3VA5322-6EC31-0AA0 - 225A Class HJAS 3-Pole Circuit Breaker Description
3VA5322-6EC31-0AA0 - 225A Class HJAS 3-Pole Circuit Breaker
If you need a 225-amp 3-pole circuit breaker that you can install and trust, the Siemens 3VA5322-6EC31-0AA0 checks all the right boxes. It’s part of Siemens’ 3VA5 line, which is widely used in commercial and industrial setups where equipment protection isn’t optional—it’s critical. This breaker uses a thermal magnetic trip unit (TM230), meaning it reacts to both overloads and short circuits in a simple, proven way—no complicated programming or setup. The overload protection is fixed at 225A, so once it’s in place, it behaves exactly how you expect. At the same time, the adjustable instantaneous trip gives you some flexibility when dealing with fault conditions. Bottom line: it’s built for electricians, contractors, and maintenance teams who want something dependable without overthinking it.
Key Features and Benefits
- 225 Amp rating for reliable power distribution
- 3-pole design for standard three-phase systems
- Thermal magnetic trip (TM230) – handles overloads and short circuits in one unit
- 65 kA interrupting capacity @ 480V AC – ready for high fault conditions
- Fixed overload protection (Ir = 225A) – no guesswork during setup
- Adjustable instantaneous trip (5–10x In) – helps fine-tune short-circuit response
- Compact 3VA5 frame – fits well in modern panels and switchgear
- Solid Siemens build quality – designed for long-term, consistent use
