3VA5222-5EC31-0AA0 - MFAS 225 Amp Circuit Breaker Description
3VA5222-5EC31-0AA0 - MFAS 225 Amp Circuit Breaker
The Siemens 3VA5222-5EC31-0AA0 is one of those breakers you install and don’t have to think about again. It’s built for straightforward, reliable protection in 3-phase systems—nothing fancy, just solid performance where it counts. Rated at 225 amps with a 35kA interrupting capacity at 480V, it’s made to handle real-world electrical faults without hesitation. The thermal magnetic trip unit keeps things simple: overload protection is fixed at 225A, and short-circuit protection kicks in instantly at 10 times the rated current—no fine-tuning, no extra setup—just predictable operation. It’s also part of Siemens’ 3VA5 line, so you’re getting a design that’s widely used and trusted across commercial and industrial setups. And with its relatively compact size, it fits into panels, making installation a breeze.
