The Siemens SENTRON 3VA2220-5MN32-0DB0 is a 3-pole molded case circuit breaker (MCCB) in the motor protection version, rated for a continuous current Iu of 200 A. At 415 V and 440 V it still holds 121 kA, and at 690 V it drops to 5.4 kA, so derate the interrupting rating for higher line voltages. The ETU350M offers adjustable long-time pickup and delay (tr max. 15 s), plus short-time and instantaneous settings, so you can coordinate it with downstream contactors and overload relays.
Dimensions: 105 mm wide, 181 mm tall, 86 mm deep. That 105 mm width (about 4.1 in) is a standard 3-pole MCCB footprint — it fits the usual DIN-rail or panel-mount cutouts in a SENTRON distribution board or a generic enclosure. Ambient operating range from -25 °C to 70 °C, with storage from -40 °C to 80 °C, so it handles unheated warehouses or rooftop enclosures in temperate climates. The 200 A rating holds flat from 40 °C up to 70 °C; no derating needed across that range, which simplifies panel design.
