What it is and what the ratings mean
The Siemens SENTRON 3VA2220-5MP32-0AA0 is a 3-pole molded case circuit breaker (MCCB) designed for motor protection, with a rated continuous current of 200 A across the full ambient temperature range from 40 °C to 70 °C — no derating needed up to 70 °C, which simplifies panel sizing in warm enclosures. Its interrupting capacity is 187 kA at 240 V, dropping to 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 5.2 kA at 690 V — so at typical 400 V class distribution voltages it handles high fault currents without cascading upstream, but at 690 V the 5.2 kA limit means it's not for 690 V high-fault panels. Adjustable trip classes include 10A, 10/10E, 20/20E, and 30.
Motor protection and communication
Built-in phase failure detection and a communication function mean this breaker can report trip events and status to a PLC or BMS over a bus — useful for a motor control center where you want remote indication without adding separate auxiliary contacts. Rated insulation voltage is 800 V, and maximum power loss is 46 W — figure that into enclosure heat rise if the panel is densely packed.
Panel fit and mounting
Dimensions are 105 mm wide, 181 mm high, 86 mm deep — a standard MCCB footprint that fits most DIN-rail or panel-mount enclosures without re-drilling.
