Can Schneider AC contactor coil voltage AC220V be used in AC245V voltage?

The range of grid anomalies allowed in our country.

1) Voltage fluctuations. Fluctuations in grid voltage are often caused by large increases or decreases in grid load. For example, the voltage tends to be low during peak power consumption and high when equipment is down. The impact of voltage fluctuations in the grid is significant.

The national standard has the following provisions on the voltage fluctuation level:

Voltage level: Class A, Class B, Class C.

Volatility range: 5%, 7%, 10%, 10%.

2) The range of power grids in various places is basically in the above range, and the fluctuation of electrical appliances is 15%.If 30% of the range will cause major accidents, such as the Shenyang Bureau "11 15" accident, the southeast power grid of Jinjin, Henan power grid on July 1 overload trip accident.

3) A number of IT high-tech enterprises from Suzhou, Nanjing and other places put forward the requirements for power supply quality and reliability to power supply companies, which clearly reflects the realistic development trend of power quality. In other cities like Shanghai and Beijing, the mains voltage is also very stable. The power grid structure is fragile and prone to fluctuations in the main areas such as Shanxi, Henan, Guizhou and other places.

Therefore, it is generally calculated according to grade B, plus or minus 10%, and the coil voltage AC220V can be used in the AC245V voltage.

If it is a stable 245V, it should be possible, and generally the voltage is allowed to fluctuate within a certain range.

This is a bit dangerous, but generally speaking, like this kind of product abroad, there is still a relatively large margin, and there is no immediate damage to the situation, but the life is definitely not as good as not overworking, it is recommended to find a more pressure-resistant one.

Absolutely, AC220V, can work reliably from 20V, 200V to 240V.

OK. There is no impact.

220V is originally ranged, and 230V is normal.

Yes, it can be used normally without any effect.

Absolutely. It didn't make much of a difference. (It is recommended to use domestic, such as CHINT products).

For an AC contactor with a rated voltage of 220V, a voltage fluctuation of 10V will not have any effect on it. Can be used.

The voltage of how many volts is used in the AC contactor mainly depends on the coil, and the coil in the AC contactor can be replaced to use different voltages.

For example, Schneider's model you said can have AC 36V, 110V, 220V, 380V, DC 24V, and so on.

Coil voltage see here.

The contactor does not engage when there is voltage, which is caused by the open circuit of the contactor coil.

Check the contactor coil and replace one if it is damaged.

The Schneider contactor circuit board plays a protective role, because there is induced electricity in the circuit, and it is considered that the undervoltage is used for protection.

Design flaws, coils with circuit board protection, not adapted to high temperatures, frequent action environments, serious design flaws!

The coil voltage is different.

Generally, the coils of different voltages of the same brand of contactor can be interchanged.

But the model should be the same.

AC contactors are not available at 24V. You use a 24V intermediate relay to control the AC contactor, but the contact life of ordinary intermediate relay is generally not long, if you need a long-life intermediate relay, you can contact me.

The landlord asked how much current the contactor coil was, not the coil voltage, nor the contact current.

The coil current is on the manual, and some without the current give the power. For example, I have a manual in my hand, which is Delixi CJX2-0910 contactor, which says that the coil power is 9. It means 9w when it is attached, and when it is held.

According to Ohm's law, p=ui cos calculates a current of about 40-50 mA. Very small.

Current: 40-50mA

AC contactors are widely used as interrupting and control circuits for electricity. It uses the main contact to open and close the circuit, and the auxiliary contact to execute the control command. The main contact generally only has a normally open contact, while the auxiliary contact often has two pairs of normally open and normally closed contacts, 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 electrical conductivity and high temperature ablation resistance.

The operating current of the 24V AC contactor (coil AC24V) is less. Can be controlled with a reed switch.

There should be a rectifier, standard suppressor, in layman's terms, it plays the role of AC to DC, high current absorption, and small current retention, please note that the DC coil is used, and the internal rectification is mainly a wide voltage range.

Average power consumption of DC24V intermediate relays.

AC220V AC contactor start: 70VA, hold: 26 (the above is the power consumption of the contactor coil below 95A).
