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. Designed specifically for motor protection, it carries a 121 kA breaking capacity at 415 V and 187 kA at 240 V, meaning it can safely interrupt high fault currents on a motor branch circuit without cascading upstream.
Breaking capacity and selectivity
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. The auxiliary switch configuration is one auxiliary switch plus one trip alarm switch (HQ), and a shunt trip release (STL) is built in for remote tripping via a control signal. No undervoltage release or ground-fault monitoring is fitted on this variant.
Panel fit and environmental limits
Dimensions are 105 mm wide, 181 mm tall, and 86 mm deep — the 86 mm depth is the critical clearance behind the panel door for wiring and bus connections. Operating temperature range is -25 °C to 70 °C; storage range is -40 °C to 80 °C. Maximum power loss is 46 W, which matters for enclosure heat rise calculations when several breakers are ganged together.
