The 4800 A frame size supports a maximum breaking capacity of 187 kA at 240 V AC, 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 9 kA at 690 V — so the same unit covers both high-fault commercial services and lower-fault industrial distribution without a frame change. Footprint: 138 mm wide, 248 mm tall, 110 mm deep — a standard SENTRON 3VA form factor that mounts on a DIN rail or panel-mount adapter in a distribution board or motor control center. Operating temperature range from -25 °C to 70 °C, storage from -40 °C to 80 °C — suitable for unconditioned enclosures in most industrial and utility environments.","metaTitle":"Siemens 3VA2440-5HN32-0AB0 SENTRON MCCB, 400 A, 4800 A frame","metaDescription":"Siemens 3VA2440-5HN32-0AB0 SENTRON MCCB, 400 A rated at 40-70°C, 4800 A frame, 187 kA at 240 V.
