Lighting Control
Schneider Ac magnetic contactor LC1D09M7 are often used to provide central control of large lighting installations, such as an office building or retail building. To reduce power consumption in the contactor coils, latching contactors are used, which have two operating coils. One coil, momentarily energized, closes the power circuit contacts, which are then mechanically held closed; the second coil opens the contacts.
Electric Motor Starter
Schneider Ac magnetic contactor LC1D09M7 can be used as a magnetic starter. A magnetic starter is a device designed to provide power to electric motors. It includes a contactor as an essential component, while also providing power-cutoff, under-voltage, and overload protection.
The Difference Ac Magnetic Contactor and Relays
A more complete list of the differences between a contactor and a relay would include the following:
Load capacity
Contactors are designed and built to handle much higher power switching applications than control relays. Relays are typically reserved for use with loads of around 5A-15A, and they are most often rated for 10A or less.
Contact standards
Contactors are almost always set up in a normally open (NO) configuration. This means that the circuit will only be established while the electromagnet in the contactor is receiving current. Relays are easy to find with both NO and NC contacts.
Protections and safety features
Contactors typically offer a much wider range of safety cut-offs and protections, reflecting the fact that they are designed for higher power applications. Indeed, a specific type of switch known as contactor overload relays is specifically designed for use in preventing machinery and power circuits from overheating.
AC 1 magnetic contactor
This type of contactor is helpful in resistive loads such as heater and electrical furnace, and non-inductive or slightly inductive loads, which means the load's power factor lies between 0.95 and 1.
AC 2 magnetic contactor
For starting of slip-ring motors. Suitable for use with retractable loads as a slip ring motor. They mostly prefer high torque current applications.
AC3 magnetic contactor
Suitable for starting and stopping loads at the motor is up to a speed of a squirrel cage motor. This type of contactor can withstand of high current continuously. Example – Elevators, lifts.
AC4 magnetic contactor
Suitable for frequent starting-stop motor circuit jogging and the reversal of the squirrel-cage motor rotation. Also used in rapid start/stop. Example-Cranes.
The Working Principle of LC1D09M7 Magnetic Contactor
A contactor driven by magnetic energy consists of a magnetic core (core and armature) and a coil that generates a magnetic field strong enough to overcome the forces of the springs that keep the two parts of the core apart. One of these parts, usually the armature, is integrally attached to the device and actuates the electrical contacts.
Electromagnet
The magnetic circuit comprises a (fixed) core, an armature (mobile), and the shadow loop, the latter required for electromagnets powered with alternating current. The magnetic circuit includes a small air gap in the "closed "position to prevent any remaining flux from holding the moving armature.
Core
The core is made of silicon steel sheets tightly bonded to reduce energy losses caused by the circulation of current parasites. Its function is to house the coil, concentrate its magnetic flux, and attract the armor.The armature is the moving element of the electromagnet. It is very similar to the nucleus, but unlike it, it does not have turns of shade. Its main function is to close the magnetic circuit and drag it to mobile contacts.
Coil
The force of attraction of the electromagnet is a function of the magnetic flux that goes through. To originate this flux, an excitation coil is housed in one of the columns of the electromagnet core. The reels can be wound on a spool of insulating resin.
The major structure of the Schneider Ac Magnetic Contactor LC1D09M7
Input and output terminals
The size and number of these terminals depends on the voltage of the incoming power and where the power source is single-phase or three-phase.
A magnet and a coil
The magnet is often a horseshoe magnet that fits through a core around which the coil is wound. The core is made from a non-ferrous material to ensure it doesn't retain a magnetic field when the power is off. Other designs have a rectangular or cylindrical magnet inside a coil-wound solenoid.
A spring
The function of the spring is to keep the contacts open and the power to the load off. It may push the movable contacts away from the yoke or pull from the other side. In some models designed for vertical installation, gravity may take the place of the spring.
An enclosure
The enclosure keeps all components electrically isolated and protects users from accidental exposure. The housing is made from plastic, Bakelite or Nylon 6.
How to Test a Ac Magnetic Contactor
Identify the L-side and T-side
First, turn off the circuit breaker or unplug the power line that leads to the equipment to be tested, containing the magnetic contactor. After that, you may pull out the wires located in the line side screws. You must recognize these wirings by using a pen or a clear tape as markers. Use your pen to write L-1, L-2, or L-3 on the clear tape and post it on the respective wirings.Next, pull out the wires from the contractor's T or terminal side and L-side. Identify and put marks on each wiring using T-1, T-2, and T-3 as names. This will ensure that each wiring has its corresponding side and also prevent any misreading in the next procedures.
