That curve tells you where it's comfortable — it's built for 400 V class distribution where the SCCR at the panelboard lands around 65–100 kA. At 690 V the 17 kA limit means it's not your primary for a 690 V motor center unless the available fault is low. ## Thermal derating — what the 63 A actually means at panel ambient Above that it starts to step down: 60.48 A at 55 °C, 59.22 A at 60 °C, 57.96 A at 65 °C, and 56.7 A at 70 °C. ## Undervoltage release and auxiliary release options That means it will trip if control voltage drops, which is useful for safety circuits that need to drop the main breaker on a power-loss condition. No auxiliary contact version is included (order separately if you need status feedback), and there is no communication function or ground fault monitoring on this build. Dimensions: 130 mm height, 76.2 mm width (3-pole), 70 mm depth. Mounts with screw terminals; no plug-in base on this variant.","metaTitle":"Siemens 3VA1163-5EE32-0BA0 SENTRON MCCB, 63 A, 187 kA at 240","metaDescription":"Siemens SENTRON 3VA1163-5EE32-0BA0 molded case circuit breaker, 63 A rated continuous current, 187 kA breaking capacity at 240 V.
