The Siemens SENTRON 3VA2110-5HL36-0CH0 is a 3-pole molded case circuit breaker rated for 100 A continuous current at 40 °C, with an adjustable thermal-magnetic trip unit covering 150 A to 1 200 A. That trip range means you set the instantaneous pickup to match the downstream load's inrush — useful for motor or transformer feeders where you want to avoid nuisance trips on startup while still clearing a hard fault. Breaking capacity runs 187 kA at 240 V, 121 kA at 415/440 V, 75.6 kA at 500 V, and 3.7 kA at 690 V.
That lets a PLC distinguish a breaker trip from a normal open command.
Temperature derating — what the 100 A rating actually means
That is unusual for a molded case breaker — most need a derate factor above 40 °C. If your panel internal ambient stays under 70 °C, you can load this breaker to its full 100 A nameplate.
