Reading the table

Pitch: Centre-to-centre distance between poles, in mm. It must match the hole spacing on your PCB. Some parts list two pitches, such as 5.00 / 5.08 mm.
Poles: The range of position counts the part is made in, e.g. 2P – 24P.
Rated V / A: Rated voltage and current as printed in the catalogue.
Wire AWG: Wire range the clamp takes. A dash means no range is printed.
Torque: Tightening torque for the screw, as printed.
Withstand: Every part in the catalogue lists a withstanding voltage of AC 1500 V for 1 minute.
