Three-pole footprint: 138 mm wide, 248 mm tall, 110 mm deep. Undervoltage release and phase failure detection are built in — no add-on modules needed for those protective functions. Two HP auxiliary switches come fitted for status feedback to the PLC or alarm panel.","metaTitle":"Siemens 3VA2440-7MN32-0BB0 SENTRON MCCB, 400 A, 3-Pole","metaDescription":"Siemens SENTRON 3VA2440-7MN32-0BB0 molded case circuit breaker, 400 A, 3-pole, ETU350M trip unit, 330 kA at 240 V.
