That means a panel designed for 63 A at 40 °C still holds the same rating if the enclosure runs hotter. The interrupting capacity of 187 kA at 240 V and 121 kA at 415 V gives substantial SCCR headroom for most industrial distribution panels; the drop to 3 kA at 690 V tells you this is a 480 V class breaker, not a 690 V one. The auxiliary switch configuration includes two auxiliary switches, one trip alarm switch, and one electrical alarm switch (HQ type), giving four discrete signals for PLC or SCADA inputs. ## Panel integration and physical fit The undervoltage release and communication module add some depth on the side, but the overall envelope stays within the SENTRON 3VA family's typical panel cutout.","metaTitle":"Siemens 3VA2063-5JQ32-0BL0 SENTRON MCCB, 63 A, 3-Pole, 187 k","metaDescription":"Siemens SENTRON 3VA2063-5JQ32-0BL0 molded case circuit breaker, 63 A, 3-pole, 187 kA at 240 V.
