It is a 3-pole device in the compact S00 frame size, rated for 690 V at AC-3 duty and 50/60 Hz. Power loss is 6 W typical. This is a current-production part (lifecycle stage: current).
The 0.8 A rated current and Class 10 trip curve mean this breaker is sized for a small motor — fractional horsepower, say a 0.25 kW three-phase motor at 400 V. The 690 V AC-3 rating covers switching motor loads at line voltage up to that level. The S00 frame (45 mm wide, 96 mm deep, 97 mm high) fits the standard DIN-rail footprint; clearance requirements are 50 mm above and below, 30 mm to the sides, and zero forward/backward clearance needed.
Integration — DIN rail and wiring
Accepts 2× (0.5 to 1.5 mm²) or 2× (0.75 to 2.5 mm²) solid or stranded wire on main contacts; AWG equivalents 2× (18 to 12) or 2× (20 to 16). Auxiliary contacts use screw terminals, 2× (0.5 to 1.5 mm²) or 2× (0.75 to 2.5 mm²). Terminal torque for main contacts: 0.8 to 1.2 N·m. The transverse auxiliary switch design allows side-by-side ganging without extra spacing beyond the 30 mm side clearance.
