Switch disconnector basic frame, 2500 A
That AC-23A rating covers switching of motor loads and other highly inductive circuits up to 690 V AC, so it's sized for the main disconnect in a distribution panel feeding large drives or transformers.
Rated operational current [Ie] holds at 2500 A across the full AC-23A voltage range — 220/240 V through 660/690 V — so you don't derate for higher line voltages. Short-time withstand [Icw] is 32 kA for 3 seconds, which lets the switch ride through downstream fault clearance without welding contacts. Making capacity [Icm] hits 135 kA at 690 V — that's the peak asymmetrical fault it can close into without damage, critical for coordination with upstream breakers. Impulse withstand [Uimp] is 8 kV, insulation rated [Ui] at 800 V AC. It's marked suitable for isolation per IEC 60947-3, with a visible contact position indicator — no need to verify isolation with a separate tester.
Mechanical durability is 6000 cycles; electrical durability at 440 V AC is 1000 cycles — typical for a disconnect that sees infrequent switching. Dimensions: 535 mm high, 350 mm wide, 160 mm deep. Connection pitch is 70 mm; both upside and downside connections are front-access.
