Phoenix Contact 3044128 Modular Ground Terminal Block
The PHOENIX CONTACT UT 4-PE modular ground terminal block provides a reliable and secure connection for grounding applications in diverse industrial environments. Designed for use in railway systems, machine building, plant engineering, and the process industry, this terminal block offers a screw connection for robust termination and accommodates a wide range of conductor sizes, from 0.14 mm² to 6 mm². It meets stringent standards including IEC 60947-7-2 and CSA, ensuring safety and performance. The UT 4-PE's compact design (6.2 mm width) and compatibility with NS 35/7.5 and NS 35/15 mounting rails make it a versatile solution for grounding needs. Its flame retardant properties (V0 rating) and compliance with fire protection standards (DIN EN 45545-2) further enhance its suitability for demanding applications.
