Phoenix Contact ST 16 BU Terminal Block, 2-Position, Blue

The Phoenix Contact ST 16 BU is a professional-grade feed-through terminal block engineered for secure and reliable electrical connections in demanding industrial environments. Utilizing advanced spring-cage connection technology, this component ensures consistent contact pressure and excellent vibration resistance, making it an ideal choice for critical control cabinets and power distribution systems. Its robust design supports a wide range of wire cross-sections, providing versatility for various electrical installation requirements.

Advantages

The terminal block features a double bridge shaft that facilitates individual chain bridging, allowing for efficient power distribution across multiple terminals. This design also supports the reduction of bridging to spring-cage terminal blocks with smaller cross-sections, enhancing the flexibility of the overall wiring architecture. As part of the CLIPLINE complete system, it integrates seamlessly with a wide range of accessories, ensuring a modular and scalable approach to complex electrical panel builds.

Suitable for

• Industrial control cabinets
• Power distribution systems
• Automation and control panels
• Electrical installations requiring vibration resistance

When it may not be suitable

This terminal block is designed for specific DIN rail mounting and may not be suitable for applications requiring direct chassis mounting or non-standard rail sizes. It is also not intended for high-frequency signal transmission where specialized shielded connectors are required.

Key specifications

• Nominal voltage: 1000 V
• Nominal current: 76 A
• Connection method: Spring-cage connection
• Number of connections: 2
• Cross-section range: 0.2 mm² to 25 mm² (AWG 24 - 4)
• Width: 12.2 mm
• Color: Blue
• Mounting type: NS 35/7,5 and NS 35/15 DIN rails

How to use

To install the terminal block, snap it onto a compatible NS 35/7,5 or NS 35/15 DIN rail. Strip the insulation from your conductor according to the specified length, then insert the wire into the spring-cage opening using a standard screwdriver to actuate the spring mechanism. Ensure the wire is fully seated to guarantee a secure connection. For bridging, insert the appropriate bridge component into the double bridge shaft to connect adjacent terminals as needed.

What to consider before purchase

• Ensure the DIN rail type in your cabinet matches the NS 35 specifications.
• Verify that the wire gauge used falls within the 0.2 mm² to 25 mm² range.
• Check the current and voltage requirements of your circuit against the 76 A and 1000 V ratings.

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 long-term reliability.
