The Siemens 3VA2110-5MN36-0AE0 is a SENTRON molded case circuit breaker (MCCB) designed specifically for motor protection, with a continuous current rating of 100 A that holds flat from 40 °C through 70 °C — no derating needed across that entire ambient range. Breaking capacity hits 121 kA at 415 V and 187 kA at 240 V, giving selectivity headroom for high-fault panels. At 690 V it still clears 3.7 kA, so it handles motor circuits on 400 V class systems without issue. Four HQ auxiliary switches ride onboard for status feedback to the PLC or safety relay.
Panel fit
Dimensions are 105 mm wide by 181 mm tall by 86 mm deep — fits standard MCCB panel cutouts. If you need those, the 3VA2 family has modular accessory slots; this unit ships with the 4 HQ aux switches pre-installed.
