That 800 A instantaneous threshold means it clears hard faults fast, but won't nuisance-trip on moderate inrush from a transformer or capacitor bank. ## Breaking capacity — the real-world fit At 240 V it breaks 121 kA — that's a very high interrupting rating for a single-pole MCCB, suitable for large fault-current panels downstream of a big transformer. The 500 V rated insulation voltage (Ui) and 250 V max DC operational voltage (Ue) tell you this pole is designed for AC line work; if you need DC branch protection, check the 3VA DC manual for the derating curve. ## Thermal derating — don't ignore it The 80 A rating holds flat from 40 °C to 50 °C, then starts to taper: 78 A at 55 °C, 77 A at 60 °C, 75 A at 65 °C, 74 A at 70 °C. ## Mechanical fit and panel integration Dimensions: 70 mm deep, 25.4 mm wide (1 inch), 130 mm tall (5.1 inches). At 25.4 mm per pole, a 3-pole version would take about 76.2 mm of DIN rail — standard 35 mm DIN rail mount. No communication function built in; this is a standalone breaker, not a smart metering device.","metaTitle":"Siemens 3VA1180-5ED12-0AA0 SENTRON MCCB, 1-pole 80 A, 240 V","metaDescription":"Siemens 3VA1180-5ED12-0AA0 SENTRON 1-pole MCCB, 80 A rated at 40 °C, 121 kA at 240 V.
