The Siemens 3VA2116-0KP32-0AF0 is a 3-pole SENTRON molded case circuit breaker fitted with an ETU850 electronic trip unit, adjustable from 32 A up to 256 A. That trip unit gives you adjustable N-conductor protection (OFF, 20% to 160%) and a built-in communication function — so it talks to your BMS or PLC without an add-on module. That's a lot of fault-current headroom for a 160 A frame; you can coordinate it downstream of a transformer or upstream of a distribution panel without worrying about cascading failures.
