That means in a warm panel you still get nearly full rated current; no need to oversize for ambient headroom unless you're above 70 °C. The interrupting ratings tell the real story: 75.6 kA at 240 V, 52.5 kA at 415 V, 32 kA at 440 V, and 7.5 kA at both 500 V and 690 V. At 690 V the 7.5 kA is still adequate for most motor branch circuits, but verify against your transformer's through-fault capability. It's line-protection design, meaning it's sized to protect cable and bus rather than a specific motor or transformer. The 3VA1063-3ED36-0JA0 measures 130 mm high, 76.2 mm wide, and 70 mm deep — a 3-pole frame that fits standard MCCB panel cutouts. The shunt trip is wired separately — it's not an undervoltage release, so it requires a sustained control voltage to hold the breaker closed.","metaTitle":"Siemens 3VA1063-3ED36-0JA0 SENTRON MCCB, 63 A, 75.6 kA at 24","metaDescription":"Siemens SENTRON 3VA1063-3ED36-0JA0 molded case circuit breaker, 63 A rated at 40 °C, 75.6 kA breaking at 240 V.
