Phoenix Contact 2771146 UKKB 5 Double-level terminal block 32A

The UKKB 5 is a double-level terminal block from Phoenix Contact's UK product family, combining two independent wiring levels into a compact 6.2 mm wide body. Rated at 500 V and 32 A, it accepts conductors from 0.2 mm² to 4 mm² via screw connection on both levels, enabling space-efficient two-circuit routing within a single terminal position.
