SIRIUS size S00 motor protection circuit breaker — 0.5 A, Class 10
It carries a rated operational current of 0.5 A at 690 V AC-3, with a thermal overload release and a magnetic short-circuit trip. Three poles for the main current circuit, screw-type terminals accepting 2x (0.5 to 1.5 mm²) solid or 2x (0.75 to 2.5 mm²) stranded. The S00 frame keeps the width at 45 mm — a single module width on standard DIN rail, which matters when you are packing multiple feeders into a compact panel.
Panel integration and clearances
Clearance requirements: 50 mm upwards, 50 mm downwards, 30 mm to the side, zero forwards or backwards. That 50 mm above and below is the ventilation zone for the thermal bimetallic release — pack closer and you derate the trip curve. The S00 footprint (45 mm wide, 97 mm high, 96 mm deep) fits standard distribution boards and motor control centre buckets. Relative humidity 10 to 95 % during operation. Shock resistance 25g / 11 ms per IEC 60068-2-27.
Substance prohibitance date 05/01/2012 — the part was RoHS-compliant well before the current RoHS 3 deadline. Surge voltage resistance rated 6 kV, which covers the impulse withstand requirement for most industrial control panels per IEC 60947-1.
