The AC-23A rated operational current holds at 800 A across the full voltage range from 220/240 V up to 660/690 V AC, making it a single-rating device for motor switching and mixed loads — no derating curve to chase between line voltages. It is suitability for isolation certified to IEC 60947-3, with a visible contact position indicator confirming the break state without needing to open the panel.
Rated short-time withstand current (Icw) is 25 kA for 0.5 s, and 4 kA for 20 s, both conforming to IEC 60947-3. The 25 kA / 0.5 s figure sets the upstream protective device coordination window — a downstream fault must be cleared within that half-second to avoid damaging the switch. Rated impulse withstand voltage (Uimp) of 8 kV conforming to IEC 60947-3 covers overvoltage category III installations, typical for industrial distribution panels fed from a transformer.
Withdrawable (drawout) mounting allows the switch to be racked out of its cradle for safe maintenance or replacement without disconnecting the main busbars. IP40 protection and IK07 impact resistance suit it for general indoor panel installation where tools or incidental contact may occur, but not washdown zones. The conventional free air thermal current (Ith) is 800 A at 60 °C — no derating needed at that ambient.
