The ELCON 400A 4 Pole On Load Changeover Switch is a heavy-duty manual on load changeover switch designed for safe power transfer in three-phase electrical systems. Rated at 400 Amperes, this on load changeover switch 400A enables switching between the main utility supply and an alternate source such as a generator. Built in compliance with IS/IEC 60947-3, it ensures reliable performance, electrical safety, and long-term durability in industrial and commercial environments.

The ELCON 400A changeover switch features a robust construction that supports high-current operations under continuous load conditions. As a 4 pole on load changeover switch, it includes three phases and a neutral, ensuring complete isolation and balanced power transfer. This three phase on load changeover switch is widely used in LT panels, manufacturing plants, factories, and infrastructure projects where power supply is essential. The heavy-duty design makes it an ideal industrial on load changeover switch for demanding electrical installations.
The manual on load changeover switch 400A is equipped with a positive mechanical interlocking system that prevents accidental interconnection of two power sources. It operates through three defined positions—I (Main Supply), O (OFF), and II (Generator Supply)—ensuring safe and controlled switching. The ELCON on load changeover switch uses high-quality silver alloy contacts and a quick-make, quick-break mechanism to reduce arcing and improve operational life. This makes it a reliable main and generator changeover switch 400A for high-capacity electrical systems.
