Phoenix Contact 2770011 UKK 3 Double-level terminal block 24A

The Phoenix Contact UKK 3 is a double-level terminal block that routes two independent circuits within a compact 5.2 mm wide body. Rated at 500 V and 24 A, it uses M3 screw connections on both levels to accept rigid conductors from 0.2 mm² to 4 mm², enabling two separate potentials per terminal position for space-efficient panel wiring.
