It is a manually operated, fixed-mount, 4-pole device rated for AC distribution networks at 50/60 Hz. The headline rating is 1250 A in AC-23A duty across the full voltage range from 220/240 V up to 660/690 V. AC-23A is the category for switching motor loads and other highly inductive loads — the 1250 A figure means this switch can make and break motor circuits up to that current, not just resistive loads. The conventional free-air thermal current (Ith) is also 1250 A at 60 °C, confirming the continuous current capability in a well-ventilated enclosure. The short-time withstand current (Icw) is 25 kA for 0.5 s, and the short-circuit making capacity (Icm) is 52 kA at 690 V. These numbers tell you the switch can survive and clear high-fault conditions without welding or failing — essential for selectivity coordination in a distribution board. This is a fixed-mount basic frame — no DIN-rail clip, no withdrawable cradle. It bolts directly into the switchboard or panel chassis. Both upside and downside connections are front-access, so you can land cables or busbars without reaching behind the panel. The connection pitch is 70 mm between phases, which matches standard busbar spacing for 1250 A gear. Dimensions: 327 mm wide, 280 mm high, 147 mm deep. The depth is the key clearance dimension for shallow enclosures — verify your panel depth against 147 mm plus cable bending radius before committing the BOM. The switch is designed and certified to IEC 60947-3, the international standard for disconnect switches. The manufacturer's documentation typically includes a declaration of conformity to the Low Voltage Directive and CE marking; for specific compliance packs (RoHS, REACH, UL), request them with the RFQ — they are available from the brand's support portal.","metaTitle":"Schneider Electric C125S4FM ComPacT NS Switch Disconnector,","metaDescription":"Schneider Electric C125S4FM switch disconnector basic frame, ComPacT NS new generation, 1250 A AC-23A, 4 poles, fixed, IP40, IEC 60947-3.
