What this accessory does on the MasterPact MTZ2 drawout
The LV848420 is a front bottom connection accessory for the MasterPact MTZ2 drawout breaker, 4-pole, rated 2000 A. It mounts on the downside of the breaker and provides front-access wiring terminals — meaning the cable connections land on the front face of the drawout cassette rather than the rear, which simplifies panel layout when the breaker is racked into a switchboard with limited rear clearance. The 115 mm connection pitch matches the standard MTZ2 terminal spacing, so no adapter plates or busbar re-drilling is needed.
Integration into the switchgear assembly
This is a drawout accessory — it mounts on the cassette, not the fixed portion of the switchgear. The front-access design means the cable lugs are accessible when the breaker is in the disconnected/test position, which speeds up commissioning and maintenance checks. The 115 mm pitch aligns with the MTZ2 busbar system, so an integrator can run copper or aluminum bus bars straight from the breaker terminals to the downstream distribution without extra adapters.
