Switch disconnector basic frame, 1600 A, AC-23A rated
It carries a rated operational current of 1600 A across the full AC-23A duty curve from 220/240 V up to 660/690 V, and a rated operational voltage of 690 V AC 50/60 Hz per IEC 60947-3. The AC-23A rating means this switch handles switching of motor loads or other highly inductive loads at full current — 1600 A continuous, with making and breaking capacity to match. For distribution duty, the conventional free air thermal current Ith is also 1600 A at 60 °C.
Short-circuit performance and isolation capability
Rated short-time withstand current Icw is 25 kA for 0.5 s, or 4 kA for 20 s. Short-circuit making capacity Icm reaches 52 kA at 690 V AC. The switch is suitability-for-isolation marked per IEC 60947-3, with a visible contact position indicator. Pollution degree 3 environment is covered — typical for industrial panel interiors where conductive deposits may occur.
Physical integration and environmental limits
Dimensions: 327 mm wide, 280 mm high, 147 mm deep. The fixed-mount frame accepts busbar or cable connections on a 70 mm grid. IP40 protection (finger-safe, no water ingress) and IK07 impact resistance. Electrical durability is 2000 cycles at 440 V AC; mechanical durability is 10,000 cycles.
