It carries a continuous rating of 160 A at 50 °C, with LI protection — thermal overload (L) and fixed magnetic short-circuit (I) set at 1250 A. The 4-pole configuration protects three poles (3D) with the neutral on the left, no neutral protection (3D setting). The long-time pickup (Ir) is adjustable from 0.7 to 1.0 x In, so you can dial it down to 112 A if the load requires it. The instantaneous pickup is fixed at 1250 A — that is the magnetic trip threshold for short-circuit protection, per the LI curve. The 4-pole 3D configuration means the neutral pole is switched but not protected; the three phase poles carry the overload and short-circuit elements. ## Standards and deployment IP40 front-face protection keeps tools and fingers out but is not rated for washdown. The fixed mounting style integrates into the ComPacT NSX100...250 frame; no DIN-rail adapter needed — the breaker itself mounts to the panel or chassis.","metaTitle":"C166TM160C ComPacT NSX160 Trip Unit, 160 A, 4P 3D, TM-D","metaDescription":"C166TM160C trip unit for ComPacT NSX160, 160 A at 50 °C, thermal-magnetic LI protection, 4 poles 3D, EN/IEC 60947-2.
