UT
The Phoenix Contact UT Series comprises feed-through terminal blocks that utilize screw connection technology, offering reliable and maintenance-free conductor connections for various industrial applications. These terminal blocks are designed to accommodate a wide range of conductor cross-sections, providing flexibility and ease of installation.
Key Features:
- ✅ Screw Connection Technology: The UT Series employs a screw connection method, ensuring secure and durable connections. The Reakdyn principle, a screw locking technique developed by Phoenix Contact, prevents loosening of terminal block screws, eliminating the need for retightening.
- ✅ Versatile Conductor Accommodation: These terminal blocks can connect solid and stranded conductors without ferrules, even above the nominal cross-section, due to their large wiring space. This feature allows for universal application across various conductor types and sizes.
- ✅ Compact Design: The UT Series offers a compact, space-saving design, making it ideal for smaller control cabinets and boxes where space is at a premium.
