3VA5225-7ED31-0AA0 - CFAS 250 Amp Circuit Breaker

3VA5225-7ED31-0AA0 - CFAS 250 Amp Circuit Breaker

The Siemens 3VA5225-7ED31-0AA0 is one of those breakers you spec when you don’t want callbacks later. It’s a 250 amp, 3-pole unit built on the 3VA52 frame, and it’s designed to deal with real-world conditions—not just ideal ones. With a 100kA interrupting rating at 480V, it’s more than capable of handling high fault current levels you’ll see in larger commercial or industrial setups. The thermal magnetic trip (TM210) keeps things simple—fixed at 250A for overload, with an instantaneous trip at 10x the rating. No fine-tuning, no overthinking. It just does its job. It’s a solid choice if you’re putting together a panel where reliability matters more than bells and whistles.
