The breaking capacity is 200 kA Icu at 380/415 V AC 50/60 Hz per EN/IEC 60947-2 — that is the maximum fault current the breaker can safely interrupt without damage at that voltage level, which governs selectivity coordination in a distribution panel. At 660/690 V AC the Icu drops to 45 kA, so the application voltage must be checked against the full curve before specifying. The 4-pole configuration with neutral on the left suits 3-phase + N distribution, and the IP40 front face (IK07 impact rating) is standard for indoor panel mounting — not for washdown environments.
Front-side upside and downside connections simplify busbar and cable routing. The toggle control provides manual on/off and trip indication.
