Phoenix Contact UT 16 BU Feed-Through Terminal Block, Blue, 2-Conductor, 1.5-25mm²

The Phoenix Contact UT 16 BU is a professional-grade 2-conductor feed-through terminal block designed to provide secure and reliable electrical connections in demanding industrial environments. Engineered for versatility, this terminal block utilizes a robust screw connection system that accommodates wire cross-sections ranging from 1.5 mm² to 25 mm². Its blue housing allows for easy identification in complex wiring systems, making it an essential component for organized and efficient electrical distribution.

Advantages

This terminal block offers exceptional mechanical stability and electrical conductivity, ensuring long-term performance even under heavy load conditions. The screw connection technology provides a high-contact force, which maintains a secure connection over time, reducing the need for maintenance. Its compact design allows for space-saving installation on standard DIN rails, while the high-quality materials ensure resistance to environmental stressors commonly found in industrial control cabinets.

Suitable for

• Industrial control cabinets
• Power distribution systems
• Automation technology installations
• Electrical panel building

This terminal block may not be suitable for applications requiring tool-less connection technologies, such as push-in systems, or for environments where extreme vibration levels necessitate specialized spring-loaded terminals. It is also not intended for use with conductors outside the specified 1.5 mm² to 25 mm² range.

Key specifications

• Rated voltage: 1000 V
• Rated current: 76 A
• Wire cross-section range: 1.5 mm² to 25 mm²
• Connection type: Screw connection
• Width: 12.2 mm
• Length: 55.3 mm
• Stripping length: 14 mm
• Rated surge voltage: 8 kV

How to use

To use the Phoenix Contact UT 16 BU, mount the terminal block onto a standard DIN rail until it clicks into place. Strip the insulation from your conductor to a length of 14 mm. Insert the wire into the terminal opening and tighten the screw connection using a suitable screwdriver to the recommended torque. Ensure the wire is fully seated and securely clamped before applying power to the circuit.

What to consider before purchase

• Ensure the conductor size falls within the 1.5 mm² to 25 mm² range.
• Verify that the 1000 V and 76 A ratings meet your system requirements.
• Confirm that the 12.2 mm width fits within your existing DIN rail layout.

Usage recommendations

Always ensure that the power supply is disconnected before performing any wiring work. Use appropriate tools to avoid damaging the screw heads and ensure that all connections are tightened to the manufacturer's specifications to prevent overheating or loose contacts.
