That voltage-dependent curve is typical of current-limiting MCCBs — the arc energy scales with voltage, so the interrupting rating drops. For a 480 V panel (common in North America), the 187 kA figure still covers most utility transformer secondary faults. At 690 V, the 52.5 kA rating suits industrial loads like large motors or VFD input feeders where fault current is lower. ## Thermal derating and ambient limits Above that, it derates: 60.48 A at 55 °C, 59.22 A at 60 °C, 57.96 A at 65 °C, and 56.7 A at 70 °C. ## Starter protection version This is the starter protection variant, meaning it's designed to coordinate with a contactor for motor starting duty. It includes a voltage trigger and the ETU310M release, but lacks an undervoltage release, auxiliary contacts, phase failure detection, ground fault monitoring, or communication functions. The mechanical endurance is 20,000 cycles — adequate for motor starting applications where the breaker sees infrequent switching (the contactor handles daily starts). The depth of 86 mm includes the case body; allow extra for wiring and the shunt trip coil protrusion. Mounting is via screw-clamp to a backplate or DIN rail adapter (not included).","metaTitle":"Siemens 3VA2163-7MS32-0HA0 SENTRON MCCB, 63 A, 330 kA at 240","metaDescription":"Siemens 3VA2163-7MS32-0HA0 SENTRON molded case circuit breaker, 63 A rated, 330 kA breaking at 240 V.
