3VA5245-7ED31-0AA0 - CFAS 45 Amp Circuit Breaker Description
3VA5245-7ED31-0AA0 - CFAS 45 Amp Circuit Breaker
If you just need a breaker that does its job and doesn’t cause problems later, this is one of those. The Siemens 3VA5245-7ED31-0AA0 is a 45 amp, 3-pole unit built for typical commercial and light industrial setups. Nothing flashy—but it handles what it’s supposed to handle. The big thing here is the 100kA interrupting rating at 480V, which gives you plenty of headroom if fault current is a concern. It’s got a fixed thermal magnetic trip (TM210), so there’s no adjusting or dialing things in. Overload protection is set at 45A, and if you get a short, it trips instantly at 10x that. That’s it. Simple. That’s usually what you want. Size-wise, it fits where it should. No surprises there.
