The Siemens 3VA2220-5MN32-0BC0 is a SENTRON molded case circuit breaker (MCCB) rated for 200 A continuous at up to 70 °C ambient, with no derating across the full temperature range.
Interrupting capacity and selectivity
Interrupting capacity is voltage-dependent: 187 kA at 240 V, 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 5.2 kA at 690 V.
Integration notes
Dimensions are 181 mm high, 105 mm wide, and 86 mm deep — a standard SENTRON 3VA2 frame size that mounts on a DIN rail or panel-mount adapter. The unit includes two auxiliary switches (HQ design) and an undervoltage release. Power loss is 46 W maximum at rated current, so account for heat dissipation in the enclosure. Operating temperature range is -25 °C to +70 °C; storage range is -40 °C to +80 °C.
