3VA5340-6EC31-0AA0 - 40A Class HJAS 3-Pole Circuit Breaker Description
3VA5340-6EC31-0AA0 - 40A Class HJAS 3-Pole Circuit Breaker
If you’re looking for a straightforward Siemens breaker that does exactly what it’s supposed to do, the 3VA5340-6EC31-0AA0 fits the bill. It’s a low voltage molded case breaker built on the 3VA platform and uses a thermal-magnetic trip unit with fixed settings. No adjustments, no guesswork. Once it’s in, it just works. This model is rated 40 amps and delivers 65kA of interrupting capacity at 277 volts, which makes it suitable for systems where fault current isn’t something you want to underestimate. It’s a single-pole breaker housed in a two-pole body, a setup commonly used in certain Siemens panel designs. Load-side lugs are already installed, so you’re not hunting for extra hardware during installation.

Where It Works Best
- This breaker is typically used in commercial and industrial panels, especially where a fixed trip breaker is preferred over adjustable models. It’s a solid fit for panelboards, switchboards, and equipment protection circuits running at 277 VAC. The high interrupt rating makes it useful in locations where available fault current is on the higher side.
