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. Communication function is present — this variant supports integration into higher-level monitoring without an add-on module.
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.
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.
