Breaking capacity is the headline: 330 kA at 240 V, 242 kA at 415 V and 440 V, 187 kA at 500 V, and 52.5 kA at 690 V. The shunt trip (STL) allows remote emergency-off or interlock tripping from a PLC or E-stop circuit. ## Thermal derating — the real-world current Above that, derate linearly: 96 A at 55 °C, 94 A at 60 °C, 92 A at 65 °C, 90 A at 70 °C. Maximum power loss is 75 W. That's the heat the breaker dumps into the enclosure at full rated current — factor it into your cabinet thermal budget, especially in a dense MCC lineup. ## Auxiliary contacts and trip indication Comes with 2 auxiliary switches (NO/NC for status feedback) plus 1 dedicated trip alarm switch (HQ) that changes state only on a fault trip — not on manual open/close. That HQ contact is the one to wire to your PLC alarm input for a true trip signal, not just a breaker-off indication. Voltage trigger and trip indicator are present. The base switch (the breaker mechanism without the shunt trip and auxiliaries) is order code 3VA2110-7MS32-0AA0. The integrated auxiliary trip module is 3VA9688-0BL32. If you already have the base breaker available via RFQ confirmation and need to add the shunt trip and aux contacts separately, those are the sub-assembly order codes to source.","metaTitle":"Siemens 3VA2110-7MS32-0JH0 SENTRON MCCB, 100 A, 330 kA at 24","metaDescription":"Siemens SENTRON 3VA2110-7MS32-0JH0 molded case circuit breaker, 100 A rated, 330 kA breaking at 240 V.
