The interrupting ratings are what you'd expect from a serious feeder breaker: 242 kA at 240 V, 187 kA at 415 V and 440 V, 121 kA at 500 V, and 9 kA at 690 V. Footprint is 138 mm wide by 248 mm tall by 110 mm deep — that's about 5.43 by 9.76 by 4.33 inches. It's a standard MCCB form factor for a 400 A frame; you're not going to have trouble finding space on a DIN rail or in a panel cutout, but verify the mounting pattern against your existing busbar or lug kit.","metaTitle":"Siemens 3VA2440-6HM32-0AA0 SENTRON MCCB, 400A, 3-Pole, ETU33","metaDescription":"Siemens SENTRON 3VA2440-6HM32-0AA0 molded case circuit breaker, 400 A continuous, 3-pole, ETU330 release.
