Key Selection Notes
- Power matching rules
Normal duty: Pumps, les fans, convoyeurs (light starting)
Heavy duty: Compressors, crushers, mélangeurs; select by heavy-duty power
Exemple: ATS48D88Q fits 45kW (400V normal), 37kW (400V heavy)
- Taille & weight groups
Petit (D17Q~D47Q): 160mm de large, 4.9kilos, for small motors
Large (D62Q~D88Q): 190mm de large, 8.3kilos, better cooling for medium/high power
- Remplacement & upgrade suggestions
Voltage upgrade: Q (230~415V) → Y (208~690V), par ex., ATS48D88Q → ATS48D88Y
Performance upgrade: ATS48 → ATS480 series
Economic option: ATS22 series same current models
