The interrupting ratings tell you where it can clear a fault: 187 kA at 240 V AC, 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 3 kA at 690 V. The 3 kA at 690 V is a reminder that at higher voltages the arc energy is harder to extinguish, so the breaker is really sized for 240–500 V distribution. That means no derating curve to calculate for a warm panel — the breaker holds its full rating at 70 °C. Maximum power loss is 5.4 W, which is modest for a 63 A frame; it won't drive up the enclosure's internal temperature noticeably. ## Built-in communication and auxiliary switching The breaker includes a communication function — that means it can report status or accept remote commands via the SENTRON communication modules (not included in this base order code). The three HQ auxiliary switches provide remote indication of the main contact position.","metaTitle":"SENTRON 3VA2063-5JQ32-0AD0 MCCB, 63 A, 3-pole, 187 kA at 240","metaDescription":"SENTRON 3VA2063-5JQ32-0AD0 molded case circuit breaker, 63 A, 3-pole, 187 kA at 240 V.
