At 55 °C it still delivers 60.48 A, at 60 °C it delivers 59.22 A, at 65 °C it delivers 57.96 A, and at 70 °C it delivers 56.7 A, so you get full 63 A capacity in most standard enclosures without oversizing the frame. Breaking capacity is the headline here: 121 kA at 240 V, 75.6 kA at 415 V, 52.5 kA at 440 V, and 11.9 kA at 690 V. The TM210 thermal-magnetic release is a fixed-trip curve, not electronic, so there is no adjustment dial; the trip curve is set at the factory. No ground fault monitoring, no phase failure detection, no communication function — this is a straightforward line-protection MCCB, not a smart breaker. The 4-pole width (101.6 mm) is roughly 4 modules of 25.4 mm each.","metaTitle":"Siemens 3VA1063-4ED42-0CC0 SENTRON MCCB, 63 A, 4-Pole, 121 k","metaDescription":"Siemens 3VA1063-4ED42-0CC0 SENTRON molded case circuit breaker, 63 A rated continuous current, 4 poles, 121 kA breaking capacity at 240 V.
