3VA5320-5EF31-0AA0 - 200A Class MJAS 3-Pole Circuit Breaker Description
3VA5320-5EF31-0AA0 - 200A Class MJAS 3-Pole Circuit Breaker
If you’re working with a three-phase system and need dependable protection, the Siemens 3VA5320-5EF31-0AA0 is a solid choice. This is a 200-amp, 3-pole thermal magnetic circuit breaker from the 3VA5 series, built to handle everyday demands in commercial and industrial setups without overcomplicating things. It does exactly what you expect it to do—protect your system from overloads and short circuits—while giving you some flexibility where it counts. The adjustable overload range (160A to 200A) lets you fine-tune it to your setup, and the instantaneous trip range helps with coordination so everything doesn’t shut down unnecessarily during a fault. With a 400A frame and a 35 kA interrupting rating at 480V AC, it’s designed to deal with serious fault conditions without hesitation. It’s also compact enough to fit into most panelboards or switchgear without becoming a headache during installation. One thing to note: lugs aren’t included, so you’ll want to plan for that depending on your setup.
