MCCB for Motor and Starter Protection
The Siemens SENTRON 3VA2163-7MS36-0JC0 is a 3-pole molded case circuit breaker (MCCB) rated at 63 A continuous current across the full ambient range from 40 °C to 70 °C, meaning no derating is needed for elevated panel temperatures up to that limit. The design is explicitly for starter protection, which means it's tuned for motor-starting inrush and coordinated with contactor/overload combinations in a motor control center.
Integrated Shunt Trip and Auxiliary Switching
The auxiliary switches share the same compact frame, so no external relay interface is needed for remote indication. The shunt trip allows emergency-stop circuits or supervisory systems to open the breaker without a manual action.
The 3-pole footprint matches the typical MCC bucket layout for motor feeder groups.
