The thermal-magnetic TM-D trip provides inverse-time overload protection (thermal element) and instantaneous magnetic short-circuit protection. The 20,000 electrical cycles at rated current (In/2 at 440 V) and 20,000 mechanical cycles give a solid service life for a distribution breaker — not a switching device, but rated for occasional load-break duty. Mounting is on a backplate, not DIN rail — the 108 mm width and 137 mm height occupy 12 module pitches of 9 mm. Connection is front-facing via compression lugs or busbars, with a 35 mm pitch when using spreaders, 27 mm without.
The breaker is suitable for isolation per IEC 60947-2 — the green flag indicator on the front shows presence of auxiliary contacts, and the toggle control provides visible break indication.
Integration into the panel
Mounts on a backplate in horizontal or vertical orientation, flat on the back. The 80 mm depth fits standard enclosures. Front connection for both line and load sides. Relative humidity range of 0 to 95 % covers most non-condensing indoor environments. The grey (RAL 7016) colour is standard for Schneider's ComPacT range.
