The 130 kA Icu at 440 V AC (150 kA at 380/415 V) is the ultimate short-circuit breaking capacity per IEC 60947-2 — this is the SCCR that governs selectivity with the upstream breaker and determines whether the panel meets the fault-current requirement without cascading. The frame also carries a 150 kA Ics (service breaking capacity) at 380/415 V, meaning it can reclose after clearing that fault level without immediate replacement. This is a basic frame — it ships without a trip unit. The buyer must order the electronic or thermal-magnetic trip unit separately and install it into the frame. The 4-pole configuration with neutral on the left suits distribution panels where full-phase plus neutral switching is required. ## Standards and approvals — IEC and UL on the same label The C16L4 is dual-listed to EN/IEC 60947-2 (low-voltage switchgear and controlgear — circuit-breakers) and UL 60947-4-1 (motor-protective circuit-breakers). This single part covers panel builds destined for IEC markets (Europe, Asia, Middle East) and UL-recognized installations (North America). The front face carries Class II shock protection — no earth connection required on the operator-facing side. ## Mounting and integration — backplate fixed, front connections Fixed mounting on a backplate, not DIN-rail. The 140 mm width, 161 mm height, and 86 mm depth define the cutout and enclosure space — plan for a 4-pole MCCB footprint with front-facing connections on both line and load sides. The toggle control is front-accessible; the IK07 impact rating means the front face withstands a 2 J hammer blow typical of panel-door installations. IP40 protection keeps out tools and wires over 1 mm but not dust — mount inside a sealed enclosure for dusty environments.","metaTitle":"C16L4 ComPacT NSX160L Basic Frame, 160A 4P, 150kA/415V","metaDescription":"Schneider C16L4 ComPacT NSX160L basic frame. 160 A frame, 4 poles, 150 kA Icu at 415 V AC.
