AC-23A per IEC 60947-3 covers switching of motor loads and other highly inductive circuits, so this frame is sized for high-current distribution or motor control center incoming sections where you need to make and break loads under normal service conditions, not just isolate. ## Withdrawable mounting and isolation capability Withdrawable mounting means the moving portion can be racked out for safe maintenance without disturbing the power connections — a standard requirement for switchgear where you need visible isolation or quick swap-out. The unit is certified for isolation per IEC 60947-3, with a contact position indicator and an 8 kV rated impulse withstand voltage (Uimp). No visible break, so rely on the indicator and the withdrawable position for positive isolation confirmation. ## Short-circuit performance and coordination headroom Rated short-time withstand current (Icw) is 25 kA for 0.5 s and 4 kA for 20 s — the 25 kA figure governs selectivity with upstream breakers in a distribution cascade. For a site electrical engineer building a coordination study, these are the numbers that decide whether this frame holds under the upstream protective device's clearing time. ## Environmental and mechanical durability Mechanical durability is 10,000 cycles; electrical durability is 2,000 cycles at 440 V AC.","metaTitle":"C125S4WM ComPacT NS Switch Disconnector, 1250A, 4P, Withdraw","metaDescription":"C125S4WM ComPacT NS new generation switch disconnector basic frame. 1250A AC-23A, 690V AC, 4P, withdrawable, manually operated.
