SUITABLE APPLICATIONS & EQUIPMENT
CAPACITY SELECTION GUIDANCE
To determine if a 1200 kVA rating is suitable for your application, calculate your total continuous connected load in kVA (or kW divided by operating power factor, typically 0.8). For loads with heavy motor-starting inrush currents, a 20% to 30% safety margin is recommended. Selection depends on connected load; contact our engineering team for sizing assistance.
