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. That 330 kA at 240 V is high — it'll hold up on large transformer secondaries or busway feeds where fault current is stiff. 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.
Physical fit and panel integration
Dimensions: 181 mm high, 105 mm wide, 86 mm deep. That 105 mm width is standard for a 3-pole frame — it'll drop into a typical MCC bucket or panel-mounted base without surprises. The auxiliary switch block (3 HQ switches) adds about 18 mm to the width; account for that in your wiring gutter.
Environmental range
Operating temperature from -25 °C to 70 °C; storage from -40 °C to 80 °C. Max power loss is 10 W — negligible for most panels, but worth noting if you're packing multiple breakers in a sealed enclosure.
