Frame dimensions are 130 mm high, 76.2 mm wide, 70 mm deep (-), so it fits standard 3-pole MCCB panel cutouts. ## Thermal derating and ambient — the real continuous current This breaker holds its full 63 A rating through 50 °C (-). At 55 °C it derates to 62 A, at 65 °C to 60 A, and at 70 °C to 58 A (-). That's a shallow derating curve — useful for panels with elevated internal ambient near other heat sources. The TM240 release is fixed thermal-magnetic; no electronic adjustment or communication function. ## Breaking capacity across voltages — selectivity planning Interrupting rating drops with system voltage: 187 kA at 240 V, 121 kA at 415 V, 75.6 kA at 440 V, and 17 kA at both 500 V and 690 V (-). At 70 mm deep and 76.2 mm wide, this breaker occupies one standard 3-pole MCCB slot. The 17.3 W maximum power loss is moderate; account for it in enclosed panel thermal calculations, especially when grouping multiple breakers.","metaTitle":"Siemens 3VA1163-5EF32-0AA0 SENTRON MCCB, 63 A, 3-Pole, TM240","metaDescription":"Siemens SENTRON 3VA1163-5EF32-0AA0 molded case circuit breaker, 63 A at 40 °C, 3-pole, TM240 thermal-magnetic release, 187 kA at 240 V.
