What this 3VA1 breaker carries
The Siemens 3VA1010-3ED32-0DH0 is a 3-pole IEC circuit breaker in the 3VA1 Frame 100 series, rated 100 A continuous with a switching capacity class N — meaning it interrupts 25 kA at 415 V without upstream fuses needing to clear first. That 25 kA figure is the ultimate short-circuit breaking capacity (Icu), so it handles the full fault current once and stays intact; for repeated faults you'd coordinate downstream devices within the let-through.
Protection and accessories on this variant
System protection TM210 here means a thermal-magnetic trip with fixed overload Ir=100 A (non-adjustable) and short-circuit pickup Ii=10×In. That fixed overload suits it for a dedicated feeder or a motor branch where the load current is known and won't change — no dial to accidentally bump. The built-in undervoltage release (UVR) coils at 208-230 V AC 50/60 Hz; if control voltage drops, the breaker opens, which is standard for emergency-stop or undervoltage protection schemes. Two auxiliary switches (HQ) plus one tripped-signal contact (HQ) give you status feedback back to the PLC or annunciator panel.
