At 240 V it interrupts 330 kA; at 415 V and 440 V, 242 kA; at 500 V, 187 kA; and at 690 V, 52.5 kA. Those figures are symmetrical RMS — the values a coordination study needs to confirm selectivity with upstream and downstream devices. The overcurrent release is an ETU310M electronic trip unit — that is a microprocessor-based, LSI (long-time, short-time, instantaneous) curve with adjustable pickups and time delays. It gives you the selectivity granularity a thermal-magnetic cannot: you can shape the short-time band to ride through motor inrush and still clear a bolted fault downstream. At 55 °C it derates to 60.48 A; at 60 °C, 59.22 A; at 65 °C, 57.96 A; at 70 °C, 56.7 A. Power loss at full rated current is 75 W, which contributes to the enclosure's internal temperature rise and must be factored into the thermal budget. ## Panel fit and mechanical endurance For a motor-starting application cycling several times a shift, that is a finite but serviceable life; for an infrequently operated feeder, it is effectively permanent.","metaTitle":"Siemens SENTRON 3VA2163-7MS32-0CA0 MCCB, 63 A, 330 kA at 240","metaDescription":"Siemens SENTRON 3VA2163-7MS32-0CA0 molded case circuit breaker, 63 A rated, 330 kA breaking capacity at 240 V, 3-pole, undervoltage release.

Availability and current pricing are confirmed at quote time — submit an RFQ and we will respond with a firm price and delivery estimate. No stock count or lead-time number is published here."},{"question":"When sourcing 3VA2163-7MS32-0CA0, what's the closest functional second-source — 3VA2163-8HM32-0AA0?","answer":"The 3VA2163-8HM32-0AA0 is a peer in the same SENTRON 3VA2 frame size and pole count, but it carries a different overcurrent release and auxiliary configuration. The 3VA2163-7MS32-0CA0 uses an ETU310M electronic trip unit with an undervoltage release, while the 8HM32 variant uses a different release type. They share the same physical footprint (105 mm wide, 181 mm high, 86 mm deep), so a panel designed for one can accept the other without rewiring the bus bars — but the trip curve and auxiliary functions are not identical. Verify the release and auxiliary requirements against your coordination"},{"question":"What is 3VA2163-7MS32-0CA0's listed depth (86 mm) on this component line?","answer":"The depth is 86 mm, measured from the mounting surface to the front of the breaker. That is the projection you need for gland plate clearance and dead-front cover fit."},{"question":"What is 3VA2163-7MS32-0CA0's listed width (105 mm) on this component line?","answer":"The width is 105 mm, which is three standard pole spaces for a 3-pole MCCB on a DIN rail or panel-mount grid."},{"question":"What compliance documentation does this brand provide for 3VA2163-7MS32-0CA0 (RoHS, REACH, UL, IEC)?","answer":"As a current-production Siemens SENTRON MCCB, the part carries CE marking for the European market and UL/CSA listing for North America.
