Phoenix Contact 0421029 AKG 4 GN/YE Connection Terminal Block 300 V / 41 A

The Phoenix Contact 0421029 is a robust single-connection terminal block (AKG 4 GN/YE series) designed for secure and reliable wiring in control panels, distribution boards, and industrial switchgear. It supports up to 41 A nominal current and works at voltages up to 300 V AC — ideal for neutral conductor connections or grounding in electrical installations. The terminal accommodates conductors with cross-sections from 0.5 mm² up to 6 mm², using a screw-type connection with M4 thread and recommended tightening torque of 1.5-1.8 Nm. The unit is compact (7 mm wide), made from PA insulating material (UL 94 V-2 rated), and features the standard green/yellow color for protective or neutral terminals. Thanks to its versatile conductor range — solid, stranded, or ferruled conductors — it’s well suited for a broad variety of wiring tasks in residential, commercial, and industrial installations.
