At 240 VAC it interrupts 242 kA, at 415 VAC and 440 VAC it handles 187 kA, and at 690 VAC it still clears 9 kA. That makes it suited for 4-wire systems where you need to protect the neutral against overload. Communication function is built in — no external module required for basic integration into a plant monitoring system. The breaker also reports power loss at 63.5 W maximum, which matters for enclosure thermal budgeting when you're packing several breakers into a single cabinet. ## Lifecycle and sourcing — current production, quoted to order ## Mounting and dimensions — panel fit check The 3-pole body takes up about 138 mm of rail width, so plan your enclosure fill accordingly.","metaTitle":"Siemens 3VA2440-6JQ32-0AA0 SENTRON MCCB, 400 A, 242 kA at 24","metaDescription":"Siemens 3VA2440-6JQ32-0AA0 SENTRON molded case circuit breaker, 400 A continuous, 242 kA at 240 VAC.
