3VA5210-6EF31-0AA0 - HFAS 100 Amp Circuit Breaker

3VA5210-6EF31-0AA0 - HFAS 100 Amp Circuit Breaker

The Siemens 3VA5210-6EF31-0AA0 is a 100 amp, 3-pole circuit breaker designed for standard three-phase protection in commercial and industrial systems. It’s part of the 3VA5 line, known for being dependable without overcomplicating things. This model uses a thermal magnetic trip unit, so it handles both overloads and short circuits in one package. The settings are fixed—100A for overload and 10x for instantaneous trip—which keeps things simple and predictable. If you’re not looking to fine-tune settings and just need reliable protection, that’s actually a benefit. With a solid interrupting rating and a compact footprint, it fits well into most panel setups and does its job without drawing attention to itself—which is exactly what you want from a breaker.
