5SY6204-7 - 4Amp Circuit Breaker

5SY6204-7 - 4Amp Circuit Breaker

The Siemens 5SY6204-7 is one of those components you don’t think about much—until you need it to work flawlessly. Designed for 480VAC applications, this 2-pole, 4-amp miniature circuit breaker provides dependable protection against overloads and short circuits in a wide range of commercial and industrial setups.

It’s compact, straightforward, and easy to install. The DIN-rail mounting clips in quickly, which makes a difference when you're working inside a crowded panel. And because it doesn’t take up much space, it’s a practical choice for tighter layouts where every inch matters.

What you’re really getting here is consistent performance. The thermal-magnetic trip mechanism reacts the way it should—no surprises. It handles fault conditions quickly while staying stable during normal operation. That balance is key when you’re protecting sensitive circuits or equipment that can’t afford interruptions.

If you’ve worked with Siemens breakers before, this will feel familiar—in a good way. It’s built to do its job quietly and reliably over time.
