The Siemens SENTRON 3VA2110-5HL36-0KC0 is a 3-pole molded case circuit breaker (MCCB) rated for 100 A continuous current across the full ambient range from 40 °C to 70 °C — no derating needed up to that ceiling. That flat thermal curve simplifies panel design: you size the bus and lugs for a straight 100 A and don't recalc for summer conditions. Breaking 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.
The 105 mm width matches the typical 3-pole SENTRON 3VA family spacing, so a panel designed for a 3VA2116 or 3VA1110 will accept this unit without re-drilling or busbar rework. The storage minimum matters for unheated warehouses in cold climates — the breaker can sit at -40 °C without damage, but must be at -25 °C or above before energizing.
