The ArcBlok technology contained inside limits arc energy during interruption, which reduces stress on downstream components and speeds fault clearing. The 800 A frame rating sets the continuous current limit at 40 °C ambient — derate above that per the thermal curve. The 200 kA Icu at 240 V AC means this breaker can safely interrupt a fault up to 200,000 symmetrical amperes without external fusing; at 480 V the same rating drops to 150 kA, still well above typical service-entrance fault levels. The 30 kA Icw for 0.5 s gives short-time withstand for selective coordination downstream — the breaker holds in during a delayed trip to let a branch device clear first. Mechanical durability of 12,500 cycles and electrical durability of 2,800 cycles under ANSI C37.50 define the maintenance interval for drawout racking operations. Drawout mounting means the breaker chassis is fixed to the panel base plate rails, and the removable cradle slides in and out for service without disturbing line or load connections. The 4.5 in (115 mm) connection pitch matches standard bus-bar spacing for switchgear assemblies. Overall dimensions: 17.5 in wide × 17.3 in tall × 16.8 in deep — verify the panel cutout and clearance for the racking mechanism before specifying.","metaTitle":"Schneider LV839151 MasterPact MTZ2 800A 3P Drawout Circuit B","metaDescription":"LV839151 MasterPact MTZ2 800A 3-pole drawout circuit breaker. 200 kA Icu at 240 VAC UL 489.
