The Siemens 3VA2220-7MS32-0AJ0 is a 3-pole SENTRON molded case circuit breaker rated for 200 A continuous current across the full ambient range from 40 °C to 70 °C. The adjustable thermal-magnetic trip unit covers 600 A minimum to 3 000 A maximum, letting you set the instantaneous pickup to match the inrush of a motor or transformer load without nuisance trips. Interrupting capacity hits 330 kA at 240 V and still delivers 242 kA at 415 V and 440 V — enough headroom for high-fault industrial switchboards. The breaker is designed for starter protection, meaning it coordinates with a contactor and overload relay to clear a motor short-circuit while leaving the overload to handle running overcurrent.
