The Schneider Electric LV846173 is a MasterPact MTZ2 drawout circuit breaker rated 1600 A at 40 °C, with a 100 kA ultimate breaking capacity (Icu) at 440 V AC. The 100 kA service breaking capacity (Ics) at the same voltage tells you it can reclose after a fault at full rating, not just survive it once. This is a Category B breaker, meaning it's designed with intentional short-time delay for selective coordination — you can set it to ride through downstream faults so only the nearest device opens, keeping the rest of the plant online. The 100 kA short-time withstand (Icw) for 1 second backs that up: it holds the fault current for the coordination interval without damage. The drawout mounting means the breaker chassis stays wired in the switchgear; the removable cradle lets you rack the breaker out for maintenance or replacement without disturbing the power connections. Front and rear connection options give flexibility for cable or busbar entry in new builds or retrofits.
Integration — what fits in the footprint
The drawout cradle mounts on rails or a base plate. Overall dimensions: 441 mm wide, 439 mm high, 403 mm deep. IP30 protection is typical for enclosed switchgear — the breaker is not intended for open-panel or washdown environments.
