The Siemens 3VA2220-5MN32-0DC0 is a 3-pole SENTRON molded case circuit breaker (MCCB) rated at 200 A continuously across the full ambient range from 40 °C to 70 °C — no derating needed as the panel warms up. That flat thermal curve is unusual and simplifies panel design: the breaker delivers its full 200 A at 70 °C, not just at the 40 °C reference point. Breaking capacity is 121 kA at 415 V and 440 V, dropping to 75.6 kA at 500 V and 5.2 kA at 690 V. At 240 V it reaches 187 kA. These figures cover most industrial distribution and motor branch circuits; the 415 V rating is the one to check against your transformer or generator fault level. The breaker is designed specifically for motor protection, with phase failure detection built in — it will trip on loss of a phase, preventing single-phasing damage to the motor. An undervoltage release (UVR) is integrated, so the breaker drops out on a sag or loss of control voltage.
Maximum power dissipation is 46 W at rated load. That matters for enclosure thermal calculations: a panel with several of these breakers needs enough ventilation or forced cooling to keep internal ambient below the 70 °C operating limit.
