Product details

It is a 3-pole device rated for distribution applications, with a breaking capacity of 36 kA Icu at 415 V AC 50/60 Hz per IEC 60947-2 (85 kA at 240 V, 22 kA at 525 V, 8 kA at 690 V). The TM-D trip provides L (thermal overload) and I (magnetic short-circuit) protection, with the magnetic pickup fixed at a multiple of In typical of the TM-D curve.

At 240 V it handles 85 kA, so it coordinates well with a 100 kA upstream device in a high-fault location like a transformer secondary.

Mounts on a backplate (DIN-rail not supported — the 105 mm width and 161 mm height use four-bolt fixing). Front connection both upside and downside. IP40 enclosure protection, IK07 impact resistance. Toggle control, horizontal or vertical mounting allowed. Power dissipation is 9.45 W per pole — 28.35 W total at rated load; factor into enclosure thermal calculations.
