The interrupting rating hits 220 kA at 240 V, 154 kA at 415 V, and 121 kA at 440 V — enough for high-fault industrial services.
The 3VA1140-6EE32-0AA0 occupies a 76.2 mm wide, 130 mm tall, 70 mm deep footprint — standard for a 3-pole SENTRON 3VA1 frame. The TM220 release is fixed; no trip indicator or undervoltage release on this variant.
Rated 40 A from 40 °C up to 50 °C; at 55 °C it drops to 39 A, at 65 °C to 38 A, and at 70 °C to 37 A. That's a shallow derating curve — good for warm panels. Maximum power loss is 10.8 W, so heat buildup in a dense cabinet is manageable.
