The Siemens 3VA2110-5MN32-0JC0 is a SENTRON molded case circuit breaker (MCCB) designed specifically for motor protection, with a 3-pole configuration and a full-load current rating of 100 A that holds steady across the entire 40 °C to 70 °C ambient range — no derating needed in a warm panel.
Interrupting capacity and selectivity
At 240 V this breaker clears 187 kA of fault current, dropping to 121 kA at 415 V and 440 V, then 75.6 kA at 500 V, and 3.7 kA at 690 V.
Panel integration
The 3VA2 frame is a common Siemens SENTRON footprint; if you're swapping into an existing panel that was specified around a 3VA2116 frame, check the lug spacing and bus connection points — the frame height and width are the same, but the 100 A versus 160 A rating changes the line-side lug kit.
