The 4-pole configuration with neutral on the left is the standard for three-phase plus neutral distribution. It is a basic frame — no control unit, no integral protection beyond the 40 kA integral instant protection. You add the trip unit separately to match your load's protection curve. Withdrawable mounting means the frame slides out of its cradle for inspection or swap without disturbing the bus connections — a real time-saver in a turnaround where every minute counts. Manually operated, so no motor operator for remote closing; if your BOM needs remote control, factor in the optional motor mechanism. The IP40 and IK07 ratings mean it is protected against tools and wires over 1 mm and impact energy of 2 J — standard for enclosed switchboard installation, not for open panel fronts. Mounts on a backplate in a fixed or withdrawable cradle. The 306 mm width, 260 mm height, 147 mm depth and 70 mm connection pitch are what you need to check against your switchboard cutout and busbar spacing. Certified to IEC 60947-2 for low-voltage switchgear and controlgear. Suitability for isolation is confirmed — it can be used as a disconnector under that standard. Class II on the front face means no protective earth connection needed on the operator interface. The manufacturer provides the standard compliance documentation (declaration of conformity, IEC test reports) upon request.","metaTitle":"C125H4WM ComPacT NS1250H Basic Frame, 1250 A, 70 kA at 415 V","metaDescription":"C125H4WM ComPacT NS1250H basic frame, 1250 A at 50 °C, 70 kA Icu at 415 VAC, 4P, withdrawable, manually operated.
