The interrupting ratings are substantial: 330 kA at 240 V, 242 kA at 415 V and 440 V, and 187 kA at 500 V — only at 690 V does it drop to 5.2 kA, which still covers most industrial motor circuits.
What is built into this breaker
The basic switch inside is order code 3VA2220-7MN32-0AA0. No ground-fault monitoring version is included. The voltage trigger is present (the shunt trip activates on a control voltage), but there is no undervoltage release. Maximum power loss is 46 W.
The 200 A continuous rating is flat across the ambient range — no derating curve to calculate. The short-time delay settings (minimum 4 s, maximum 15 s) allow selectivity with downstream devices on coordinated feeder schemes.
