When using 3phase contactor, do I still need a separate 120v circuit to energize the coil ?

Contactor comes in different coil voltage range that depends on control voltage. If it is 120v then u connect phase to neutral across the coil.

can I use contactor to switch 24VDC 100aMP (source 1) OR 24VDC 100aMP (source 2) to a single load which need 24VDC 80AMP. When my source 1 fail to generate 24VDC, the load should automatically switch to source2.

@electricallectures Жыл бұрын

Be very careful to switch 24vdc . Bcz contactor rating are for switching AC. There are special DC coils to switch 100Amps

@MultiTHUNDER00 15 күн бұрын

how does the coil stay energized after releasing the green button, i understand that you use a parallel no contact but i don't get how it stays active after a single press, i mean how the current continuous to pass through the contanct mechanically. In my mind releasing the button even with the no contact shouldn't it stop the whole thing?

@electricallectures 15 күн бұрын

This is very basic usage of contactor. It energizes as soon as you press the push button. And when it energizes completely and plunger pulls the contacts, then it's auxiliary contacts also change their state. When no is used it change to nc and continue power across coil. This is called holding

What is the voltage applied for coil to make it electro magnet. 12volts, 24volts? How can we know the same. Is this voltage given saperate from addaptar?

@electricallectures 3 жыл бұрын

Its mentioned on each contactor. You can have different coil voltages ranges from 24v to 230v ac or dc. Its important you must apply voltage equal to rated coil voltage to make it electromagnet. High voltage will make it burn

Very less usually 25w to 100w coil. For 11kv contactor coil is around 220W. So it means less than 1A @220vac

24v dc 2no 2nc - 230v ac contactor will work on solar panel dc volt 0to30v. I am taking solar volt as reference to connect 230v ac line 1 and 2 switching function. When solar available line 1 to be connected . If solar not available then line 2 to be connected. My doubt is will this contactor work on solar dc volt.

@electricallectures 2 жыл бұрын

Not at all. Solar voltage is higher than rated contactor voltage. And normally for dc voltage you need dc components
