3VA5215-7ED31-0AA0 - CFAS 150 Amp Circuit Breaker

3VA5215-7ED31-0AA0 - CFAS 150 Amp Circuit Breaker

If you're dealing with serious power demands, you don't want to second-guess your protection. The Siemens 3VA5215-7ED31-0AA0 is built for exactly that kind of environment—where reliability matters and failure isn't an option. This 150-amp, 3-pole circuit breaker sits in the 3VA52 frame family, known for its consistent performance in commercial and industrial systems. With a 100kA interrupting rating at 480V, this breaker is ready to handle high fault currents without hesitation. It uses a thermal magnetic trip unit (TM210), which means you're getting dependable overload protection along with fast response during short circuits. The settings are fixed—150A for overload (Ir) and 10x In for instantaneous trips (Ii)—so there's no need to fine-tune or second-guess during installation. In plain terms: it does its job, and it does it well. That's exactly what you want when you're protecting expensive equipment and keeping systems online.
