The 8 kA at 415 V is adequate for most European-style 400 V panelboards feeding motor control centers or lighting distribution. At 60 °C and above it steps down to 19 A. That's a clean, predictable curve: you can load it at 20 A in most standard enclosures without worrying about nuisance tripping from ambient heat. At 25.4 mm wide (1 inch exactly), this single-pole MCCB fits a standard 25 mm DIN-rail slot — one module width. Depth is 70 mm, height 130 mm. That's compact enough for a 12-way distribution board where every millimeter of rail space counts. The TM210 release is thermal-magnetic, so it gives you inverse-time overload protection plus instantaneous short-circuit trip.","metaTitle":"Siemens 3VM1120-3ED16-0AA2 SENTRON MCCB, 1-pole, 20 A, 53 kA","metaDescription":"Siemens 3VM1120-3ED16-0AA2 SENTRON molded case circuit breaker, 1-pole, 20 A rated, 53 kA at 240 V AC, 8 kA at 415 V AC.
