Siemens 3VA1110-5ED32-0AH0 SENTRON MCCB, 100A, 3-Pole, 187kA

The 3VA1110-5ED32-0AH0 is a Siemens SENTRON 3-pole MCCB rated for line-protection duty — meaning it sits at the feeder or main branch in a distribution panel, not on a motor or a specific load. Its continuous current holds 100 A from 40 °C through 50 °C without derating, then drops to 98 A at 55 °C and 91 A at 70 °C (the operating maximum). That thermal curve matters: if your panel ambient runs at 55 °C, you lose 2 A off the nameplate; at 65 °C you lose 6 A. The TM210 thermal-magnetic release gives a fixed thermal pickup plus magnetic trip for short-circuit events — no electronic adjustment, so it's a set-and-forget part for standard distribution. At 240 V it clears 187 kA — that's the highest single rating on the ledger and covers most industrial services. At 415 V it still handles 121 kA, at 440 V it's 75.6 kA, and at 500 V or 690 V it drops to 17 kA. If your fault current at 480 V is above 17 kA, this breaker is not the right pick — you need a higher-rated frame.
