Hook up contactor

How do you wire a control coil to a contactor?

Use the mounting screws that are supplied by the manufacturer of the enclosure or the contactor, and the appropriate screwdriver. Strip all the wires that will be connected to the control coil and the contactor terminations with the wire strippers. Remove approximately ½ inch of the wires insulation to expose the bare copper wire.

How do you connect a contactor to a circuit board?

Steps Acquire the contactor. Study the contactor manufacturer information. Check for an auxiliary output contact. Route the wires. Strip the wires. Wire the inputs and the auxiliary contacts. Energize the contactor. Connect the outputs.

How do I select a contactor for my motor?

Choose your motor horsepower, input voltage and single or 3 phase from the drop downs and the calculated full load amperage is displayed. You should next confirm the control voltage to be used to power the contactor. This can be the same as the line voltage, however often a lower voltage is selected for the contactor for safety purposes.

Where do the lights connect to the contactor?

The lights connect to the output ports on the contactor. The contactor will have space for the red power wires coming in from the photocell, circuit breaker, and lights. The black power wires will need to be tied together externally, such as through a wire nut.

How do you wire a contactor to a contact block?

Use a screwdriver to loosen the holding screws in the contact blocks for the wires. Insert the wires only so far that no insulation is pushed into the contact area of the block. Make sure that no stray strands are jutting out from the contact block. Tighten the screws on the contact blocks. Energize the contactor.

How do you Mount the coil and contactor?

The coil mounts, usually on a Din rail, then the contactor mounts to it. You should have two terminals marked A1 & A2, these are for the coil. As has been mentioned, the coils come in various voltages. Also, as has been said, if youre starting from scratch, get something that is similar to your control voltage.

How do I install the control coil on my enclosure?

Use the mounting screws that are supplied by the manufacturer of the enclosure or the contactor, and the appropriate screwdriver. Strip all the wires that will be connected to the control coil and the contactor terminations with the wire strippers.

How do I strip the wire from the control coil?

Strip all the wires that will be connected to the control coil and the contactor terminations with the wire strippers. Remove approximately ½ inch of the wires insulation to expose the bare copper wire.

How do I connect a contactor to a circuit board?

Connect the power feed wires to the top side of the contactor to the terminals marked L. These too will be marked in the same numerical order as in step 4 above --L1, L2 and L3. Match the input and output side of the wires if you are using fewer than the number of contactor terminals provided for the wiring you are connecting.

What is the purpose of a contactor on a light switch?

This closes the relay or contactor and energizes the lighting circuit which are in the US often 240 Volts rather than just the 120 Volts used in residential lighting. Some times the same arrangement is used in residential lighting but with 120 volts. Saving all those Most contactors are just a high current relay.

How do contactors and relays work?

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

What type of wire is used in a light switch contactor?

Most contactors are just a high current relay. When there are a lot of lights to be controlled by a single switch then a small wire such as bell wire can be used for the switch leg. It’s small size makes it cost much less and it doesn’t have to carry much current.
