Application Notes
- NO (No‑Overload): 45 kW / 60 HP (94 A) for constant torque, no overload duty
- LD (Light‑Duty): 45 kW / 60 HP (90 A) for 110% overload (1 min/5 min)
- HD (Heavy‑Duty): 37 kW / 50 HP (75 A) for 150% overload (1 min/5 min)
- Cabinet Mounting: IP20 requires installation in a closed, ventilated cabinet; ensure adequate airflow for forced cooling.
