The Siemens SENTRON 3VA2110-7MN32-0AD0 is a 3-pole molded case circuit breaker (MCCB) rated for 100 A continuous at 40 °C through 70 °C — no derating needed across that band, which simplifies panel design in warm enclosures. It's built for motor protection, with integrated phase failure detection and a 3-auxiliary-switch HQ block for status feedback back to the PLC.
Interrupting ratings and selectivity
This MCCB carries a 330 kA interrupting capacity at 240 V, 242 kA at 415/440 V, 187 kA at 500 V, and 3.7 kA at 690 V. The sharp drop at 690 V (3.7 kA) means you need to check coordination if this breaker sits on a 690 V system; it's not a universal high-voltage interrupt device.
The auxiliary switch block (3 HQ switches) adds about 18 mm to the width; account for that in your wiring gutter.
