The Siemens 3VA2220-7MN32-0JH0 is a SENTRON molded case circuit breaker (MCCB) built for motor protection — three poles, 200 A continuous at 40 °C, with a 330 kA interrupting rating at 240 V that drops to 5.2 kA at 690 V, so check your system voltage against the curve before committing the BOM line.
Breaking capacity is the headline: 330 kA at 240 V, 242 kA at 415/440 V, 187 kA at 500 V, and 5.2 kA at 690 V — that 690 V figure is the gotcha; if your motor runs at 690 V, this breaker is only good for 5.2 kA fault current, so verify the available fault current at the panel before specifying. Motor protection design means it includes phase failure detection and a thermal-magnetic trip curve tuned for motor starting inrush — the trip delay is adjustable between 4 s and 15 s, which covers most NEMA and IEC motor start profiles. Power loss hits 46 W max at full load — that's heat that stays inside the panel, so factor it into your enclosure thermal budget if you're stacking several breakers in a row.
Auxiliaries and releases
No undervoltage release fitted from the factory, so if your safety circuit requires a UVR for coordinated shutdown, you'll need to add it externally or order a variant that includes it. The basic switch module inside is order code 3VA2220-7MN32-0AA0 — that's the replaceable switching element if the breaker trips on a hard fault and needs a swap without pulling the whole assembly.
