What the ratings mean for the panel
The Siemens 3VA2220-5MN32-0CL0 is a SENTRON molded case circuit breaker (MCCB) rated 200 A continuously at 40 °C — and that rating holds flat all the way to 70 °C ambient, so no derating curve to calculate for a warm enclosure. The interrupting capacity is 121 kA at 415 V, which puts it in the high-fault tier for industrial distribution; it clears a bolted fault without cascading upstream. The 3-pole design is built for motor protection, with integrated phase failure detection and an undervoltage release (UVR) that drops the load on loss of control voltage — common on pump and conveyor circuits where a no-blackout-on-my-watch philosophy applies.
Integration and mounting
The breaker occupies 105 mm width × 181 mm height × 86 mm depth (4.13 × 7.13 × 3.39 in). That depth is the key dimension for panel clearance — 86 mm means it fits standard 200 mm deep enclosures with room for rear busbars or wiring troughs. The auxiliary switch configuration is factory-fitted: two auxiliary switches plus one trip alarm switch plus one electrical alarm switch, all HQ-rated, plus the undervoltage release. No communication module on this variant; it is a standalone thermal-magnetic MCCB for hardwired control circuits.
