The LV847850: Drawout mounting means this terminal block is intended for the secondary disconnect plug of a drawout MasterPact breaker — it rides with the chassis, not the fixed cradle. The 6-wire configuration handles the control and indication circuits that travel with the breaker when it's racked out for maintenance. If you're replacing a damaged block on an MTZ2 or MTZ3, this is the direct fit; no adapter needed.
Schneider lists this as an active spare part (lifecycle stage: current), so it's still in regular production. No EOL notice, no last-time-buy window to watch.
