This is a starter protection version, meaning it's built for motor branch circuit protection where the combination of magnetic and thermal characteristics is tuned for starting inrush rather than straight feeder duty. The interrupting capacity is substantial: 330 kA at 240 V, 242 kA at 415 V and 440 V, 187 kA at 500 V, and still 52.5 kA at 690 V. That kind of headroom tells me the upstream transformer or bus can dump serious fault energy into this panel, and the breaker won't vent or weld. ## Release and accessory fit The overcurrent release is an ETU310M — an electronic trip unit with LSI curves (long-time, short-time, instantaneous), adjustable for coordination downstream. The basic switch supplied inside is 3VA2163-7MS36-0AA0. If your BOM calls for undervoltage release or a ground-fault module, this variant isn't it — you'd need a different suffix. Maximum power loss is 75 W, which matters for enclosure heat rise calculations — if you're packing several of these in a sealed cabinet, factor that dissipation into the thermal budget.","metaTitle":"Siemens SENTRON 3VA2163-7MS36-0KA0 MCCB, 63 A, 330 kA at 240","metaDescription":"Siemens SENTRON 3VA2163-7MS36-0KA0 molded case circuit breaker, 63 A rated, 3-pole, starter protection version with ETU310M release.
