The Schneider Electric ENW24263 is a 4-pole switch disconnector from the EasyPact NW range, rated for 1250 A in AC-23A duty at 690 V AC. The 50 kA rated short-time withstand current (Icw) for 1 second tells you it can ride through a fault long enough for an upstream breaker to clear, which is the kind of coordination a distribution panel needs. It's built for continuous duty, drawout mounting on a rail, with rear vertical or horizontal connection positions. The 395 mm depth and 556 mm width give you the envelope for panel layout — this isn't a compact unit, it's a main breaker-sized disconnector for a switchboard.
The headline number is 1250 A AC-23A at 690 V — that's the motor-switching current, not a resistive-heater rating. The 105 kA making capacity (Icm) means it can close onto a short-circuit without welding contacts, which is critical for a switch that may be called on to energize a faulted bus. That's unusual for a switch disconnector; most stop at PD3. The 12 kV impulse withstand voltage (Uimp) backs this up: it handles surge events common in industrial power systems without flashover. It's suitable for isolation per IEC 60947-3, with a visible contact position indicator. That means a qualified worker can verify the circuit is open by looking at the switch, not relying on a pilot light or meter.
Drawout mounting on a rail means the switch can be racked out for maintenance or replacement without disconnecting the main bus bars — a standard feature for switchboard-grade disconnectors. The right-side neutral position and 115 mm connection pitch without spreader tell you the bus bar layout needs to match this footprint. IP40 protection means it's indoor-only, no washdown. The 6000-cycle electrical durability at 440 V and 4000 cycles at 690 V (AC-23A) gives a realistic service life for a main disconnector — not a daily-operating contactor, but fine for infrequent switching duty.
