Phoenix Contact 3215915 Protective Terminal Block, 16mm2, Green-Yellow

The Phoenix Contact 3215915 is a professional-grade protective terminal block designed to provide a reliable grounding connection in electrical systems. Engineered for industrial applications, this component features a robust screw connection system that ensures high contact quality and mechanical stability. Its design is specifically optimized for mounting on standard DIN rails, making it a versatile solution for control cabinets and distribution panels where safety and electrical integrity are paramount.

Advantages

This protective terminal block offers exceptional durability and ease of use in demanding industrial environments. The screw connection technology provides a secure, vibration-resistant contact that maintains its integrity over long periods of operation. Its clear green-yellow color coding adheres to international standards for protective earth conductors, allowing for quick identification and reducing the risk of wiring errors during installation or maintenance. The compact design allows for efficient space utilization within crowded electrical enclosures while supporting a wide range of conductor cross-sections.

Suitable for

• Industrial control cabinets
• Power distribution systems
• Grounding applications in electrical panels
• Automation and machinery control systems

This terminal block may not be suitable for applications requiring high-speed plug-in connections or environments where tool-less installation is a primary requirement. It is also not intended for use with non-grounding electrical circuits or in environments exceeding the specified mechanical and thermal ratings.

Key specifications

• Connection method: Screw connection
• Number of connections: 2
• Cross-section range: 1.5 mm² to 25 mm²
• AWG range: 16 to 4
• Width: 12.2 mm
• Mounting type: NS 35/7,5 and NS 35/15 DIN rails
• Color: Green-yellow

To install the terminal block, snap it onto the appropriate NS 35 DIN rail until it clicks into place. Strip the insulation from your grounding conductor according to the manufacturer's guidelines, insert the wire into the terminal opening, and tighten the screw to the specified torque to ensure a secure connection. Ensure that the terminal is properly seated and that the grounding path is continuous throughout the assembly.

What to consider before purchase

• Verify that the DIN rail type matches the mounting specifications
• Ensure the conductor cross-section falls within the 1.5 mm² to 25 mm² range
• Confirm that the space available in the cabinet accommodates the 12.2 mm width
• Check local electrical regulations regarding protective earth connections

For optimal performance and safety, always use the correct screwdriver size and tighten connections to the recommended torque values. Periodically inspect the terminal block for signs of wear or loose connections during routine maintenance cycles.
