It is designed specifically for starter protection, meaning it is built to coordinate with motor contactors and overload relays in motor control centers (MCCs) and individual motor starter buckets. The 3VA2163 frame carries a maximum adjustable trip setting of 945 A and a minimum of 189 A, giving you a wide band to match motor full-load amps without swapping the breaker body. ## Breaking capacity — the so-what for fault duty At 415 V and 440 V it still holds 242 kA, and at 500 V it delivers 187 kA. The sharp drop to 3.7 kA at 690 V tells you this frame is not intended for 690 V motor circuits; the 690 V figure is a residual rating for lightly loaded feeder duty. For a 480 V or 400 V motor starter lineup, the 242 kA at 415 V gives ample SCCR headroom to avoid a cascading failure upstream. ## Integration notes for panel builders Power loss is 4 W maximum, negligible for thermal budget in a sealed enclosure.","metaTitle":"3VA2163-7MS36-0AC0 SENTRON MCCB, 63 A, 3-pole, starter prote","metaDescription":"Siemens SENTRON 3VA2163-7MS36-0AC0 molded case circuit breaker, 63 A continuous, 3-pole, 330 kA at 240 V.
