The LV848105 is a Schneider Electric MasterPact MTZ3 63 H2 air circuit breaker — fixed-mount, 4-pole, rated 6300 A at 40 °C. Category B selectivity (EN/IEC 60947-2) means the breaker coordinates with downstream devices so only the faulted branch opens, keeping the rest of the plant live. Rated insulation voltage is 1000 V AC, operational voltage 690 V AC. Maximum breaking time is 25 ms, closing response 80 ms. Power dissipation sits at 650 W, so panel ventilation needs to handle that heat load at full rating. This is a rear-connected, fixed-mount breaker with push-button control and no integrated control unit — it's a bare power switching and protection device, meant to be paired with a separate trip unit (Micrologic X or similar) for adjustable protection settings. The 997 mm width, 352 mm height, and 300 mm depth define the mounting footprint on rails or base plate.
Deployment context — where this breaker lives
The LV848105 is a fixed-mount air breaker for main or tie positions in low-voltage switchgear. It's not a plug-in or draw-out unit — once bolted to the busbars via rear connections, it stays. The 230 mm connection pitch and right-side neutral position are fixed; panel layout needs to accommodate that. IP30 protection means it's for indoor, dry environments only — no washdown, no outdoor exposure. Operating altitude is 0–2000 m without derating; above that, up to 5000 m, derate per the manufacturer's curve. The 650 W dissipation at full load means forced ventilation or a larger enclosure volume if the breaker is in a compact lineup.
