Nextgen Power Controls designs and builds LT panels (low tension control panels) for factories, commercial buildings, hospitals, and infrastructure projects. Every panel is engineered from your single line diagram (SLD), assembled in our Odhav, Ahmedabad works, and tested before dispatch. We have built LT panels since 2014 for clients across Gujarat and India, and have exported them to Bangladesh, Nepal, Saudi Arabia, Qatar, and Canada. Ratings go from small 63 A distribution panels up to 5000 A main LT panels with ACB incomers.
An LT panel (low tension panel) is an electrical switchboard that receives power at low voltage, usually 415 V, 3-phase, 50 Hz, and distributes it safely to motors, machines, lighting, and sub-distribution boards. "Low tension" means the system runs below 1,000 V AC. Anything above that, such as 11 kV or 33 kV, is handled by an HT panel. In a typical plant, power arrives from the utility at 11 kV, passes through the HT panel and transformer, and is stepped down to 415 V. The LT panel is the next stop. It houses the main incomer breaker, copper or aluminum busbars, outgoing feeder breakers, metering, and protection relays. It protects every downstream circuit from overload, short circuit, and earth faults.
Additional features may include top or bottom cable termination, APFC integration, DG incomer with AMF functionality, non-essential feeder cut-off during mains failure and provisions for connecting bus ducts at the main incomer side. LT Panels deliver efficient power distribution, enhanced electrical safety, low power consumption and cost-effective performance.

FAQ
Frequently Ask Questions
An LT panel is a low tension electrical switchboard that receives power at up to 1,000 V AC, usually 415 V, and distributes it to motors, machines, and lighting circuits while protecting them from overload and short circuits.
An LT panel works below 1,000 V AC typically 415 V and uses ACBs, MCCBs, and MCBs. An HT panel works above 1,000 V, such as 11 kV or 33 kV, and uses VCBs or SF6 breakers. HT panels sit before the transformer and LT panels after it.
A basic LT distribution panel starts from about ₹40,000. Main LT panels with ACB incomers usually cost ₹1,50,000 to ₹5,00,000 or more, depending on current rating, feeders, and component brands.
Most LT panels are delivered in 3 to 5 weeks after drawing approval. Larger PCC and MCC panels can take 6 to 8 weeks.
Our LT panels are designed and tested to IEC 61439-1 and IEC 61439-2 confirm, with IP42 to IP55 enclosures depending on the site.
Yes. We supply, install, test, and commission LT panels on site and offer annual maintenance contracts after handover.
