I am having problems understanding what is meant by a 3,4,5-pole lighting contactor. Are these the number of poles(circuits) feeding the lighting contactor or is it the number of circuits that the lighting contactor switches on the output?
Is it typical to have the same number of poles feeding the lighting contactor as there are poles being switched?
Can anyone help me understand this lighting contactor terminolgy?
Thanks in advance!!!
