Commonly known as three-phase reactors or inductors, a three-phase line choke, or 3 PH line choke, serves as a distinct line choke for electrical systems. Three windings based on conductors are included to facilitate three-phase operation. This device consists of two conductors merged with one neutral conductor, which is protected by insulation. The two conductors are linked by two switches when the line is active, while these switches remain open when the line is inactive. Our valued clients can access CN-approved chokes from our range of products since we are producers of three-phase line chokes.
Types of 3 Phase Line Choke:
Serve as 3 phase line choke suppliers in Sharjah, we offer it with various kinds to make variety of choices for the customers.
- Air Core 3 Phase Line Choke: These chokes substitute air for their core material, thus eliminating the need for ferromagnetic substances, including iron and ferrite. Air core chokes find use in systems needing lower inductance measurements along with higher current consumption. Their linear inductance behavior maintains a steady inductance value across current variations. Iron core chokes have superior resistance to saturation effects, but air core chokes find increased usage in applications requiring high peak currents or demanding linear characteristics. These devices find extensive use when safeguarding VFDs as well as filtering harmonics.
- Iron Core 3 Phase Line Choke: These chokes leverage laminated iron cores to build their inductance to higher values across a smaller size compared to conventional air core chokes. The application of iron core chokes proves optimal for systems requiring elevated inductance values in harmonic filtering systems and power factor correction needs. Higher current reaching iron core saturation diminishes the operational efficiency of chokes. Moving forward, such chokes demonstrate superior price efficiency compared to equivalent inductance systems based on air core chokes.
- Reactor/Inductor or 3 phase line choke for VFD Input: We build specialized "reactors" or "inductors" exclusively for VFD input usage. The VFD suffers from protection that counteracts voltage spikes and surges along with power line harmonics. By utilizing this type of choke, the harmonic currents from VFD operation become minimized, which ultimately increases overall power quality. Alternative names for VFD input reactors/inductors exist because they protect VFDs from failing while also conserving delicate electronic components within the system.
- Reactor/Inductor or 3 Phase line choke for VFD Output (Load Reactor): The output section of VFDs contains these chokes, known as load reactors, which stabilize the motor's voltage reception. When VFDs generate pulsed voltage waveforms, they result in motor heating while also causing noise production and shortening motor lifespan. The application of load reactors helps reduce motor noise together with lower operating temperature while extending motor lifetime. Such devices provide significant benefits to motors operating slowly while needing longer cable runs.
- Harmonic Filter Reactor: We produce 3-phase line chokes or inductors specifically for capacitor applications as tuned harmonic filters. The designed filtering system uses select harmonic frequencies from electrical systems to establish a low-resistance path which diverts the harmonic currents from affecting devices and prevents equipment damage. The power quality in systems with non-linear loads depends heavily on the deployment of harmonic filter reactors.

Features of 3 Phase Line Choke:
We are 3 phase line choke suppliers in Sharjah and provide it with the following features.
- Reduces Harmonics: Stretches the current waveform, thus reducing harmonic distortions caused by nonlinear loads.
- Protects VFDs: Protects variable frequency drives from voltage spikes and surges.
- Improves Power Factor: Helps improve power factor, which in turn increases the efficiency of energy.
- Limits Current: Limits the rate of increase of the current (di/dt), thereby reducing stress on drive components.
- Reduces Motor Noise: On the output side, it smoothest the voltage to reduce motor noise and temperature.
- Filters EMI/RFI: Can remove electromagnetic and radio frequency interference.
- Different Core Types: Available with air cores (for linearity) or iron cores (for higher inductance).
- Various Designs: Available in configurations for VFD input, VFD output (load reactors), and harmonic filtering.
Applications of 3 Phase Line Choke:
As 3 phase line choke manufacturers in Sharjah, our chokes or inductors/reactors find in multiple electric systems for power quality and equipment protection. Below are some applications of it.
- Power Factor Correction: The line chokes, although not their primary use, may enhance power factor in cooperation with additional power factor correction devices.
- Motor Protection: When mounted on the output side of the VFD (acting as a load reactor), line chokes protect the motors against voltage surges and the pulsed voltage waveforms generated by the VFDs. This reduces heating, noise, and ultimately prolongs the life of the motor.
- Industrial Automation: Line chokes are applied in multiple industrial automation configurations for the improvement of power quality, protection of sensitive electronic equipment, and assurance of reliable operation.
- Renewable Energy Systems: In solar and wind energy setups, line chokes are put in place to eliminate harmonics from inverters and to protect them from grid disturbances.
- Commercial Buildings: Power quality problems can plague modern commercial buildings filled with electronic devices. Line chokes can help mitigate those problems and protect sensitive devices like computers and lighting systems.
- Data Centers: Data centers require a very highly reliable power supply. Line chokes can help protect servers and other IT equipment from power disturbances.
- Electric Vehicle (EV) Charging Points: The rise of EVs is parallel with the rise of charging stations. Line chokes would help in the reduction of harmonics produced by EV chargers and hence protect the grid.
