It carries 52.5 kA interrupting capacity at 240 V and 32 kA at 415 V, so it clears high-fault bolted shorts without the breaker welding shut — critical for panel SCCR coordination downstream of a transformer or large motor branch. Above that, it derates linearly: 48 A at 55 °C, 47 A at 60 °C, 46 A at 65 °C, and 45 A at 70 °C. If the panel ambient hits 60 °C, plan for a 47 A continuous load max — the breaker won't nuisance-trip on a 50 A load at that temp, but the TM element will track the thermal curve. ## Interrupting ratings across voltages Interrupting capacity drops as voltage rises: 52.5 kA at 240 V, 32 kA at 415 V, 13.6 kA at 440 V, and 7.5 kA at 690 V. At 690 V, keep the available fault below 7.5 kA or step up to a higher-interrupt frame. Comes with two HQ (high-qualified) auxiliary switches and an undervoltage release (UVR) built in.","metaTitle":"Siemens 3VA1050-2ED36-0DC0 SENTRON MCCB, 50 A, 52.5 kA","metaDescription":"Siemens 3VA1050-2ED36-0DC0 SENTRON MCCB, 3-pole, 50 A rated continuous current, 52.5 kA at 240 V.
