3VA5222-5ED31-0AA0 - MFAS 225 Amp Circuit Breaker

3VA5222-5ED31-0AA0 - MFAS 225 Amp Circuit Breaker

When you’re dealing with power distribution, you don’t want surprises. The Siemens 3VA5222-5ED31-0AA0 is the kind of breaker you install and don’t have to think about again—it just does its job. This is a 225-amp, 3-pole breaker built on the 3VA5 platform, designed for everyday use in commercial and industrial setups. It’s rated for 35 kA at 480V, so it can handle serious fault conditions without hesitation. Whether you’re protecting equipment or keeping a facility online, that kind of capacity matters. It uses a thermal magnetic trip unit (TM210), so you’re covered for both overloads and short circuits. The settings are fixed—overload protection is set at 225A, and instantaneous trip is locked at 10x the rated current. No fine-tuning, no extra setup. Install it, wire it, and you’re good. For contractors and maintenance teams, that simplicity is usually a plus. Fewer adjustments mean fewer mistakes and faster installs.
