Breaking capacity lands at 187 kA at 240 V, 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 9 kA at 690 V. ## Integration dimensions Footprint: 138 mm wide, 248 mm tall, 110 mm deep. Standard DIN-rail or panel-mount installation per SENTRON 3VA family practice. ## Power loss and thermal budget Maximum power loss is 66 W. In a sealed enclosure that figure drives the internal temperature rise; account for it in the thermal budget alongside the 70 °C maximum operating ambient.","metaTitle":"Siemens 3VA2440-5HN32-0DC0 SENTRON MCCB, 400 A, 4800 A frame","metaDescription":"Siemens SENTRON 3VA2440-5HN32-0DC0 molded case circuit breaker, 3-pole, 400 A continuous, 4800 A frame, 187 kA at 240 V.
