PT
The Phoenix Contact PT Series comprises feed-through terminal blocks that utilize Push-in connection technology, offering efficient and reliable wiring solutions for various industrial applications. These terminal blocks are designed for straightforward conductor insertion, enhancing installation speed and ensuring secure connections.
- Push-in Connection Technology: The PT Series employs a direct plug-in method, allowing solid conductors or conductors with ferrules to be inserted easily without the need for tools. This design facilitates quick and reliable wiring.
- Compact Design: The terminal blocks feature a space-saving form factor, making them suitable for applications where installation space is limited.
- High Electrical Ratings: Depending on the specific model, the PT Series terminal blocks can handle nominal voltages up to 800 V and nominal currents up to 32 A, accommodating a wide range of electrical requirements.
- Versatile Conductor Compatibility: These terminal blocks support various conductor types and sizes, providing flexibility in wiring configurations.
- Integration with CLIPLINE Complete System: The PT Series is compatible with Phoenix Contact's CLIPLINE complete system, allowing for standardized bridging, marking, and testing accessories, which simplifies inventory management and enhances system modularity.
