JSL Industries is a small, decades-old Indian engineering firm that designs and makes the electrical equipment that controls and protects power systems - from the high-voltage transformers in transmission grids to the motor starters on factory floors. Incorporated in 1966 and operating from a single factory in Mogar, Gujarat, the company has spent over fifty years quietly building a catalogue of indigenously developed products, all certified to Indian and international standards. The recurring approach is self-reliant engineering: it designs in-house, tests to the latest standards, and sells to utilities and industries that need equipment built to last, not bought off the shelf. # Business segments A single-engine manufacturer with three product divisions - instrument transformers for the grid, switchgear for industrial power control, and motors and pumps for efficient drive - all sharing one factory, one set of testing labs, and one fifty-year reputation for indigenous design. ## 1. Instrument transformers: the high-voltage sensing business **The division makes the specialised transformers that measure current and voltage on transmission lines up to 66 kV, selling primarily to state electricity utilities that order in bulk.** - **Senses the grid** - Instrument transformers step down high voltage and current to levels that meters and protective relays can read safely; without them, a substation is blind. The division makes both current transformers (CTs) and potential transformers (PTs) for indoor and outdoor use, including units for railway electrification at 25 kV. - **Built to customer specification** - Every order is configured for the number of cores and accuracy class the client needs, rather than sold as a standard off-the-shelf item. This means the division competes on engineering capability, not just price. - **An accredited test lab is the differentiator** - The in-house instrument transformer laboratory holds NABL accreditation, recently extended to cover testing from 25A to 1200A, valid for four years. That accreditation lets the company self-certify product performance, which matters when bidding for utility tenders. - **Utility orders are lumpy but large** - The division wins contracts from state transmission companies like Gujarat’s GETCO. In FY26 it shipped 3,861 units of 66 kV instrument transformers, and recent orders include a Rs. 12.50 crore (including GST) contract for 66 kV CTs and PTs booked in February 2025. - **R&D keeps the catalogue tender-ready** - Recent development work included type-testing an 11 kV oil-cooled outdoor CT metering unit to the IS 16227 / IEC 61869-2 standard, specifically to meet client requirements and qualify for new tenders. ## 2. Switchgear: the factory-floor power controller **The division makes the low-tension equipment - starters, breakers, contactors, and panels - that switches, protects and controls motors and electrical circuits in industrial plants.** - **Starts and stops heavy motors** - The core product line is motor starters: oil-immersed direct-on-line, star-delta and auto-transformer starters that handle the surge of current when a large motor kicks in. These are not commodity switches; they are engineered for specific horsepower ratings, with recent R&D extending the oil-immersed star-delta range up to 60 HP. - **Protects the circuit when things go wrong** - The division also makes air circuit breakers (ACBs) and moulded-case circuit breakers (MCCBs) that interrupt fault currents before they damage equipment. The ACB range has been re-certified to the latest IS/IEC 60947-2 standard, which keeps the products valid for industrial buyers who require compliance. - **Assembles the full control suite** - Beyond individual devices, the division builds the panels and enclosures that house them: motor control centres, distribution boards, APFC (automatic power factor correction) panels, and bus-ducts. This turns a catalogue of components into a complete power-management solution for a factory or a building. - **Standards-driven re-engineering** - When Indian standards change, the division re-tests and re-designs. It has certified its 200 kVA and 500 kVA LT distribution boards to the new IS/IEC 61439 standard and modified the 200 kVA box design to match, ensuring the product stays sellable without a gap. ## 3. Motors and pumps: the efficient drive business **The division makes energy-efficient electric motors and the mono-block pumps that package a motor and pump into a single unit, targeting buyers who care about power bills and regulatory efficiency norms.** - **Efficiency is the product** - The division has developed motors that meet IE4 (super-premium) efficiency class, well ahead of the mandatory minimums in India. Recent R&D delivered a TEFC foot-mounted induction motor with IE4 efficiency for 4-pole series up to the 315 frame and for 2-pole up to the 200 frame. - **Three motor families for different jobs** - The range spans TEFC (totally enclosed, fan-cooled) motors for dusty or wet environments, SPDP (screen-protected, drip-proof) motors for cleaner indoor use, and VHS (vertical hollow shaft) motors designed to drive deep-well pumps. Each is built to IS/IEC 60034-1 standards. - **Motors and pumps under one roof** - The division also makes uni-built mono-block pumps and submersible pump controllers, so a customer buying a pump gets a motor that was designed to work with it, not a generic motor adapted after the fact. - **A shared testing backbone** - The company has a full-load testing facility that can handle both horizontal and vertical motors, a capability it shares with its promoter-group company Jyoti Limited. That means motors can be proven at full rated load before they leave the factory. # Group structure and partners **JSL Industries is a standalone company with no subsidiaries, but it operates inside a tight promoter-group ecosystem - sharing a brand, a test facility, and cross-shareholdings with Jyoti Limited, a fellow electrical-equipment manufacturer.** - **No subsidiaries, no joint ventures** - The company is a single legal entity with a single factory and 47 employees as of March 2026. There is no holding-company complexity. - **Cross-held with Jyoti Limited** - JSL owns 4.65% directly and 19.30% indirectly in Jyoti Limited; Jyoti owns 2.49% directly and 8.40% indirectly in JSL. The two companies are physically close, which makes coordination, inspection and follow-up straightforward. - **Jyoti is both a supplier and a customer** - JSL sells starters, motors, instrument transformers and control panels to Jyoti, buys job-work and silver-plating services from it, and pays a royalty to use the Jyoti brand name and trademark. The shared full-load motor testing facility is a practical example of the operational overlap. - **A family-run board** - The five-member board includes Rahul Amin as non-executive chairman and his wife Tejal Amin as whole-time director, alongside a CEO, CFO and company secretary in the key management roles.
