Modular contactors

The choice of contactor depends upon a number of parameters :

• the nature of the supply
  
• the power it is switching
  
• the characteristics of the load
  
• the control voltage required
  
• number of operations
  

All contactors ratings are for AC1 loads only - if the load differs from AC1 the contactor may need de-rating.

Lighting systems with electronic ballast may cause high inrush current peaks, which can damage the contactors after several switchings.

The new Hager web-based tool is developed to calculate the maximum amount of lamps that can be connected to hager contactors.
