The 121 kA interrupting rating at 240 V covers high-fault utility feeds; at 415 V it still clears 75.6 kA, and at 690 V it manages 11.9 kA. The 76.2 mm width (3 in) and 70 mm depth (2.76 in) fit a standard MCCB slot on a DIN rail or panel-mount base. Height is 130 mm (5.12 in). The undervoltage release (UVR) is factory-fitted — verify coil voltage against the control circuit before wiring; the release trips the breaker on loss of control power, which is typical for emergency-stop chains or undervoltage protection schemes. Compared to the 3VA1110-5EF32-0LA0 (a 100 A frame with electronic trip), this 3VA1163-4EF32-0BA0 uses a TM240 thermal-magnetic overcurrent release and tops out at 63 A. The 3VA1110-5EF32-0LA0 offers higher ampacity and adjustable trip settings but lacks the factory UVR this unit carries. Panel cutout dimensions are similar across the 3VA1 frame family, so a swap between the two requires checking the lug kit and trip curve, not the mounting footprint.","metaTitle":"Siemens 3VA1163-4EF32-0BA0 SENTRON MCCB, 63A, 3-Pole, 121kA","metaDescription":"Siemens SENTRON 3VA1163-4EF32-0BA0 molded case circuit breaker, 63A rated at 40°C, 3-pole, 121kA breaking at 240V.
