Its CLASS 10 trip characteristic means it will trip within 10 seconds at 7.2× the thermal setting — fast enough to protect standard IEC motor windings during locked-rotor events.
The 45 mm width is a standard 2-module footprint — it occupies two 22.5 mm slots on the rail, leaving room for auxiliary contact blocks or a separate contactor alongside. Terminal screws on the main circuit are M4, accepting 2x (1…2.5 mm²) or 2x (2.5…10 mm²) solid or stranded copper.
The rated insulation voltage spans 20…690 V. Ambient operating temperature range is -20…+40 °C; storage and transport range is -50…+80 °C. Clearances: 70 mm above and below, 30 mm to the side, zero forward or backward — useful for panel layout planning.
