The Schneider Electric C160S4NAFM is a ComPacT NS new generation switch disconnector, 4-pole, fixed-mounted, manually operated, rated 1600 A in AC-23A duty across 220–690 V AC. The 1600 A continuous rating at 60 °C (Ith) means this part handles full-load current in a warm panel without derating — a key spec for an MCC or main switchboard position.
Rated operational current (Ie) is 1600 A in AC-23A — the heavy motor-switching duty class under IEC 60947-3. That covers switching motor loads, transformers, and highly inductive circuits up to 690 V AC. The short-time withstand (Icw) is 25 kA for 0.5 s, and the making capacity (Icm) is 52 kA at 690 V. Electrical durability is 2000 cycles at 440 V, mechanical durability 10,000 cycles. For a main disconnect that sees daily operation, that's a solid service life. The contact position indicator gives visual confirmation of open/closed state — essential for lockout/tagout procedures.
Fixed mount, front connections both top and bottom. Connection pitch is 70 mm — standard for this class of switch. Dimensions: 327 mm wide, 280 mm high, 147 mm deep. That depth (147 mm) is the panel depth you need to allow behind the door; the width (327 mm) determines the cubicle width or the number of units per section. Verify the cutout and busbar spacing against your switchboard layout before ordering.
