What the drawout mounting means for fit
The LV833099: Drawout mounting means this terminal block lives on the breaker cradle, not the fixed enclosure. When you rack the MTZ1 out to the test/disconnected position, the secondary wiring stays connected through the drawout contacts — no need to unlace wires for maintenance. The 6-wire count matches the standard secondary disconnect pin configuration on the MTZ1 cradle. If your BOM calls for a fixed-mount breaker, this block won't fit; it's cradle-specific.
Sourcing reality — active, but a spare part
Listed as current production. No phase-out notice, no NRND flag. Because it's a spare part (not a full breaker), it's typically ordered against a cradle or as a replacement for a damaged block on an existing MTZ1. Lead time and pricing vary by quantity — quoted against an RFQ. No direct second-source; the drawout cradle interface is proprietary to MasterPact.
