Its job is to clear a fault before it propagates upstream, and the interrupting ratings back that: 220 kA at 240 V, 154 kA at 415 V, 75.6 kA at 440 V, 30 kA at 500 V, 17 kA at 690 V. Rated continuous current is 200 A at 40 °C, and it holds that figure through 50 °C — only starts derating at 55 °C (194 A), dropping to 176 A at 70 °C. The TM220 designation on the overcurrent release means it's a thermal-magnetic trip unit fixed at 200 A — no interchangeable rating plugs, no electronic adjustment. For a sourcing decision, that locks the breaker to a 200 A feeder; if the BOM calls for a different amp rating, this isn't the variant.
Dimensions are 105 mm wide, 158 mm high, 70 mm deep — a standard 3-pole MCCB footprint for a 200 A frame. No undervoltage release, no shunt trip, no communication function — this is a straight electromechanical breaker with a manual handle and a trip indicator (which is absent on this variant). If the spec calls for remote tripping or status feedback, you'd need a different 3VA option with the accessory slot populated.
