The instantaneous magnetic short-circuit trip responds at 8.2 A, so it clears a bolted fault fast without waiting for the thermal bimetal to heat up — that's the coordination point the upstream feeder breaker needs to see.
Size S00 frame keeps the footprint compact: 45 mm wide, 96 mm deep, 97 mm tall. Clearance needs: 50 mm above and below, 30 mm to the sides, zero forward or backward. Screw-type terminals on top and bottom accept 2x (0.75 to 2.5 mm²) solid/stranded or 2x 4 mm², with a tightening torque of 0.8 to 1.2 N·m.
Key ratings in context
Surge voltage resistance is 6 kV. Operates across -20 to +60 °C ambient, with 10 to 95 % relative humidity. Shock resistance tested to 25 g / 11 ms per IEC 60068-2-27. Maximum installation altitude 2 000 m above sea level. Total typical power loss is 5 W — negligible for panel thermal budgeting, but worth noting if you're packing multiple units into a sealed enclosure.
