Product details

The thermal-magnetic trip unit (TM-D) handles overloads and short-circuits in one package; no separate relay needed. Rated for distribution duty per EN/IEC 60947-2, Category A, with suitability for isolation. IK07 impact rating handles accidental tool bumps during commissioning.

Mounts on a backplate — horizontal or vertical, flat on the back. 12-module pitch at 9 mm per module (108 mm wide, 137 mm high, 80 mm deep). Connection pitch is 35 mm with spreaders, 27 mm without. Toggle control, grey (RAL 7016) housing. Local flag (green) indicates presence of auxiliary contacts. Earth-leakage protection is not built in — specify an external Vigi module if needed.
