Schneider Electric LV430629 NSX160NA Contactor

Schneider Electric LV430629 ComPacT NSX160NA switch disconnector, 3 poles, 160 A, is designed to isolate circuits in low-voltage distribution equipment. It is rated for up to 690 V AC (50/60 Hz) with AC-22A and AC-23A current ratings of 160 A (220–690 V) and an insulation voltage of 800 V (AC). The device mounts fixed on a backplate and is operated by a toggle control, part of the NSX family intended for reliable isolation in control panels and distribution boards. As of August 9, 2023, LV430629 was discontinued, with Schneider recommending an upgrade to the ComPacT NSX160NA 3P, 160 A model with AC22A/AC23A ratings (code C163160S). Key electrical specs include a 690 V AC rating, 160 A nominal current, 330 kA short-circuit withstand with upstream protection (3.6 kA for the switch-disconnector alone), and IEC 60947-3 conformity for isolation. The product is designed for low-voltage distribution panels and is suitable for isolation in industrial or commercial electrical installations.
