The breaking capacity is substantial: 242 kA at 240 V, 187 kA at 415 V and 440 V, 121 kA at 500 V, and 40 kA at 690 V. That kind of fault-interruption headroom means this breaker can sit at the main or a high-fault subfeed without worrying about cascading failure upstream. It uses an ETU560 electronic trip unit, which gives you adjustable protection curves and communication capability — the listing confirms a communication function is present. That makes it suitable for integration into a power-monitoring or energy-management system, not just a dumb overcurrent protector. No undervoltage release or voltage trigger is included, so if you need those, plan for a separate module. Those dimensions are standard for a 400 A frame SENTRON MCCB — it will fit existing Siemens mounting plates and busbar systems. The 3-pole block occupies a single unit width in a distribution panel. Maximum power loss is 96 W — account for that heat in your enclosure ventilation calculation.","metaTitle":"Siemens 3VA2340-6JQ32-0AD0 SENTRON MCCB, 400 A, 242 kA at 24","metaDescription":"Siemens SENTRON 3VA2340-6JQ32-0AD0 molded case circuit breaker, 400 A rated, 242 kA breaking at 240 V.
