The 3VA2220-5MQ32-0AA0: This is a Siemens SENTRON 3VA2 molded case circuit breaker, three-pole, rated 200 A continuous at 40 °C through 70 °C — meaning it holds full current across the whole panel ambient range, no derating curve to chase. It's built for motor protection, with an ETU860M electronic trip unit that gives you adjustable trip class (10A, 10/10E, 20/20E, 30), phase failure detection, ground-fault monitoring via summation current, and a communication function for remote status.
The interrupting ratings are the real story here. At 240 V it clears 187 kA — that's a massive fault level, typical for a main or large feeder breaker in an industrial distribution panel. At 500 V it drops to 75.6 kA, and at 690 V it's 5.2 kA. The takeaway: this breaker is sized for high-fault upstream positions at 240–440 V, not for a 690 V motor branch. If your system is 480/277 V, the 75.6 kA at 500 V is the closest benchmark — confirm your available fault current against that figure.
The 86 mm depth (3.39 in) means it clears most standard enclosure back-panels without hitting the door.
