The Siemens 3VA1010-2ED36-0HH0 is a 3-pole IEC frame 100 circuit breaker rated 100 A continuous, with a breaking capacity of 16 kA at 415 V (switching capacity class B). It's built around the TM210 thermal-magnetic trip unit — fixed overload protection at Ir=100 A and a non-adjustable short-circuit pickup at Ii = 10 × In, so the magnetic trip fires at 1000 A. That fixed ratio means coordination studies need to account for the 10x multiplier; no dial to tweak it down.
What the ratings mean for fit
The 16 kA Icu at 415 V tells you this breaker clears faults up to that level without welding or rupturing — class B switching capacity, so it's rated for full selectivity downstream in a distribution panel. The shunt release (STL) accepts 12–30 V DC or 24 V AC 50/60 Hz, which lets a remote pushbutton or PLC digital output trip it without a separate interposing relay. Two auxiliary switches (HQ) plus a dedicated tripped-signal contact give status feedback for a PLC input or annunciator — one contact for open/closed, one for trip-only indication.
Panel integration notes
Mounts on a standard DIN rail inside an enclosure. The terminal connection style is screw-type, sized for the 100 A rating — torque specs per the manufacturer's installation instructions. The shunt release coil draws from the listed control voltage range; verify the control transformer or power supply can deliver the inrush without dropping below 12 V DC during the trip pulse.
