For a panel that runs warm — say, 55 °C ambient inside the enclosure — the usable current drops to 98 A. That 2 A difference matters when the breaker is feeding a continuous load near its nameplate; the thermal curve is the real limit, not the 100 A sticker. At 415 V — common in European industrial panels — it still clears 52.5 kA. At 440 V it drops to 32 kA, and at 500 V and 690 V it holds at 7.5 kA. Selectivity studies should use the voltage-specific value, not the headline number. The UVR is wired into the control circuit; when voltage falls below its dropout threshold, it mechanically trips the breaker. That is a standard safety interlock for conveyors, pumps, or any load where unexpected restart after a brownout is hazardous. Dimensions are 130 mm height, 101.6 mm width, and 70 mm depth. The 101.6 mm width (4 inches) is the standard footprint for a 4-pole SENTRON 3VA1 frame; it occupies four 25.4 mm module positions on a DIN rail or mounting plate. No trip indicator is fitted, so a visual check of the handle position is the only local status cue.","metaTitle":"Siemens 3VA1010-3ED42-0DC0 SENTRON MCCB, 100 A, 75.6 kA","metaDescription":"Siemens SENTRON 3VA1010-3ED42-0DC0 molded case circuit breaker, 100 A rated at 40 °C, 75.6 kA breaking at 240 V. 4-pole, line protection, undervoltage release.
