Product Code : SCL-EAE-12046
Electrical Inductor Load Bank 2.4 kVAR (SKU SCL-EAE-12046) is a three-phase reactive load bank that adds lagging current in four balanced steps of 0.6 kVAR, up to 2.4 kVAR at 415 V. It is built for engineering students and technicians analysing alternator regulation, transformer loading and power factor correction. Science Lab Supplies makes it in-house: the bank is manufactured at Plot 448, HSIIDC Industrial Area, Saha, Ambala, India, and sold directly to colleges, training institutes, tender contractors and distributors.

Applications and Experiments for the 2.4 kVAR Inductor Load Bank
The bank gives a measured, balanced lagging load so students can follow how reactive current affects voltage, current and power factor in a three-phase circuit. It belongs in electrical machines and power-systems practicals for B.Tech, diploma and higher vocational courses, where 0.6 kVAR steps make each reading easy to compare.
- Alternator work: applying lagging loads to an educational alternator to plot excitation curves and vector diagrams.
- Power factor correction: pairing the bank with the Laboratory Capacitive Loading Unit 1.2 kVAR to show reactive compensation.
- Transformer loading: drawing reactive current from secondary windings on the Transformer Trainer to study regulation.
Never unplug a lead with a step ON, as an interrupted inductive current can arc. Supervised use only.
Standard Scope of Supply
The bank is supplied with six high-current insulated patch cords fitted with 4 mm safety banana plugs, three removable phase bridging copper links and an English operations manual containing circuit diagrams and formulas. The three-phase source and measuring meters are separate and can be quoted on request.
Packing, MOQ and Lead Time
Request a quotation for one bank or for a matched group of reactive loads for several benches. Science Lab Supplies sets out the packing, delivery time and price for that quantity, and resistive or capacitive banks from its range of physics lab equipment in India can share the same quotation.
With its Importer-Exporter Code, Science Lab Supplies is in a position to ship to buyers in Zambia, Rwanda, South Africa, Qatar, Sri Lanka and Vietnam. Prices can be requested through the contact page or by adding items to the enquiry cart; the lab tender page explains tender support.
Frequently Asked Questions
Can the bank be used for single-phase loading?
Yes. Each phase is brought out separately on the front terminal panel, so one coil branch can be isolated and used for 220–240 V single-phase tests while the others stay disconnected.
How are the load steps arranged?
There are four balanced steps of 0.6 kVAR each, giving 0.6, 1.2, 1.8 or 2.4 kVAR of lagging load shared equally across the three phases.
What protects users and coils during use?
Varistor circuitry absorbs inductive switching surges, each phase has independent branch protection that trips on overcurrent, and the steel chassis is bonded to an internal safety earth line.
Who makes the 2.4 kVAR inductor bank?
Science Lab Supplies, a laboratory equipment manufacturer in India, makes it at its factory in Saha, Ambala, India. Being the manufacturer, it prices each order directly, with no reseller margin added between the factory and the buyer.