Connect the Wirings to the Volt Ohmmeter
Turn the control switch on to energize the coil in the contactor. You should hear a clear clicking and humming sound. Other magnetic contactors have a visual hint once the coil is energized.Get the volt ohmmeter and turn it on. Make sure that the ohm is positioned in front of the selector switch. Then set the red lead into the ohm connector, the black lead on the common, and touch both leads together. The volt ohmmeter must read 0 ohms.Proceed to test the L-side with its corresponding T-side L-1 to T-1 with the red lead to the L-side and the black lead to the T-side. Check if the wirings read 0 ohms. If it does not, then that means that magnetic contact is bad and therefore the contact must be replaced.
Observe the Test
The readings on the volt-ohmmeter should generate the same reading of 0 ohms and direct short. If it does not, check if the coils are properly linked or try to cycle the control switch of the coil if you can hear a clear clicking sound. If you cannot hear a clear clicking sound, then check the voltage source of the coil.Turn the ohmmeter to volts and set the red lead into the volts connector of the meter and initiate power to the coil. Each lead must have direct contact with each coil connector. The reading of the meter must be the actual voltage supply. You should read the circuit specification to get the quantity of voltage. If the coil does not close even if the voltage is accurate, then you need to shut off the flow of energy.
Improved safety
Magnetic contactors are equipped with an auxiliary contact that opens when the coil is de-energized, providing a means for disconnecting the power supply to the induction motor. This improves the safety of the system by reducing the risk of electrical shock or short circuits.
Smooth starting
Magnetic contactors provide a smooth start to the induction motor by gradually applying power to the motor windings. This helps to reduce stress on the mechanical components of the motor, extending its life and reducing the risk of breakdown.
Overload protection
Magnetic contactors are equipped with an overload protection mechanism that will disconnect the power supply to the induction motor in the event of an overload. This protects the motor from damage and increases its reliability.
Easy control
Magnetic contactors are easy to control and can be connected to a control circuit or timer, allowing the induction motor to be started and stopped at specific times.
How to Choose LC1D09M7
Assessing Load Capacity
The contactor's rated voltage should equal the maximum voltage of the controlled circuit. Likewise, ensure that the rated current is higher than that of the controlled circuit. To maintain high-frequency equipment, such as motors, select a higher-rated contactor to ensure efficient operation and increased life.
Selecting the Correct Size
Contactor sizes correspond to the International Electrotechnical Commission (IEC) usage categories.Consider selecting a contactor one or two tiers above what you think you need. Otherwise, the safety and efficiency of the operating equipment may be compromised.
Understanding Coil Voltage
The coil voltage rating is the voltage needed to move the actuator that closes the contacts. For safety purposes, the lower the coil voltage, the better. However, it must at least match the incoming grid voltage.
Regularly detect the supply voltage of the contactor coil and prevent the coil from overheating when the voltage is too high.
The impact force is large when the magnetic system is closed, and the related parts and components are easily damaged. When the voltage is too low, the contactor closes slowly and it is easy to make motion. Mechanical resistance, the contacts are easy to sinter together, produce bad effects in the speed change or commutation, resulting in automatic control circuit failure.
Regularly clean it with a high-quality cleaning cloth or brush
If air is blown with dry compressed air, the air pressure must not exceed O.2MPa, and should be vented before use to vapor After the dust is blown away and used, these two points are often overlooked and bring undue trouble.
The core work surface should be regularly inspected to remove oil
Dust, and rust. Because of their presence can cause noise and the contactor does not release when the power is turned off, or the release action is delayed.It is necessary to regularly check the wear of moving parts to prevent mechanical wear and jamming, which will increase the scope of faults.
Regularly inspect each fastening connector for looseness, especially when the contactor mounting surface is subject to vibration.
Loosening of connecting fasteners will cause mechanical parts to become stuck and increase wear; loose conductive parts will cause poor conductive contact, increase contact resistance, cause overheating, discolor the metal parts, and burn the insulating material.
Regularly check the contactor contacts for black soot, metal particles, surface smoothness, and contact pressure, open distance and overtravel conditions.
Clean and align contacts and adjust contact pressure, open distance and overtravel are allowed. Within range. When cleaning the contacts, it is best not to use a trowel to flatten the contacts to contact the work surface (working point or wire). This will shorten the life of the contacts.
