Phoenix Contact 3210499 Three-Level Terminal Block, 0.14-4mm², Grey

The Phoenix Contact 3210499 is a professional-grade three-level terminal block engineered for high-density wiring in industrial control cabinets. This component facilitates secure and organized electrical connections, supporting conductor cross-sections ranging from 0.14 mm² to 4 mm². Its compact grey housing is specifically designed to maximize space efficiency within control panels, making it an essential solution for complex electrical distribution systems where reliable connectivity is paramount.

Advantages

This terminal block utilizes the advanced Push-in connection technology, which allows for rapid, tool-free installation of solid conductors or conductors equipped with ferrules. The design is fully integrated into the CLIPLINE complete system, ensuring compatibility and ease of use. Its compact form factor and front-facing connection points are optimized for wiring in confined spaces, while the inclusion of a double function shaft and an additional test connection point simplifies maintenance and diagnostic procedures. Furthermore, the product is rigorously tested for use in demanding railway applications, confirming its durability and performance standards.

Suitable for

• Industrial control cabinet wiring
• High-density signal distribution
• Railway and transportation infrastructure
• Automation and control systems
• Applications with limited installation space

When it may not be suitable

This terminal block is not intended for high-power applications exceeding the specified 4 mm² cross-section limit. It is also not suitable for environments requiring specialized explosion-proof ratings unless specifically verified for those conditions.

Key specifications

• Connection method: Push-in connection
• Conductor cross-section: 0.14 mm² to 4 mm²
• AWG range: 26 to 12
• Width: 5.2 mm
• Color: Grey
• Mounting type: NS 35/7,5 and NS 35/15 DIN rails

How to use

To install, mount the terminal block onto a standard NS 35/7,5 or NS 35/15 DIN rail. Insert the stripped conductor or a conductor with a ferrule directly into the Push-in connection point until it is securely seated. No tools are required for the connection. For testing purposes, utilize the integrated double function shaft or the dedicated test connection point to perform electrical measurements without disconnecting the wiring.

What to consider before purchase

• Ensure the conductor size falls within the 0.14 mm² to 4 mm² range
• Verify that the DIN rail type matches the mounting requirements
• Check the available space in the cabinet to ensure the 5.2 mm width is sufficient for the required number of blocks

Usage recommendations

Always ensure that the conductors are properly stripped according to the manufacturer's specifications before insertion to maintain a secure and reliable electrical contact.
