The Siemens 3VA2563-7MP32-0AB0 is a 3-pole IEC frame 1000 molded case circuit breaker from the 3VA2 series, built for motor protection with an ETU550M electronic trip unit configured for LSI protection (long-time, short-time, instantaneous). The continuous current rating In is 630 A, with overload protection adjustable from 250 A to 630 A. The short-circuit protection settings are adjustable: Isd from 1.2 to 15 times In, and Ii from 3 to 15 times In, giving you flexibility to coordinate with downstream devices.
Integration into the panel — busbar connection and auxiliary switches
This breaker is designed for busbar connection — it comes with a busbar connection kit as part of the order code, so it's ready to plug into a standard IEC busbar system in a switchboard or MCC. It also includes two auxiliary switches (changeover type, H), which give you status feedback for remote monitoring or interlocking without needing to add separate contact blocks. The 3-pole form factor and frame 1000 footprint match the 3VA2 family mounting pattern, so panel cutouts and busbar spacing are consistent across the range.
