The interrupting capacity reaches 187 kA at 240 V, 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 17 kA at 690 V. The overcurrent release is an ETU850 electronic trip unit. Communication function is present on this variant, and an undervoltage release (UVR) is integrated — designated as 3VA9608-0BB25 for the auxiliary trip component. Maximum power loss is 98.5 W. This is a current-production part (lifecycle stage marked as active). ## Integration into a panel — dimensions and mounting Physical footprint: 138 mm wide, 248 mm high, 110 mm deep. No auxiliary contact version is fitted on this order code (the slot is available). Trip indicator is not present on the front bezel — the ETU850 display provides fault indication via the communication interface. Phase failure detection is not a function of this release; it relies on the ETU's internal algorithms for phase imbalance. ## Environmental limits and storage Storage range is wider: -40 °C to 80 °C, which governs handling during shipping and warehouse staging, not running duty.","metaTitle":"Siemens 3VA2340-5KP32-0DA0 SENTRON MCCB, 400 A, 187 kA at 24","metaDescription":"Siemens SENTRON 3VA2340-5KP32-0DA0 molded case circuit breaker. 400 A rated, 187 kA breaking at 240 V, ETU850 release, UVR.
