3VA5290-7EF31-0AA0 - CFAS 90 Amp Circuit Breaker Description
3VA5290-7EF31-0AA0 - CFAS 90 Amp Circuit Breaker
The Siemens 3VA5290-7EF31-0AA0 is the kind of circuit breaker you install once and don’t have to think about again. It’s built for dependable protection in real-world conditions—whether that’s a busy commercial panel or a demanding industrial setup. This is a 90-amp, 3-pole breaker from Siemens’ 3VA5 series, designed to handle serious fault conditions with a 100kA interrupting rating at 480V. In practical terms, that means it’s ready to step in fast when something goes wrong, helping prevent damage to your equipment and keeping downtime to a minimum. It uses a thermal magnetic trip unit (TM240) with fixed settings. The overload protection is set at 90 amps, and the instantaneous trip kicks in at 10 times that. No adjustments, no fine-tuning—just consistent protection that works the way it should right out of the box. If you prefer equipment that’s straightforward, reliable, and backed by a well-known name, this breaker fits the bill.
