3VA4120-6ED34-0AA0 - 20Amp Circuit Breaker

3VA4120-6ED34-0AA0  -  20Amp Circuit Breaker

When you're working with electrical systems, the last thing you want is uncertainty. The Siemens 3VA4120-6ED34-0AA0 is built to do one job well—protect your equipment and keep things running safely. This is a 20 amp, 3-pole molded case circuit breaker designed for commercial and industrial setups where higher fault currents are a real concern. With a 65kA interrupting rating at 480V, it’s more than capable of handling serious electrical faults without hesitation. It uses a thermal-magnetic trip unit (TM210), which means it responds to both overloads and short circuits. The overload protection is fixed at 20 amps, so there’s no adjustment needed, and the instantaneous trip activates at 15 times the rated current to shut things down quickly when it counts. Bottom line—this is a straightforward, dependable breaker from a manufacturer that’s been doing this for a long time. It’s built to perform without overcomplicating things.
