The Siemens SENTRON 3VA2110-5JQ36-0AA0 is a 3-pole molded case circuit breaker rated for 100 A continuous current from 40 °C to 70 °C. Interrupting capacity is the headline: 187 kA at 240 V, 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 3.7 kA at 690 V. For a 100 A frame those numbers give serious SCCR headroom — it can sit upstream of a distribution board without worrying about cascading faults, as long as the available fault current at its terminals stays under those curves. The adjustable thermal-magnetic trip range runs from 150 A to 1 200 A — that's the magnetic pickup window, not the continuous rating. Set the magnetic threshold to coordinate with downstream branch breakers.
That's a standard SENTRON 3VA fixed-panel mount — bolts onto the backplate, no DIN rail. This variant includes a communication function for a COM module slot, enabling status and trip reporting to a PLC or SCADA. No undervoltage release fitted. Power loss is 10 W maximum — negligible for panel thermal budgeting, but worth noting if you're packing multiple breakers in a sealed enclosure.
