A three-phase reactor does not have one reliable market price because current, voltage, impedance, construction, enclosure, and supply scope change the product being quoted. By the end, you will know how to define the reactor position, compare 3% and 5% options, request a like-for-like Pune quotation, and check the equipment before commissioning.
Key takeaways
- Request a quote only after specifying voltage, current, frequency, inductance, and reactor position.
- Choose a line or load reactor based on where protection is required.
- Compare 3% and 5% impedance against voltage drop and harmonic performance.
- Verify the nameplate, test documents, terminals, enclosure, and warranty before acceptance.
What determines a three-phase reactor price in Kasba Peth?
A defensible three phase reactor price in Kasba Peth cannot be stated without an electrical specification. The quotation changes with each of these technical inputs:
- Line-to-line voltage and rated continuous current
- 50 Hz frequency and inductance in millihenries
- 3% or 5% impedance
- Copper or aluminium winding
- Insulation class and permitted temperature rise
- Cooling method and mounting arrangement
- Enclosure, terminal configuration, and quantity
Confirm whether the price covers one complete three-phase assembly or three separate single-phase reactors. These are different supply scopes, even when their electrical ratings appear similar.
Also ask what the quotation includes:
- GST
- Freight and unloading
- Installation and interconnection hardware
- Testing and panel modification
A lower ex-works figure can cost more after delivery, handling, installation, and panel work are added. Compare the delivered scope, not just the first number.
For a reliable comparison, match line-to-line voltage, current, impedance, frequency, enclosure, and supply scope across every offer. Catalogue prices alone are misleading because a standard open-frame reactor and a protected, panel-mounted assembly are not equivalent products. This method gives you a meaningful three phase reactor price in Kasba Peth rather than an unqualified catalogue figure.
Which reactor position and electrical load are you specifying?
Specify the reactor’s wiring position and actual continuous RMS load before asking for a price. A supplier must know whether it is upstream or downstream of a variable-frequency drive.
| Position | What it means | Confirm before ordering |
|---|---|---|
| Input-side line reactor | Installed before the VFD to limit input transients and distortion | Drive input rating and supply conditions |
| Load or motor-side reactor | Installed between the VFD and motor to protect the cable and motor circuit | Drive output, cable length, motor insulation, and switching conditions |
| DC-link choke | Fitted in the drive’s DC bus, not the AC input or motor circuit | Drive manufacturer’s specified choke |
| Other application reactor | Used with a soft starter, rectifier, capacitor bank, or another harmonic-producing load | Load type and connection diagram |
Record these details in the RFQ:
- Equipment manufacturer and model
- Input voltage, input current, and intended 50 Hz frequency
- Motor kW, actual continuous RMS current, and overload duty
- Overload current and duration
- Ambient temperature and enclosure ventilation
- Upstream short-circuit conditions
- Reactor position: upstream or downstream of the drive
Motor horsepower alone is not enough. Drive input current, heat, restricted ventilation, and overload operation can make a nominal motor-size match inadequate. If you search “buy three phase reactor pune”, state 50 Hz on the purchase order when that is the intended Indian supply frequency.
A reactor offered as a substitute must have its application and wiring position confirmed in writing.
How do 3% and 5% reactors affect performance and price?
A 5% reactor usually limits input-current transients and distortion more effectively than a 3% reactor. It also causes greater voltage drop, reducing the drive’s available input-voltage margin; select 5% only after checking the drive manufacturer’s permitted impedance and the installation calculation.
A 5% design can cost more because it may require greater inductance, winding material, or thermal capacity, but the percentage alone does not justify the premium. The phrase three phase line reactor price pune describes no fixed figure until the electrical specification is complete.
Inductive reactance follows Xₗ = 2πfL, so the required millihenry value depends on frequency. A reactor rated at 50 Hz cannot be assumed to provide the same impedance at another frequency. State 50 Hz on the purchase order for an Indian supply.
Use this quotation checklist:
- Match line-to-line voltage, rated amps, frequency, mH value, percent impedance, and short-time current.
- Check insulation class, temperature rise, dielectric withstand, losses, dimensions, cooling method, and terminal arrangement.
- Confirm whether the quoted price covers one three-phase assembly or three separate single-phase reactors.
- Ask whether GST, freight, unloading, installation, testing, and panel modification are included.
- Treat a 3% or 5% reactor as current-spike mitigation, not complete harmonic correction. Strict site limits may require a tuned or detuned filter or an active harmonic filter.
A lower percentage can preserve voltage margin and cost less; a higher percentage can provide stronger impedance. The correct choice is the one the drive and installation can tolerate.
How can you buy from a three-phase reactor supplier in Kasba Peth?
Send a written RFQ to a three-phase reactor supplier in Kasba Peth; verbal descriptions such as “three-phase choke for a VFD” invite mismatched quotations.
Include these fields:
- System voltage and 50 Hz frequency
- Continuous current
- Overload current and duration
- Target impedance: 3% or 5%
- Required inductance in millihenries
- VFD input-side, motor-side, or other load position
- Ambient temperature and upstream short-circuit environment
- Enclosure or IP requirement
- Terminal arrangement and quantity
Ask the supplier to identify the commercial status clearly.
| Supply status | What it means | Ask for |
|---|---|---|
| Ex-stock | Ready for dispatch from current inventory | Stock confirmation, pickup point, and dispatch date |
| Made to order | Built after your order is accepted | Manufacturing lead time and approval drawing |
| Assembled after confirmation | Components or enclosure are configured for your application | Final scope, assembly time, and inspection details |
An industrial reactor distributor in Kasba Peth may quote an open-frame component, while your panel may need a ventilated enclosure, finger-safe terminals, IP protection, or a complete panel-mounted assembly. Request each as a separate line item, not as an assumed inclusion.
Also request the lead time, pickup point, Pune delivery option, freight charge, and unloading responsibility. Deeva Electricals and Automation can be approached with this RFQ, but compare its datasheet, supply scope, and delivery terms with other offers rather than choosing on location alone.

What should you verify before accepting the reactor?
Accept the reactor only after the delivered unit matches the purchase order, not merely the supplier’s generic description. A product labelled “three-phase choke” is insufficient for acceptance.
Request a datasheet and nameplate sample confirming:
- Rated voltage, continuous current, 50 Hz frequency, and inductance in mH or percentage impedance
- Insulation class, temperature rise, dielectric withstand, and losses
- Dimensions, cooling method, phase-terminal markings, enclosure, and mounting arrangement
Separate the reactor price from GST, freight, unloading, installation, interconnection hardware, testing, and panel changes before comparing the three phase line reactor price Pune. A low ex-works quote can become the costlier delivered option.
| Stage | Verify | Resolve before acceptance |
|---|---|---|
| Receipt | Purchase-order voltage and current, nameplate, phase terminals, enclosure, and physical condition | Reject or quarantine any mismatch, damaged winding, unclear marking, or missing enclosure |
| Testing | Phase-to-phase inductance or impedance consistency, insulation resistance, and dielectric withstand | Follow the approved test procedure and investigate failed or unbalanced readings |
| Commissioning | Audible hum and temperature after the actual load reaches operating conditions | Check overload, restricted ventilation, or unsuitable design if heating is excessive |
Record the final measurements, wiring position, datasheet, and test report. Keep them with the panel documentation so maintenance personnel can identify the reactor and repeat the acceptance checks.
