The LV846322: Drawout mounting means the switch-disconnector slides into a fixed cradle on the chassis — no hardwiring of the main power connections during swap-out. The unit measures 441 mm wide by 439 mm high by 403 mm deep, so verify the switchgear compartment depth before committing the panel layout.
Rated for AC-23A and AC-3 utilisation categories: AC-23A covers switching of mixed resistive and inductive loads including occasional motor starts, while AC-3 is dedicated to squirrel-cage motor starting and switching off during running. The 100 kA Icu at 440 V matches the Ics rating — same 100 kA at 440 V — meaning the unit can be reclosed after a fault at its full rated breaking capacity without derating, which is uncommon at this current level. The Icw short-time withstand is 75 kA for 3 s or 100 kA for 1 s, giving selectivity margin for downstream breakers.
