Breaking capacity is 121 kA at 240 V AC, 75.6 kA at 415 V, and 52.5 kA at 440 V — figures that cover most low-voltage fault scenarios in industrial and commercial mains. The TM210 thermal-magnetic overcurrent release handles the overload and short-circuit protection curves. Dimensions are 130 mm high, 101.6 mm wide, and 70 mm deep — a standard 4-pole MCCB footprint that fits most Siemens 3VA panelboards and retrofit cutouts. ## Current production — sourcing and lifecycle Maximum power loss is 19.8 W — a figure to factor into enclosure thermal calculations when grouping several breakers in a panel. The breaker is rated for use in unconditioned enclosures within those limits. With a 63 A frame and high interrupting ratings (121 kA at 240 V, 75.6 kA at 415 V), this MCCB is suited for main or feeder positions where fault current is substantial. The TM210 release provides thermal-magnetic protection — no electronic adjustment, but the fixed curve is well-characterized for coordination with downstream 3VA or 5SY series breakers.","metaTitle":"Siemens 3VA1063-4ED42-0DA0 SENTRON MCCB, 63A, 4-Pole, 121kA","metaDescription":"Siemens SENTRON 3VA1063-4ED42-0DA0 molded case circuit breaker, 63A rated, 4-pole, 121kA breaking capacity at 240V AC.
