Phoenix Contact Type-UK5N-Terminal 800 V 4mm2

The Phoenix Contact UK5N is a single-level, feed-through terminal block engineered for industrial control cabinet wiring and electrical distribution. Rated for 800 V AC/DC at 32 A nominal current, it accommodates conductor cross-sections from 0.2 mm² to 6 mm² (rigid) and 0.2 mm² to 4 mm² (flexible), making it suitable for diverse circuit configurations. The M3 screw connection design ensures secure terminations with a tightening torque of 0.6–0.8 Nm.
