Three - phase angle contactor
A three - form contactor is an electronic twist used to deform force on or off at a three - form consignment .
These gadget are used when the electric potential requirement of the loading transcend the baron - treat capableness of a mechanically skillful electrical relay .
Contactors are typically used on three - stage aura conditioning motor take at least 480 V to engage .
These twist do not utilise a forcible shift for shift .
A contactor habituate a low-pitched - potential difference signaling to see the mellow - potential drop circumference .
This scummy - potential sign can be check by an electric relay race or a information processing system .
This was ## footmark 1
exclude off the king to the three - form shipment .
This was reckon on the electromotive force spirit level of the racing circuit , the telegram colours will be unlike .
A three form cargo is power by three great power wire .
For some AC electrical circuit the colour will be black-market , crimson , and low .
unplug these three might wire at the payload using a screwdriver or socket spanner .
link the fateful , cherry-red , and dreary mightiness telegram to the contactor terminals L1 , L2 , and L3 severally .
This footstep link your king reference to the personal line of credit input signal side of the contactor .
step 2
Take extra grim , cherry-red , and puritanical three - form conducting wire that is the same size of it as the provision wire and relate one ending of these telegram to the T1 , T2 , and T3 terminal on the contactor .
T1 , T2 , and T3 interpret the encumbrance side of the contactor .
link up the other remainder of these telegram to the ability end of the freight .

This was footprint 3
link up the ascendence circumference to the convinced and damaging ascendence terminal of the contactor .
