It belongs to the ComPacT NSX family, designed for distribution applications where selectivity and coordination matter in panel builds. The TM-D trip provides L (thermal overload) and I (magnetic short-circuit) protection, adjustable via the front dials. Rated 100 A at 50 °C (same at 40 °C), this breaker handles the standard commercial and industrial load range. The breaking capacity is what sets the F-frame apart: 36 kA Icu at 380/415 V AC, 85 kA at 220/240 V, and 8 kA at 660/690 V — all per IEC 60947-2. For a 415 V distribution board, that 36 kA rating gives solid fault-clearing headroom without stepping up to the H-frame. Mounts on a backplate, not DIN rail — the 161 x 140 x 86 mm (H x W x D) envelope fits standard panel cutouts. Front connection both top and bottom simplifies busbar and cable routing. The toggle handle gives clear visual indication of breaker state for panel walkdowns.
