The SENTRON 3VA2163-5JQ32-0BA0 is a 3-pole molded case circuit breaker (MCCB) rated for line protection at 63 A continuous. Its interrupting capacity hits 187 kA at 240 V and 121 kA at 415 V — enough for high-fault utility feeds or transformer secondaries where a standard MCB would weld shut. The 63 A rating holds flat from 40 °C through 70 °C, so no derating curve to chase in a warm enclosure.
Sizing and selectivity
The adjustable thermal-magnetic trip range spans 95 A to 756 A, though the frame's continuous rating is 63 A. That means the trip unit is set for a lower pickup than the breaker's physical capacity — useful when you need a 63 A feeder but want the mechanical headroom of a larger frame. The undervoltage release drops the breaker on loss of control voltage, standard for emergency-stop or undervoltage protection schemes. No trip indicator on this variant, so plan on a separate auxiliary contact if you need remote status.
Mounting and integration
Dimensions are 105 mm wide, 181 mm tall, 86 mm deep — fits standard MCCB panel cutouts in SENTRON distribution boards. The 3-pole block occupies three modular units. Spring-cage or screw terminals accept copper conductors up to the rated cross-section; verify lug kit compatibility with your busbar layout. Communication function is present, so it can integrate with SENTRON power monitoring systems via the optional COM module.
Lifecycle and sourcing
Listed as current production — no EOL notice, no successor announced. This is the active catalog number for new builds and BOM replacements. Sourced to order against an RFQ through independent distribution; availability and pricing confirmed at quote time.
