Its thermal overload release (CLASS 10) and magnetic short-circuit trip work together to clear faults before the motor insulation or upstream contactor takes damage. The 10 A rated operational current at AC-3, 400 V means it directly protects a motor drawing up to that full-load current in a standard 400 V line.
The 45 mm width (three 15 mm modules) fits a standard distribution board or motor control centre slot. Screw-type terminals on top and bottom accept 2x (0.75 to 2.5 mm²) solid/stranded or 2x 4 mm², torque to 0.8–1.2 N·m.
Operates from -20 to +60 °C, stores from -50 to +80 °C, and handles 10–95 % relative humidity. Shock rated at 25 g / 11 ms per IEC 60068-2-27, surge voltage resistance at 6 kV. The 50/60 Hz AC-3 rating at 690 V maximum covers most global industrial supplies. Power loss totals 7 W typical — negligible for panel thermal budgeting.
