Its interrupting capacity reaches 187 kA at 240 V AC, 121 kA at 415 V AC, 76 kA at 440 V AC, and 17 kA at 500 V AC — figures that govern selectivity and SCCR coordination in the distribution panel. Above that, the continuous current derates per the datasheet curve: 122 A at 55 °C, 120 A at 60 °C, 117 A at 65 °C, and 114 A at 70 °C. Ambient temperature inside the enclosure governs the usable ampacity — a panel running at 60 °C loses 5 A of headroom versus the 40 °C nameplate. This part carries a current-production lifecycle status. The 3-pole footprint fits standard SENTRON MCCB mounting positions in distribution boards. ## Voltage ratings and release design Maximum power loss is 23 W. ## Environmental limits The storage minimum is the more stringent limit for warehousing and shipping conditions.","metaTitle":"Siemens 3VM1112-5ED32-0AA0 SENTRON MCCB, 125 A, 3-Pole, 187","metaDescription":"Siemens SENTRON 3VM1112-5ED32-0AA0 molded case circuit breaker, 125 A rated, 3-pole, TM210 release.
