For a starter-protection MCCB, the interrupting curve is what decides whether the breaker clears a bolted fault before the upstream transformer protection needs to coordinate. ## Thermal derating — the real continuous current in a warm cabinet At 55 °C it derates to 96 A, at 60 °C to 94 A, at 65 °C to 92 A, and at 70 °C to 90 A. If your panel sits near a drive stack or in a non-conditioned enclosure, the 55 °C and 60 °C figures are the ones to size against — the breaker does not lose much, but a 100 A load at 60 °C is already 6 A over the 94 A limit. Mounting is via the SENTRON 3VA base plate, which accepts the standard screw-clamp or plug-in lug kits. ## Release and auxiliary configuration The overcurrent release is an ETU310M electronic trip unit — that is the programmable version with LSI curves (long-time, short-time, instantaneous) plus ground-fault capability if the sensor is added.","metaTitle":"Siemens SENTRON 3VA2110-7MS32-0HC0 MCCB, 100 A, 330 kA at 24","metaDescription":"Siemens SENTRON 3VA2110-7MS32-0HC0 molded case circuit breaker, 100 A rated, 330 kA at 240 V interrupting capacity.
