3VA5322-7EC61-0AA0 - 225A Class CJAS 2-Pole Circuit Breaker

3VA5322-7EC61-0AA0 - 225A Class CJAS 2-Pole Circuit Breaker

If you’re dealing with serious electrical loads, you need protection that just works—no guesswork, no surprises. The Siemens 3VA5322-7EC61-0AA0 is built for exactly that. This 225-amp, thermal magnetic circuit breaker is part of Siemens’ proven 3VA5 line, designed to handle real-world conditions in commercial and industrial setups.What stands out here is the balance between simplicity and performance. You’ve got fixed overload protection set at 225A, plus an adjustable instantaneous trip range (5–10x), giving you solid defense against both sustained overloads and sudden faults. It’s a 2-pole breaker housed in a 3-pole frame, which gives you a bit more flexibility when fitting it into existing systems.

And with a 100 kA interrupting rating at 480VAC, this unit is ready for high fault-current environments where lesser breakers simply don’t cut it.
