What this 3VA1 breaker carries
The Siemens 3VA1110-5ED32-0AA0-ZD00 is a 3-pole IEC frame 160 circuit breaker with a 55 kA Icu breaking capacity at 415 V, placing it in breaking capacity class M — the mid-range tier for this frame, sized for main or feeder protection in industrial panels where fault levels run up to that threshold. The TM210 trip unit gives fixed thermal-magnetic overload protection set at Ir = 100 A (non-adjustable) and short-circuit pickup Ii = 10 × In, so it clears fast on hard faults but rides through motor inrush within the thermal curve.
For BOM-line commitment, the key fit check is the fixed Ir = 100 A and Ii = 10×In: if your load profile needs an adjustable overload or a wider short-circuit pickup range, you would step to the TM240 or electronic trip variants in the 3VA1 family. Otherwise, this order code drops into the same 3VA1 panel footprint as the rest of the frame-160 line.
That matters for selectivity coordination downstream: you can size the upstream breaker with confidence that this unit will clear its zone before the main trips. The TM210 thermal element is fixed at Ir = 100 A — no dial to turn. That simplifies ordering (one SKU for a 100 A feeder) but means the breaker is not a general-purpose spare; it is load-specific. The magnetic pickup at 10 × In (1000 A) is typical for general distribution; if the load is a motor with high inrush, verify the starting current stays below the magnetic threshold long enough to avoid nuisance trips.
