Category B selectivity means it coordinates downstream with other breakers to isolate only the faulted branch, keeping the rest of the distribution live. Drawout mounting with front and rear connection options — the chassis stays wired while the breaker cassette slides out for maintenance or swap. Depth runs 403 mm with chassis, 300 mm without. If your switchroom runs hotter, you derate per the manufacturer's curve. Short-time withstand (Icw) of 66 kA for up to 3 seconds supports selective coordination with downstream breakers — critical for a main breaker feeding multiple feeders. Electrical durability is rated at 6000 cycles under AC-3 (motor switching) at 440/690 V, and 5000 cycles under AC-1 at 440 V. Mechanical endurance is 20,000 cycles with periodic preventive maintenance. The 25 ms maximum breaking time means fast fault clearance, limiting arc energy and thermal stress on downstream gear. Also listed to IEC 61557-12 for power metering compliance. Rated insulation voltage 1000 V AC, impulse withstand 12 kV.","metaTitle":"Schneider Electric LV848303 MasterPact MTZ2 25 H1, 2500 A Dr","metaDescription":"Schneider Electric LV848303 MasterPact MTZ2 drawout circuit breaker, 2500 A rated current, 66 kA breaking capacity at 415 V AC.
