Phoenix Contact PT 1.5/S BU Feed-Through Terminal Block, 500V, Blue

The Phoenix Contact PT 1.5/S BU is a professional-grade 2-conductor feed-through terminal block engineered for reliable electrical distribution in demanding environments. With its compact 3.5 mm design, this terminal block allows for high-density wiring in control cabinets, helping to optimize space without compromising on performance. It utilizes advanced push-in spring-cage connection technology, which ensures a secure, vibration-resistant contact while significantly reducing installation time compared to traditional screw terminals.

Advantages

This terminal block offers exceptional reliability due to its robust spring-cage connection mechanism, which maintains constant contact pressure regardless of thermal expansion or mechanical vibrations. The blue color-coded housing assists in clear circuit identification, enhancing safety and maintenance efficiency. Its compact footprint is specifically designed for modern automation systems where space is at a premium, allowing for more connections within the same enclosure volume. Furthermore, the high-quality materials used in its construction ensure long-term durability and consistent electrical conductivity under a rated voltage of 500 V.

Suitable for

• Industrial control cabinets
• Automation and process control systems
• Electrical distribution panels
• High-density wiring applications

When it may not be suitable

This terminal block is designed for specific wire gauges and may not be compatible with very large cross-section cables. It is intended for use within controlled industrial environments and may require additional protective housing if installed in areas exposed to extreme environmental hazards or direct moisture.

Key specifications

• Connection type: Push-in spring-cage
• Number of conductors: 2
• Rated voltage: 500 V
• Width: 3.5 mm
• Color: Blue

How to use

To use the terminal block, strip the insulation from the conductor according to the manufacturer's specified length. Insert the wire directly into the push-in opening until it is fully seated. The spring mechanism will automatically clamp the wire, creating a secure electrical connection. To release the wire, use a standard screwdriver to actuate the release lever, allowing the conductor to be removed easily.

What to consider before purchase

• Verify that the wire cross-section is compatible with the terminal's capacity.
• Ensure the DIN rail mounting system is compatible with your existing cabinet layout.
• Confirm that the 500 V rating meets the requirements of your specific electrical circuit.

Usage recommendations

Always ensure that the power supply is disconnected before performing any wiring or maintenance tasks. Use appropriate wire ferrules for stranded conductors to ensure optimal contact quality and prevent wire fraying.
