Available. The Phoenix Contact ST 6-PE is a protective conductor terminal block designed for secure grounding in industrial applications. This terminal block features two connections with a spring-cage connection method, accommodating conductor cross-sections from 0.2 mm² to 10 mm². It is mounted on NS 35/7.5 and NS 35/15 DIN rails and is characterized by its green-yellow color. The ST 6-PE is suitable for use in the railway industry, machine building, plant engineering, and process industry sectors. It complies with IEC 60947-7-2 standards and offers a rated surge voltage of 8 kV, ensuring reliable performance in demanding environments. The terminal block is constructed from polyamide (PA) with a flammability rating of UL94 V0, providing durability and safety. Its compact dimensions—8.2 mm in width and 69.5 mm in height—make it ideal for space-constrained installations. The ST 6-PE is also tested for railway applications, meeting the requirements of DIN EN 50155 for oscillation and shock resistance, making it suitable for use in rolling stock applications.
