If this breaker lands in a hot switchroom or a non-climate-controlled enclosure, the 70 °C figure (450 A) is the one that governs the load it can actually carry — not the 630 A nameplate. ## Communication and auxiliary contact configuration This MCCB includes a communication function, which on the 3VA platform typically means it can interface with a fieldbus or Ethernet gateway for power monitoring and remote trip indication — useful for a plant-wide energy management system or a PLC-driven shutdown sequence. The auxiliary contact version is specified as 1 auxiliary switch + 1 trip alarm switch HP, giving one N.O./N.C. set for status and a separate alarm contact that changes state only on a trip event, not on manual open. The basic switch (the breaker mechanism without the trip unit) is order code 3VA2463-5KP32-0AA0, and the integrated auxiliary trip is 3VA9608-0BB11 — these are the spare-part codes if the ETU850 or the auxiliary switch needs replacement separately. ## Where this MCCB fits in the system A 630 A MCCB with 187 kA interrupting capacity and electronic trip is typically the main breaker in a 240 V or 415 V distribution panel feeding downstream subpanels, motor control centers, or large single loads (chillers, compressors, large pumps). The ETU850 supports adjustable long-time pickup and delay, short-time pickup and delay, instantaneous pickup, and ground-fault — so it can be coordinated with downstream breakers and fused switches.","metaTitle":"Siemens 3VA2463-5KP32-0AG0 SENTRON MCCB, 630 A, 187 kA","metaDescription":"Siemens 3VA2463-5KP32-0AG0 SENTRON molded case circuit breaker, 630 A rated, 187 kA interrupting at 240 V.
