Earth, 0.14-6mm2, Yellow-Green

The Phoenix Contact UT 4-QUATTRO-PE is a professional-grade 4-conductor protective earth terminal block engineered for reliable grounding in demanding electrical environments. This component is designed to provide a secure and stable connection for protective earth conductors, ensuring safety and compliance in industrial control cabinets, automation systems, and power distribution panels. With its robust construction and high-quality materials, it facilitates efficient electrical grounding across a wide range of wire cross-sections.

Advantages

This terminal block utilizes proven screw connection technology, which offers exceptional contact stability and long-term reliability even under conditions of high vibration. The 4-conductor design allows for efficient daisy-chaining or multi-point grounding, significantly simplifying wiring layouts within complex control panels. Its compact design helps optimize space on the DIN rail, while the distinct yellow-green color coding ensures immediate identification as a protective earth component, reducing the risk of installation errors during maintenance or system upgrades.

Suitable for

• Industrial control cabinet wiring
• Power distribution systems
• Automation and process control equipment
• Grounding applications in electrical installations

When it may not be suitable

This terminal block is specifically designed for protective earth (PE) applications and should not be used for phase or neutral power distribution. It is not suitable for environments requiring specialized explosion-proof ratings or for applications where wire sizes exceed the specified 6 mm² capacity.

Key specifications

• Connection method: Screw connection
• Number of connections: 4
• Wire cross-section range: 0.14 mm² to 6 mm²
• AWG range: 26 to 10
• Width: 6.2 mm
• Height: 46.9 mm
• Mounting type: NS 35/7,5 and NS 35/15 DIN rails
• Color: Green-yellow

How to use

To install the terminal block, snap it onto a standard NS 35/7,5 or NS 35/15 DIN rail. Strip the insulation from your protective earth conductors according to the required length and insert them into the screw terminals. Tighten the screws to the specified torque to ensure a secure mechanical and electrical connection. Ensure that the terminal block is properly grounded to the DIN rail, which acts as the primary grounding bus in most standard configurations.

What to consider before purchase

• Verify that your DIN rail type matches the mounting specifications
• Ensure the wire cross-section falls within the 0.14 mm² to 6 mm² range
• Confirm that the application requires a 4-conductor grounding point
• Check available space in the cabinet for the 6.2 mm width

Usage recommendations

Always ensure that the DIN rail is properly grounded to the main protective earth system of the installation before connecting individual components to the terminal block. Regularly inspect screw connections in high-vibration environments to maintain optimal contact integrity.
