The Schneider LV848554 is an automatic spring discharge accessory — DAE type — for MasterPact MTZ2 and MTZ3 drawout circuit breakers. It releases the closing spring automatically before the breaker is withdrawn from the cradle, a required interlock step that prevents the racking mechanism from being operated with the springs charged.
Drawout mounting means this accessory installs inside the breaker cradle, not on the breaker itself. It interfaces with the racking mechanism so the spring discharge sequence happens as part of the rack-out procedure — no separate manual discharge step needed. The LV848554 locks to the circuit breaker cradle (Locking Destination: Circuit breaker) and is classified as an Installation accessory, meaning it's fitted during panel assembly or retrofit, not as a field-swappable add-on.
