At 508 V AC it still holds 200 kA Icu, and at 635 V AC it's 130 kA Icu. The 100 kA Icw for 1.5 s means it withstands a short-time fault while a downstream breaker clears — critical for selective coordination in a distribution lineup. Drawout mounting means the chassis stays bolted to the switchgear while the moving portion racks out for maintenance — no need to disconnect power cables. Three-pole for three-phase distribution. Push-button control for local open/close. The 16.8 in depth, 31.07 in width, and 18.8 in height define the cutout and clearance in the switchgear lineup. Chassis-mounted in a metal-enclosed switchgear lineup — not a DIN-rail panel. The 230 mm connection pitch matches standard bus-bar spacing for high-current drawout gear. ArcBlok technology contains arc-flash energy within the housing, reducing required clearance to adjacent compartments.","metaTitle":"LV839318 Masterpact MTZ3 32 HC, 3200A, 3P Drawout, 200 kA","metaDescription":"LV839318 Masterpact MTZ3 32 HC switch disconnector, 3200A rated at 40°C, 200 kA breaking capacity at 254 V AC, 3-pole drawout.
