Its interrupting capacity hits 187 kA at 240 V, tapering to 121 kA at 415 V and 75.6 kA at 440 V — enough headroom to clear high-fault conditions without cascading upstream. Current rating holds flat at 125 A from 40 °C through 50 °C, then derates gradually to 114 A at 70 °C. The breaker measures 70 mm deep by 76.2 mm wide by 130 mm tall — a standard 3-pole MCCB footprint that drops into a SENTRON distribution panel or standalone enclosure without re-drilling the mounting plate.","metaTitle":"Siemens 3VA1112-5ED32-0AG0 SENTRON MCCB, 3-Pole, 125 A, 187","metaDescription":"Siemens SENTRON 3VA1112-5ED32-0AG0 molded case circuit breaker, 3-pole, 125 A at 40 °C, 187 kA interrupting at 240 V.
