Schneider Electric NSA160NA Industrial Circuit Breaker

Schneider Electric NSA160NA is a 4-pole molded‑case circuit breaker from the ComPacT NS family, rated for 160 A and designed for industrial power‑distribution panels. It provides thermal‑magnetic protection with a conventional Ith of 60 °C, enabling continuous operation at 160 A, and is rated for a nominal operating voltage up to 500 V (Ue) with an impulse withstand of 8 kV (Uimp) and an insulation voltage (Ui) of 500 V. The device is suitable for AC networks at 50/60 Hz and is configured for fixed panel mounting in a four‑pole arrangement (PAV). The NSA160NA offers a short‑time withstand (Icw) rated up to 1500 A, reflecting its ability to interrupt fault currents in typical industrial mains. Its compact footprint measures 90 × 120 × 82.5 mm and it weighs about 1.1 kg, making it a space‑efficient protection solution for distribution boards. As part of Schneider Electric’s NSX/NSXm/NSA platform, it is engineered to deliver reliable overload and short‑circuit protection for industrial installations, with the NSA160NA variant specifically supporting a 160 A rating for four‑pole, fixed mounting applications.
