The Siemens SENTRON 3VA2220-7MN32-0AH0 is a 3-pole molded case circuit breaker (MCCB) rated for 200 A continuous current across its full ambient temperature range from 40 °C to 70 °C — no derating needed up to the enclosure's thermal limit. It is designed specifically for motor protection, with integrated phase failure detection and a trip indicator that shows the breaker has opened on fault, not by manual switching. The 200 A figure governs the motor full-load current it can protect — size your overload relay and conductor accordingly. Breaking capacity is rated 330 kA at 240 V AC, 242 kA at 415 V and 440 V, 187 kA at 500 V, and 5.2 kA at 690 V.
The 86 mm depth means it fits within most 200 mm deep enclosures without interfering with the gland plate or back panel wiring troughs. The trip alarm signals the open-on-fault condition separately from the auxiliary contacts that track the main contact position — useful for remote annunciation and safety interlocks. It is built on the 3VA2220-7MN32-0AA0 basic switch platform, so the internal mechanism and arc chamber are common across the 3VA2 family.
Maximum power loss is 46 W at rated current. The storage limit is for handling and warehousing, not running — the operating limit is what governs the installed environment. Short-time delay (if equipped) is adjustable between 4 s minimum and 15 s maximum — this is the intentional delay before the breaker trips on a short-circuit, used for selective coordination downstream. Verify your coordination study requires this window.
