Product details

What this breaker delivers

The IP20 rating applies with connected conductors; the handle area reaches IP40. Sealable, halogen-free, and silicon-free — suitable for environments with restricted material outgassing specs.

Listed as current production (active lifecycle stage). No NRND or end-of-life signals in the record. The part is quotable through standard Siemens distribution channels. For a firm lead time and pricing, raise an RFQ with your target quantity.

Installation notes

Depth of 70 mm and height of 110 mm fit standard enclosure cutouts; the front-profile width matches the 3-module format. Ambient temperature range −40 to 75 °C with up to 95 % humidity. Vibration resistance tested at 50 m/s² 25–150 Hz and 60 m/s² at 35 Hz (4 s). Supply frequency 50 Hz. Neutral conductor not switched. Combined terminals top and bottom (tunnel terminals not present). Insulation voltage Ui 440 V AC.
