3VA5325-6EF31-0AA0 - 250A Class HJAS 3-Pole Circuit Breaker

3VA5325-6EF31-0AA0 - 250A Class HJAS 3-Pole Circuit Breaker

When you’re working with higher loads, you need a breaker that just does its job—no surprises. The Siemens 3VA5325-6EF31-0AA0 is a 250 amp, 3-pole circuit breaker designed for solid, dependable protection in commercial and industrial systems. It uses a thermal magnetic trip unit (TM240), which means it handles both overloads and short circuits without overcomplicating things. Under normal conditions, it keeps everything running smoothly. When there’s a fault, it reacts fast to help prevent damage. One thing that stands out here is the adjustable overload range (200A–250A). Instead of being locked into a fixed setting, you can match the breaker to your actual load. That’s a practical feature, especially if your system isn’t perfectly static. Built on a 400A frame (3VA5 platform), this breaker also gives you some flexibility if your setup changes down the line.

Key Features and Benefits
