Schneider AC contactors.
LC1D5050 stands for:
The maximum current through the contactor is 50A, and if it exceeds 50A, the contactor will burn out.
Schneider contactors are divided into AC contactors (voltage AC) and DC contactors (voltage DC), which are used in power, distribution and electricity consumption occasions. Contactor broadly refers to an electrical appliance that uses a coil to flow through an electric current to generate a magnetic field and close the contact to control the load.
Function: In electrical engineering, because it can quickly cut off the main circuit of AC and DC and can frequently connect with the high-current control circuit (up to 800A) of the device, it is often used as a control object for the motor can also be used to control the power load of plant equipment, electric heaters, machine tools and various power units.
The contactor not only turns the circuit on and off, but also provides protection against low voltage release. The contactor has a large control capacity, which is suitable for frequent operation and long-distance control, and is an automatic control system.
one of the important elements.
Schneider circuit breakers are divided into high-voltage circuit breakers according to their range of use.
and low-voltage circuit breakers, the division between high and low voltage is relatively blurred, and generally more than 3kV is called high-voltage electrical appliances.
Low-voltage circuit breakers are also known as automatic switches, commonly known as air switches.
It also refers to the low-voltage circuit breaker, which is an electrical appliance that has both manual switching function and automatic loss of voltage, undervoltage, overload, and short circuit protection. It can be used to distribute electrical energy and start asynchronous motors infrequently.
Protection of power lines and motors.
When they have serious overload or short circuit and undervoltage and other faults, they can automatically cut off the circuit, and their function is equivalent to a fuse.
type switch and underheating relay.
and so on. In addition, it is generally not necessary to change parts after the fault current is broken, and it has been widely used.

Generally, the three-phase contactor has a total of 8 points, three inputs, three outputs, and two control points. The output and input are corresponding, and it is easy to see. If you want to add self-locking, you also need to connect the wire from one of the terminals at the output point to the control point.
Once you know the principle, you should figure out the contacts of the external power supply, that is, the two contacts of the coil, which are generally at the lower part of the contactor, and on each side. The other inputs and outputs are generally in the upper part, and you can see it at a glance. Also pay attention to the voltage of the external power supply (220V or 380V), which is generally marked as yes.
And pay attention to whether the contact point is normally closed or normally open. If there is a self-locking control, it is enough to sort out the line according to the principle.

Schneider contactor LC1D09FD how to see coil voltage, DC or AC?
Hello dear, Schneider contactor LC1D09FD how to see the coil voltage, DC or AC? The coil voltage can be seen from the outer packaging, and the coil voltage can also be seen from the front of the contactor. The imaginary nameplate on the side of the contactor is not marked with coil voltage.
LC1D stands for Schneider contactor, 09 stands for 9A current can be turned on and off for this contactor, F stands for positive voltage rating, and D stands for standard DC coil. I hope mine will help you, dear.

The AC contactor is used to turn on or off the circuit by gaining and losing power from the coil. Generally, the coil (A1, A2) is controlled by a switch or PLC output, the normally open contact is used to maintain the power supply of the coil, and the inlet and outlet ports are connected to single-phase or three-phase circuits.

LC1D indicates that the product is a single contactor of the Tesys and D series.
18 means that the current is 18 amps.
10 indicates a pair of normally open contacts.
M5N indicates the coil voltage level.
AC 220V, 50Hz.

Schneider contactor LC1D50 and LC1D50A are mainly different in appearance.
1. LC1D50A is a new product, the appearance is more beautiful, and the internal structure is no different from LC1D50.
2. The one with A is the newly launched product series, the EverLink series, which is a little narrower and longer than the one without A.
3. The main contact of the contactor everlink function is generally a normally open contact, while the auxiliary contact often has two pairs of normally open contact and normally closed contact, and the small contactor is often used as an intermediate relay with the main circuit. The contacts of the AC contactor are made of silver-tungsten alloy, which has good conductivity and high temperature ablation resistance. The power of the AC contactor action comes from the magnetic field generated by the AC through the coil with the core, and the electromagnet core is stacked by two mountain-shaped fine silicon steel sheets, one of which is fixed with a coil, and the working voltage can be selected in a variety of ways.
In order to stabilize the magnetic force, the suction surface of the iron core is added with a short differential ring. After the AC contactor loses power, it relies on a spring to reset. The other half is the movable core, which is constructed in the same way as the fixed core, and is used to drive the closure and disconnection of the main and auxiliary contacts.
The contactor above 20 amperes are equipped with an arc extinguishing cover, which uses the electromagnetic force generated when the circuit is disconnected to quickly break the arc and protect the contact.
4. The contactor EverLink can be operated at a high frequency, and the maximum operating frequency can reach 1200 times per hour when the power is turned on and cut off. The service life is high, with mechanical life typically ranging from millions to 10 million cycles, and electrical life typically ranging from hundreds of thousands to millions of cycles.
5. Contactors are divided into AC contactors (voltage AC) and DC contactors (voltage DC), which are used in electricity, distribution and consumption. Contactor in a broad sense refers to the electrical appliances that use the current flowing through the coil to generate a magnetic field and close the contact to control the load in industrial electricity.

It is placed in the control circuit part and is used to lock (connected in parallel on the start button) to achieve the purpose of continuous operation.
First of all, the three-phase power supply is connected to the main contacts L1, L2, L3 of the contactor, and then three wires are connected to the three binding posts of the motor from the T1, T2, and T3 dug from the contactor beam, and the above is the main circuit. Control circuit: lead out a wire from L1 to connect the stop button (the slag base of the stop button is normally closed, and the start button is normally open, this should be known!)
From the stop press the slag button out of the start button and the contactor auxiliary contact at one end, and then from the other end of the start button to the other end of the auxiliary contact (this part is also self-locking), from this end out of the wire coil A1, coil A2 out of the wire connection L2 or L3.
Generally, the three-phase contactor has a total of 8 points, three inputs, three outputs, and two control points. The output and input are corresponding, and it is easy to see. If you want to add self-locking, you also need to connect the wire from one of the terminals at the output point to the control point. >>>More
Contactors. Control protection circuit, for reference:
AC contactor wiring: AC contactor often adopts three arc extinguishing methods: double-fracture electric arc extinguishing, longitudinal seam arc extinguishing and grid arc extinguishing. It is used to eliminate the arc generated by the dynamic and static contacts in the process of splitting and closing. Contactors with a capacity of more than 10 A have arc extinguishing devices. >>>More
Contactor working principle:
When the coil is energized, the static iron core generates electromagnetic attraction and engages the moving iron core, because the contact system is linked with the moving iron core, so the moving iron core drives the three moving contacts to run at the same time, and the contacts are closed, so as to connect the power supply. When the coil is de-energized, the suction disappears, and the linkage part of the moving core is separated by the reaction force of the spring, so that the main contact is disconnected and the power supply is cut off. >>>More
