This breaker's interrupting capacity drops as system voltage rises: 187 kA at 240 V, 121 kA at 415 V, 76 kA at 440 V, and 17 kA at 500 V. That's well above typical 50-65 kA panelboard ratings, so it works as a main breaker feeding downstream branch protection without coordination concerns at the service entrance. ## Thermal derating — don't ignore the ambient curve At 55 °C it's 78 A, at 60 °C it's 77 A, at 65 °C it's 75 A, and at 70 °C it's 74 A. That's a 7.5% drop from 40 °C to 70 °C — tighter than many MCCBs, which can lose 15-20%. The 3VM series uses a compensated bimetal; you don't need to oversize the frame for a warm enclosure. ## Panel fit and environment Mounts on a DIN rail or panel-mount plate — the 101.6 mm width (4 inches) and 130 mm height fit standard SENTRON 3VM cutouts.","metaTitle":"Siemens 3VM1180-5GE42-0AA0 SENTRON MCCB, 4P, 80A, 187kA@240V","metaDescription":"Siemens SENTRON 3VM1180-5GE42-0AA0 molded case circuit breaker, 4-pole, 80A rated at 40°C, TM220 release, 187kA interrupting at 240V.
