The Siemens SENTRON 3VA2220-5MN32-0CA0 is a 3-pole molded case circuit breaker (MCCB) rated 200 A continuously at ambient temperatures from 40 °C up to 70 °C — no derating needed across that range. It is designed specifically for motor protection, meaning the trip curve and thermal memory are tuned for the inrush and overload profile of induction motors rather than resistive or general-distribution loads.
This breaker carries a 187 kA interrupting rating at 240 V AC, dropping to 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 5.2 kA at 690 V.
Motor protection features and auxiliary releases
The breaker includes phase-failure detection, which trips the breaker if one phase drops out — a common cause of single-phasing motor damage. The basic switch variant is 3VA2220-5MN32-0AA0, meaning the internal switching mechanism is shared with that base model. No auxiliary switch is installed, so if you need a remote status contact, plan to add one.
Depth of 86 mm means it clears most 200 mm-deep enclosures, but check gland-plate clearance if the breaker is mounted near the back wall.
