It's built for distribution duty in fixed-mount backplate panels, with front-connect terminals at a 25 mm pitch.
Breaking capacity drops with voltage: 60 kA at 240 V AC, 30 kA at 400 V AC, 20 kA at 440 V AC (all per EN/IEC 60947-2). The F code in the short name (EZS100F) signals the 60 kA class at the highest common voltage. For a 400 V distribution board with a 25 kA prospective fault current, this breaker holds 5 kA headroom — enough for most commercial panels. The integral instantaneous protection is rated 300 kA, which covers the magnetic trip's ability to clear a bolted fault before the contacts part.
Fixed backplate mount, 130 mm high × 75 mm wide × 60 mm deep. Front-connect terminals at 25 mm pitch — standard for busbar or cable lug connection. IP40 enclosure (finger-safe, not dust-tight) and IK07 impact rating.
