3VA5225-6EF31-0AA0 - HFAS 250 Amp Circuit Breaker

3VA5225-6EF31-0AA0 - HFAS 250 Amp Circuit Breaker

If you’re dealing with serious power loads, you don’t want to second-guess your protection. The Siemens 3VA5225-6EF31-0AA0 is built for exactly that—solid, dependable circuit protection in commercial and industrial systems where failure isn’t an option. This 250-amp, 3-pole breaker is part of Siemens’ 3VA5 series, known for consistent performance and straightforward reliability. It uses a thermal-magnetic trip unit, which means it reacts as you expect—steady protection against overloads and a fast response when a short circuit occurs. No complicated setup, no guesswork. What you see is what you get. With a 35kA interrupting rating at 480V, it’s designed to handle high fault conditions without hesitation. And because the protection settings are factory set, you’re not spending extra time dialing things in—it’s ready to go to work.
