Frame size is 4800 A, and the interrupting ratings climb to 242 kA at 240 V, 187 kA at 415 V and 440 V, 121 kA at 500 V, and 9 kA at 690 V. That spread covers most industrial distribution voltages in North America and Europe on one breaker. ## Sizing and mounting Footprint is 138 mm wide by 248 mm tall by 110 mm deep — fits standard MCCB panel cutouts and bus-bar centers.","metaTitle":"Siemens 3VA2440-6HN32-0AH0 SENTRON MCCB, 400 A, 4800 A frame","metaDescription":"Siemens SENTRON 3VA2440-6HN32-0AH0 molded case circuit breaker, 400 A continuous, 4800 A frame, 242 kA at 240 V.
