Breaking capacity is 187 kA at 240 V, 121 kA at 415/440 V, and 52.5 kA at 690 V — figures that tell you whether this breaker clears a fault before the upstream gear takes damage. Dimensions are 320 mm high, 210 mm wide, 120 mm deep. That depth is the critical number for gland-plate clearance and door swing — at 120 mm it fits most standard MCC buckets without a sub-panel spacer. Width of 210 mm means it occupies three pole spaces in a typical SENTRON mounting base. If your spec calls for those, you are looking at a different 3VA variant.","metaTitle":"Siemens 3VA1580-5EF32-0DA0 SENTRON MCCB, 800 A, 3-Pole, TM24","metaDescription":"Siemens 3VA1580-5EF32-0DA0 SENTRON molded case circuit breaker. 800 A at 40°C, 3-pole, TM240 thermal-magnetic trip, 187 kA at 240 V.
