The safety clearance distances are as per the attached table. These values are given for AC voltage; however these values are same as in case of DC voltage.
Note: With DC application the safety clearance in front of contactor will be 100mm (X1) and up to the arc chamber will be 150mm (X2) because the voltage per pole is limited to 440VDC.
