The thermal curve holds a full 100 A from 40 °C through 50 °C, then steps down: 98 A at 55 °C, 96 A at 60 °C, 94 A at 65 °C, and 91 A at 70 °C. The basic switch core is order code 3VA11105EE320AA0, so if you need a replacement internal mechanism that's the sub-assembly to reference. Dimensions are 130 mm high, 76.2 mm wide, 70 mm deep — a standard 3-pole MCCB footprint that drops into SENTRON distribution boards and most DIN-rail or screw-mount enclosures without re-drilling.","metaTitle":"Siemens 3VA1110-5EE32-0BC0 SENTRON MCCB, 100 A, 3-Pole, 187","metaDescription":"Siemens SENTRON 3VA1110-5EE32-0BC0 molded case circuit breaker, 100 A rated, 3-pole, 187 kA breaking capacity at 240 VAC.
