Why Choose Subtech
Every Subtech panel is designed to survive India's harshest conditions. From scorching summers to monsoon humidity, our technology keeps motors running when others fail.
Industry-first warranty on PMC coils. We stand behind our engineering. If the coil burns, we replace it. No questions asked.
Our MPU (Motor Protection Unit) uses microprocessor technology for precise detection of single phasing, dry run, overload, and voltage fluctuation.
Pre-wired and tested panels reduce installation time by 60%. Plug-and-play simplicity for electricians in the field.
Live monitoring of Voltage, Amperes, Run-Hours, and fault codes. 90% of issues diagnosed over phone without site visit.
From PCB design to final assembly, everything happens under one roof in Greater Noida. Complete quality control at every step.
While the industry still relies on conventional contactors and disconnected protection components, Subtech has developed two proprietary technologies: MPU and PMC, that replace multiple outdated parts with smarter, integrated solutions. This is not an upgrade. This is a different class of motor control.

A microcontroller-based digital unit developed by Subtech that consolidates monitoring, protection, and control into a single intelligent module, replacing what used to require five separate components.

A modified contactor concept engineered by Subtech that eliminates the two most common failure modes in conventional contactors: coil burning and contact chattering, through powerless, fast switching on a wide DC voltage range.
Microprocessor-based protection. Works in any weather.
DC-operated. No humming. 5-year coil warranty.
Detects single-phasing on BOTH input and output side.
Live Amperes, Voltage, Run-Hours. 90% issues resolved by phone.
From 0.5 HP to 500 HP. From farms to power plants.

Since 1998, we have been manufacturing reliable electrical control panels, motor starters, AMF systems, and pump automation solutions from our facility in Greater Noida. Over 5,00,000 panels installed across government, industrial, and agricultural projects pan-India.
