 Re: Contactors : and how they work
oh f**k here we go
two circuits one to energise the coil one to power the lights
1st circuit ,wire from your mcb(control circuit ) to your light switch (normal everyday thing)then back to your a1 terminal .neutral of this circuit is taken straight to the a2 terminal
2nd circuit (power circuit ) is taken through the terminals of the contactor (l1,l2,l3...t1,t2,t3)and back out to your lights .neutral is taken straight to the lights
dont forget the relevant earths and make sure the contactor is correctly sized ,also check the control voltage info
this is the most simple way of doing things it gets fun when you add pir sensors ,timers photocells................
have i missed anything? |
