How does a contactor switch a switch a circuit?
Contactors and relays are operated by applying a voltage to the coil of an Electro-magnet, which will cause a switch, (or several switches) to close. The circuit that applies the voltage to the coil is referred to as the control circuit , because it controls the main device that the contactor or relay is switching.
How contactor is connected?
Contactor Connection Procedure Generally the magnetic coil of a contactor is designed to operate at a low voltage such as 230V AC, 110V AC, 24V DC, etc. So provide the power supply to the magnetic coil as per requirement. 2. Connect the main power supply terminal with the incoming terminals of the contactor.

What are the terminals on a contactor?
The L1, L2, and L3 terminals are where the power wires connect to the contactor. The T1, T2, and T3 terminals are where the device wires connect to the contactor. The L1 contact connects to the T1 contact, the L2 contact connects to the T2 contact, and the L3 contact connects to the T3 contact.
How do you set up a contactor?
Break your circuit, L N E through your contactor. Link a permanent live and a neutral from your supply to your coil (Al + A2) then use your switch feed to your photocell from A1, and switch the wire to the switched phase of your contactor load. This should now open when light, close when dark.
Does a contactor need a neutral?
You still need a neutral going to the load. We need both hot and neutral at the coil side of the relay to make the coil pull in to make the contact.
What does l and t mean on a contactor?
With "L" 1,2,3, the L = "Line", meaning the incoming supply line. For the load side, "L" already had a different meaning, so the the label is T 1,2,3, with "T" = Terminus, meaning the exit point, ie going to the last thing connected in the circuit.
What are the A1 and A2 terminals on a contactor?
What Do A1 and A2 Mean on a Contactor? A1 and A2 on a contactor typically refer to either end of the electromagnetic coil assembly. Most contactor manufacturers use A1 and A2 to designate the two terminals connecting electrical power to the contactor's magnetic coil.

What are 13 and 14 on a contactor?
Many contactor manufacturers use the designations A1 and A2 for the terminals that connect power to the magnetic coil. Likewise, many manufacturers use the designations 13 and 14 for the terminals of normally open auxiliary contacts. Auxiliary contacts are operated by the magnetic coil just like the main contacts.
Whats the difference between a contactor and a relay?
A contactor joins 2 poles together, without a common circuit between them, while a relay has a common contact that connects to a neutral position. Additionally, contactors are commonly rated for up to 1000V, while relays are usually rated to only 250V.Contactor vs Relay: What's the Difference? - Springer Controls ...https://springercontrols.com › news › contactors-vs-relayshttps://springercontrols.com › news › contactors-vs-relaysSearch for: Whats the difference between a contactor and a relay?

How does a electrical contactor work?
Operating Principle of a Contactor:The current passing through the contactor excites the electromagnet. The excited electromagnet produces a magnetic field, causing the contactor core to move the armature. A normally closed (NC) contact completes the circuit between the fixed contacts and the moving contacts.The Basics of a Contactor & Types - c3controlshttps://www.c3controls.com › white-paper › basics-of-con...https://www.c3controls.com › white-paper › basics-of-con...Search for: How does a electrical contactor work?
