3VA5225-7EC31-0AA0 - CFAS 250 Amp Circuit Breaker Description
3VA5225-7EC31-0AA0 - CFAS 250 Amp Circuit Breaker
When you’re dealing with serious electrical loads, you don’t want to second-guess your protection. The Siemens 3VA5225-7EC31-0AA0 circuit breaker is designed for exactly that kind of environment—where reliability isn’t negotiable, and downtime costs real money. This 250-amp, 3-pole breaker is part of the well-known 3VA52 series and is built to handle demanding commercial and industrial applications. What really sets it apart is its 100kA interrupting capacity at 480V, giving you the confidence to handle high-fault conditions without hesitation. It uses a thermal magnetic trip unit (TM230) with fixed settings, which means fewer variables and less room for error. The overload protection is set at 250A, and the instantaneous trip kicks in at 10 times the rated current. In plain terms, it reacts fast when something goes wrong, without needing constant adjustment or fine-tuning. If you’re replacing an existing breaker or building out a new system, this is the kind of component you install once—and trust to do its job.
