For a panel running at 50 °C, plan on 570 A continuous. The interrupting capacity is the headline number here: 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 ETU850 electronic trip unit handles overcurrent protection. The breaker includes a communication function for remote monitoring. ## Lifecycle and sourcing — current production, quoted to order The maximum power loss is 162 W, which matters for thermal management inside the enclosure. If you are packing multiple breakers in a confined panel, that heat load adds up — factor it into your ventilation or derating calculation. ## Integration — footprint and panel fit The depth of 110 mm includes the front cover; allow clearance for the communication module if fitted. That is typical for a panel-mounted breaker — the enclosure provides the overall IP rating. The auxiliary contact version is 2 auxiliary switches HP (high-performance), giving you two sets of changeover contacts for status feedback.","metaTitle":"Siemens SENTRON 3VA2463-5KP32-0AB0 MCCB, 630A, 187kA at 240V","metaDescription":"Siemens SENTRON 3VA2463-5KP32-0AB0 molded case circuit breaker, 630A rated, 187kA interrupting at 240V.
