PHOENIX CONTACT UTTB 2,5 Double-Level Terminal Block, 2.5 mm²

The PHOENIX CONTACT UTTB 2,5 is a professional-grade double-level terminal block engineered for high-density wiring in industrial control cabinets and automation systems. This component allows for efficient space utilization by providing two connection levels within a compact 5.2 mm width, making it an ideal solution for complex electrical installations where panel space is limited. The block utilizes robust screw connection technology to ensure reliable, vibration-resistant, and long-lasting electrical contacts for both solid and flexible conductors.

Advantages

The primary benefit of this double-level terminal block is its ability to double the wiring density compared to standard single-level blocks without increasing the footprint on the DIN rail. The high-quality screw connection system provides a secure mechanical and electrical bond that maintains integrity even in demanding industrial environments. Its versatile design supports a wide range of conductor cross-sections, offering flexibility for various control and power distribution tasks. The grey housing is constructed from durable materials designed to withstand standard industrial operating conditions.

Suitable for

• Industrial control cabinet wiring
• Automation and process control systems
• Power distribution panels
• High-density electrical signal routing

When it may not be suitable

This terminal block is not intended for applications requiring high-current connections exceeding 20 A or voltages higher than 500 V. It is also not suitable for environments where push-in or spring-cage connection technology is specifically mandated by project requirements.

Key specifications

• Rated voltage: 500 V
• Rated current: 20 A
• Conductor cross-section (solid/flexible): 0.14 mm² to 4 mm²
• Width: 5.2 mm
• Length: 69.9 mm
• Connection method: Screw connection
• Stripping length: 9 mm
• Rated surge voltage: 6 kV

How to use

To install the terminal block, snap it onto a standard DIN rail. Strip the insulation from your wires to a length of 9 mm. Insert the conductor into the desired terminal level and tighten the screw to the specified torque to ensure a secure connection. Ensure that the wire is fully seated within the clamp before tightening. The double-level design allows for independent wiring on both the upper and lower levels, facilitating organized cable management.

What to consider before purchase

• Verify that the 5.2 mm width fits your current DIN rail layout.
• Ensure the 20 A current rating is sufficient for your specific circuit requirements.
• Check that your wire gauges fall within the 0.14 mm² to 4 mm² range.
• Confirm that screw connection technology meets your installation standards.

Usage recommendations

For optimal performance and safety, always use a calibrated screwdriver to tighten the screw connections. Ensure that the terminal block is properly secured on the DIN rail and that all wires are routed to minimize mechanical strain on the connection points.
