The Siemens 3VA2220-7MS32-0BC0 is a 3-pole SENTRON molded case circuit breaker (MCCB) rated for 200 A continuously at 40 °C through 70 °C — no derating needed across that span. The 330 kA breaking capacity at 240 V AC gives you serious fault-current headroom; at 415 V / 440 V it still interrupts 242 kA, and at 500 V it clears 187 kA. That SCCR lets you place this breaker upstream of a motor starter without worrying about series-rated limitations in most industrial panels.
Built-in accessories for motor control circuits
The UVR ensures the breaker trips on loss of control voltage — standard practice for motor safety circuits where you want the starter to drop out on a control-power failure. No communication module or ground-fault monitoring is fitted on this version, so if you need those, you're looking at a different suffix.
Panel fit and mechanical integration
That's a 3-pole frame that mounts via the standard MCCB footprint — no DIN-rail clip on this class; it bolts or screws to the backplate. Maximum power dissipation is 46 W, so account for that heat in a sealed cabinet.
