I have just joined this forum.
My fist question is;

I am trying to become a little more competant in selection and ordering of the appropriate electrical 3 phase contactors in my work place.

How should I best organise our contactors and relays for ease of location and selection for jobs ?
Should I categorise them in way of coil voltage, then utilization category- ie (AC3), then kW rating ?

Which way would help me identify the correct variables to take into consideration, in the selection process for replacing/installing or ordering a contactor for an electrical installation ?

Cheers
