What this MCCB delivers
The Siemens 3VA2220-7MN32-0BL0 is a 3-pole SENTRON molded case circuit breaker (MCCB) rated for 200 A continuously across the full ambient range from 40 °C to 70 °C — no derating needed up to that ceiling, which simplifies panel schedules in warm enclosures. The motor protection design includes phase failure detection and a trip indicator, so a single-phasing event on a compressor or conveyor motor shows up visually on the breaker face.
That means you get status feedback and a UVR without buying separate accessory kits or opening the breaker cover — a time saver on the panel build. The UVR drops the breaker if control voltage falls below its dropout threshold, which is standard for safety circuits that need to guarantee a power-off state when the control supply is lost. The base switch is order code 3VA2220-7MN32-0AA0, so if you ever need a bare breaker without auxiliaries, that is the core variant to cross-reference.
The lifecycle stage for the 3VA2220-7MN32-0BL0 is listed as current — meaning Siemens still actively manufactures and supports this order code as a standard catalog item. No phase-out notice, no last-time-buy window.
Maximum power loss is 46 W, so factor that into the enclosure thermal budget if the panel is sealed or has limited ventilation.
