Phoenix Contact 0311087 URTK/S Test disconnect terminal block

The Phoenix Contact URTK/S is a test disconnect terminal block rated at 400 V and 41 A nominal current, designed for safe testing in current transformer secondary circuits. Two test sockets for 4 mm test plugs are positioned on both sides of the disconnect point; the terminal also accepts bridge bars or screw bridges for cross-connecting adjacent blocks. Screw connection accommodates conductor cross-sections from 0.5 mm² to 10 mm² rigid via M4 thread.
