The Siemens 3VA1132-3GD42-0AA0-ZD00 is a 4-pole IEC frame 160 molded case circuit breaker (MCCB) from the 3VA1 series, rated for line protection with a fixed 32 A thermal-magnetic trip unit (TM210).
In a typical 400 V industrial supply with a transformer rating under 1 MVA, that's enough headroom for downstream feeder protection — you won't need a current-limiting upstream breaker just to protect this one. The fixed 32 A overload setting (Ir = 32 A) and fixed short-circuit pickup (Ii = 10 x In = 320 A) mean the trip curve is non-adjustable. That simplifies ordering but locks the coordination: verify the 320 A magnetic pickup doesn't overlap with the inrush of the load (motors, transformers) you're protecting. The TM210 designation indicates a thermal-magnetic trip with a 10x In magnetic threshold — standard for general-purpose feeder and branch protection.
