What this 200 A MCCB is and what it does
The Siemens 3VA2220-5MQ32-0AB0 is a SENTRON molded case circuit breaker (MCCB) rated 200 A continuous at 40 °C across all three poles, with an adjustable thermal-magnetic trip unit covering 40 A to 200 A full-scale. That means you set the trip threshold to match the load — pump, conveyor, compressor, feeder — without swapping the breaker body. The 3-pole design handles three-phase circuits up to 690 V, with interrupting capacity of 187 kA at 240 V and 121 kA at 415 V, so it safely clears high-fault scenarios common in industrial distribution. Phase failure detection is built in, and the auxiliary switch pack (2 auxiliary switches HP) provides remote status feedback for PLC or SCADA monitoring. Communication function is present — this variant supports integration into higher-level monitoring without an add-on module.
Where it fits in the panel
The breaker measures 105 mm wide, 181 mm tall, and 86 mm deep — a standard MCCB footprint for 200 A class. It mounts directly to a DIN rail or panel plate. The 86 mm depth means it clears most standard enclosure depths without a deep-can modification. Power loss is 46 W maximum at rated load, so factor that into enclosure thermal calculations — especially in a sealed cabinet with other heat sources.
Breaking capacity across voltages
Interrupting ratings step down 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. The 690 V figure is low enough that you need to verify available fault current at that voltage — typical for 690 V drives or mining gear — before committing the BOM line.
