At 240 V the interrupting rating hits 187 kA — that is the SCCR the breaker can safely clear without venting or welding contacts, which sets the available fault current the upstream transformer or bus must not exceed. At 415 V it still holds 121 kA; at 690 V it drops to 17 kA, so verify the line-to-line voltage on a 480 V or 600 V system before specifying. ## Thermal derating and deployment context This MCCB holds its full 100 A rating up to 50 °C ambient, then begins a gentle derating curve: 98 A at 55 °C, 96 A at 60 °C, 94 A at 65 °C, and 91 A at 70 °C. That means in a ventilated 40 °C panel it works at nameplate; in a sealed enclosure near a drive or transformer, the actual load must be trimmed by up to 9 % to avoid nuisance thermal tripping over the equipment's service life. The breaker measures 130 mm high, 76.2 mm wide, and 70 mm deep — a 3-pole MCCB footprint that fits standard Siemens SENTRON panel cutouts and busbar systems.","metaTitle":"Siemens 3VA1110-5EF32-0AA0 SENTRON MCCB, 100 A, 3-Pole, TM24","metaDescription":"Siemens SENTRON 3VA1110-5EF32-0AA0 molded case circuit breaker, 100 A at 40 °C, 3-pole, TM240 thermal-magnetic trip, 187 kA at 240 V.
