Switch disconnector for distribution, 2000 A AC-23A, drawout
The Schneider Electric ENW24201 is an EasyPact NW switch disconnector rated for 2000 A in AC-23A duty at 690 V AC, 50/60 Hz. That AC-23A utilisation category covers switching of motor loads and other highly inductive circuits — the 2000 A figure is the operational current under those conditions, not a resistive-only rating. The 3-pole unit mounts via drawout mechanism on a rail, with rear connections arranged at a 115 mm pitch without spreader. It is certified for isolation per IEC 60947-3, meaning the open contacts provide a visible gap that meets the standard's safety disconnection requirements. Pollution degree 4 per IEC 60664-1 is the highest standard rating — it assumes conductive pollution (e.g. dust with moisture) and drives creepage distances accordingly. This makes the ENW24201 suitable for industrial environments where airborne contaminants are present, not just clean switchgear rooms. The drawout mounting means the switch body can be withdrawn from its cradle for inspection or replacement without disturbing the main power connections — a maintenance advantage in high-availability distribution panels where downtime for busbar isolation is unacceptable.
Rated short-time withstand current (Icw) is 66 kA for 1 second or 36 kA for 3 seconds at the full operating temperature range of -5 to 70 °C. The rated short-circuit making capacity (Icm) is 143 kA AC, which is the peak asymmetrical current the switch can close onto without damage. Rated impulse withstand voltage (Uimp) is 12 kV, confirming the insulation coordination for surge environments typical of industrial distribution.
Durability and lifecycle
Electrical durability at AC-23A is 6000 cycles at 440 V and 4000 cycles at 690 V without maintenance, per IEC 60947-3. Mechanical durability is 20000 cycles with maintenance or 10000 cycles without. These are the manufacturer's declared endurance figures — the switch is designed for frequent operation, not just infrequent isolation.
Physical integration and environment
Dimensions: 441 mm wide, 439 mm high, 395 mm deep. The contact position indicator gives a visual confirmation of open/closed state on the switch body itself — useful during commissioning and lockout/tagout procedures.
