At 415 V it still interrupts 121 kA, and at 690 V it holds 17 kA, so it handles industrial 400 V distribution panels and 690 V drives as well. The thermal-magnetic trip curve is factory set for line protection (cable/feeder), not motor overload. If you need a motor-protective characteristic, this is the wrong variant — look for the 3VA1 with a different design suffix. ## Integration and footprint Dimensions: 130 mm height, 76.2 mm width (3 inches), 70 mm depth. The 3-pole width is standard for a 63 A frame — fits a 3-module slot on a DIN-rail assembly. No separate auxiliary switch block needed for basic open/closed indication. No undervoltage release is fitted (that would be a different order code). ## Thermal derating — what the 63 A rating actually means At 55 °C it drops to 62 A, at 60 °C to 61 A, and at 70 °C to 58 A.","metaTitle":"Siemens 3VA1163-5EE32-0HC0 SENTRON MCCB, 63 A, 187 kA at 240","metaDescription":"Siemens SENTRON 3VA1163-5EE32-0HC0 molded case circuit breaker, 63 A rated at 40 °C, 187 kA breaking capacity at 240 V. 3-pole, shunt trip release.
