3VA5280-7ED31-0AA0 - CFAS 80 Amp Circuit Breaker

3VA5280-7ED31-0AA0 - CFAS 80 Amp Circuit Breaker

The Siemens 3VA5280-7ED31-0AA0 is the kind of breaker you use when failure isn’t an option. It’s rated at 80 amps with a 3-pole configuration and built on the 3VA5 Frame 250 platform, giving you solid protection in commercial and industrial setups where higher fault currents are part of the job. With a 100kA interrupting rating at 480V, this breaker is made to handle tough conditions without hesitation. It uses a thermal magnetic trip unit (TM210), which is about as straightforward and reliable as it gets. The overload protection is fixed at 80 amps, and the instantaneous trip is set at 10 times the rated current—so if something goes wrong, it reacts fast and helps limit damage. There’s no unnecessary complexity here. It’s a dependable, well-built breaker that does exactly what it’s supposed to do—protect your system and keep things running.
