## Long description

The Wago TOPJOB S 3-Phase Power Distribution Terminal Block Set 16mm2 is a professional-grade solution engineered for streamlined power distribution in electrical control cabinets. This complete assembly is designed to handle 3-phase power requirements with high efficiency and reliability. By utilizing the industry-leading CAGE CLAMP connection technology, the system ensures secure, vibration-proof, and maintenance-free electrical contacts, which are essential for demanding industrial and commercial environments where uptime and safety are critical.
Advantages
The primary benefit of this terminal block set is its ability to simplify complex wiring tasks while maintaining a compact footprint within the control cabinet. The high-quality materials and robust design support a 16mm2 cross-section, allowing for significant current capacity without compromising connection integrity. Because the system is vibration-proof, it remains stable even in environments subject to mechanical stress or thermal cycling. Furthermore, the modular nature of the TOPJOB S series facilitates faster installation times and easier maintenance compared to traditional screw-type terminals.
Suitable for
Industrial control cabinet power distribution
Commercial building automation systems
3-phase motor control circuits
High-density electrical panels requiring space optimization
When it may not be suitable
This terminal block set is specifically designed for 16mm2 conductors and may not be suitable for applications requiring significantly larger or smaller wire gauges. It is intended for professional electrical installations and may not be appropriate for DIY projects where specialized DIN-rail mounting equipment is not available.
Key specifications
Connection technology: CAGE CLAMP
Cross-section: 16mm2
Configuration: 3-phase power distribution
Mounting type: DIN-rail
Design: Vibration-proof and maintenance-free
How to use
To install the terminal block set, mount the units onto a standard DIN-rail within your control cabinet. Strip the insulation from your 3-phase conductors to the recommended length. Open the CAGE CLAMP mechanism using a standard operating tool, insert the conductor fully into the terminal, and release the clamp to secure the connection. Ensure that all phases are correctly identified and connected according to your circuit diagram to maintain proper phase sequence.
What to consider before purchase
Verify that your wire gauge is compatible with the 16mm2 specification
Ensure sufficient space is available on your DIN-rail for the complete set
Confirm that the current rating meets your specific application requirements
Usage recommendations
Always ensure that the power supply is disconnected before performing any wiring operations. Use appropriate wire stripping tools to prevent damage to the conductor strands, and verify that each connection is firmly seated before energizing the system.
