The Siemens SENTRON 3VA2220-5MN32-0JF0 is a 3-pole molded case circuit breaker (MCCB) rated for a continuous 200 A across the full 40 °C to 70 °C ambient range — no derating needed as the panel warms up.
The interrupting ratings step down predictably with voltage: 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. For a 480 V motor control center, the 121 kA at 440 V figure gives the SCCR headroom to coordinate with downstream starters and upstream main breakers — a key consideration for the site electrical engineer planning selectivity.
Motor protection features and auxiliary hardware
This MCCB includes phase failure detection and a trip indicator with voltage trigger — the breaker signals a trip condition without needing a separate monitoring relay.
Maximum power loss is 46 W, which matters for enclosure heat rise calculations when several breakers are ganged together.
