1 Clearance Distances The clearance distance the shortest distance the air between two conductive parts.15: Nominal mains voltage for AC voltage systems based DIN IEC 38, V Rated impulse voltage for over voltage category I III IV 230 400 277/480° 1,500 2,500 4,000 6,000 400 690 2,500 4,000 6,000 8,000 1,000 4,000 6,000 8,000 12,000 1’The nominal mains voltage 500 included .g.6 Voltage Clearance and Creepage Distances The manufacturer should specify the rated voltage for every connector.1 Rated impulse voltage Table 4.160 4. The degree pollution has only slight influence on clearance distances 1. the rated conductor-conductor and conductor-earth voltage.6. The rated voltage depends number criteria: - Profile design the insert - Properties the insulating material - Clearance and creepage distances - Degree pollution: evaluation the environment which the device is operated DIN VDE 0110-1 states the principles for specifying the clearance and creepage distances well for determining other criteria. The following are the major criteria for determining the minimum clearance distance: - Rated voltage - Degree pollution (limited) - Inhomogeneous/homogeneous field - Overvoltage category 4.5 mm.1. 4. This can include more than one value, e. assumed that, changes the insulating material result aging, not influence the clearance distance.6. Additionally, VDE 0627 applies for connectors
