Phoenix Contact 3046173 Knife Disconnect Terminal Block
The PHOENIX CONTACT UT 4-MT-P/P-EX knife disconnect terminal block is a versatile solution for connecting wires in machine building and plant engineering applications. Its Ex nA approval makes it suitable for process technology environments requiring enhanced safety. The block's compact design maximizes space efficiency, while its 20A current carrying capacity ensures reliable performance under demanding conditions. The double bridge shaft allows for flexible potential distribution and supply, simplifying circuit design. Featuring a screw connection, it accommodates conductor cross sections ranging from 0.14 mm² to 6 mm², and is rated for a nominal voltage of 500V and a nominal current of 20A. It is mounted on NS 35/7.5 or NS 35/15 rails and offers robust construction with a V0 flammability rating.
