Rated breaking capacity reaches 52.5 kA at 240 V, 32 kA at 415 V, 13.6 kA at 440 V, and 7.5 kA at both 500 V and 690 V. Maximum power loss is 14.6 W — relevant for enclosure thermal calculations when grouping multiple breakers. Dimensions are 130 mm height, 76.2 mm width, 70 mm depth — a standard 3-pole MCCB footprint that fits most DIN-rail or screw-mount panel layouts. The shunt trip (STL) adds a small module on the side; verify clearance if retrofitting into a tight gland plate.","metaTitle":"Siemens 3VA1050-2ED32-0KA0 SENTRON MCCB, 50 A, 52.5 kA at 24","metaDescription":"Siemens SENTRON 3VA1050-2ED32-0KA0 molded case circuit breaker, 3-pole, 50 A, TM210 release, shunt trip, 52.5 kA at 240 V.

It will drop into a panel specified for the 3VA1050 without rewiring, but the continuous rating must match the load — the 50 A 3VA1050 cannot be replaced by a 10 A breaker."},{"question":"What is the depth of 3VA1050-2ED32-0KA0?","answer":"The depth is 70 mm (2.76 in)."},{"question":"What is the width of 3VA1050-2ED32-0KA0?","answer":"The width is 76.2 mm (3 in)."},{"question":"Will 3VA1050-2ED32-0KA0 drop into a panel that was specified around 3VA1010-2ED32-0AD0 without rewiring?","answer":"Yes — both share the same 3-pole footprint, same TM210 release, and same shunt trip module, so the physical fit and terminal layout are identical. The only difference is the continuous current rating (50 A vs 10 A), so the upstream protection and conductor sizing must be verified."},{"question":"What compliance documentation does Siemens provide for 3VA1050-2ED32-0KA0?","answer":"Siemens SENTRON MCCBs typically carry UL 489, CSA C22.2 No. 5, IEC 60947-2, CE, and RoHS/REACH declarations.
