| Design Of The Product | For motor protection |
Rated interrupting capacity hits 100 kA at 400 V and 500 V, and 10 kA at 690 V, so it can handle high-fault panels without cascading upstream.
Spring-loaded terminals on the main circuit accept 2× (0.5 to 2.5 mm²) solid or stranded conductors, so wiring is tool-less and stays tight under vibration. Dimensions are 45 mm wide, 106 mm high, 97 mm deep — fits standard 45 mm modular device slots.
Alternative models and sibling configurations in the same Siemens series. For obsolete or discontinued parts, these models can serve as compatible replacements or functional alternatives for plant maintenance.
