Power interruptions are unpredictable—but with Selfguard’s Changeover Switch, you stay prepared. A Changeover Switch enables quick and automatic transfer of electrical load between the main supply and the backup generator, ensuring that your operations never come to a halt.

Selfguard’s Changeover Switches are designed to deliver unmatched reliability and safety. Built with advanced engineering and high-quality materials, they offer fast response and smooth switching, preventing voltage fluctuations and protecting sensitive equipment.

Available in both manual and automatic versions, Selfguard Changeover Switches are perfect for residential, commercial, and industrial applications. Whether you run a small business, a hospital, or a factory, this system ensures power continuity without manual effort.

These switches are compact, easy to install, and built for long-lasting performance. The sturdy design withstands demanding environments, while its user-friendly features make it ideal for daily use.

An Automatic Transfer Switch (ATS) is an essential component in modern power backup systems. It automatically transfers the electrical load from the main power supply to a generator or alternate source during a power failure—and switches it back once the main supply is restored. This ensures uninterrupted power for homes, commercial buildings, hospitals, and industries.

How Does an Automatic Transfer Switch Work?

The ATS continuously monitors the utility power. When it detects an outage or voltage drop, it sends a signal to start the generator and switches the load to the backup power source. Once the utility power stabilizes, the ATS switches the load back and stops the generator automatically.

This entire operation is fully automated, which eliminates the need for manual switching, reducing downtime and risk.

Benefits of Using an ATS:

Uninterrupted power supply during outages

Fully automatic operation – no manual input needed

Protects equipment from voltage fluctuations and outages

Improves safety in critical environments like hospitals and data centers

Integrates easily with diesel, petrol, and inverter generators

Selfguard ATS Solutions

At Selfguard, we offer robust and reliable Automatic Transfer Switch panels designed for residential, commercial, and industrial applications. Our ATS panels are compatible with generators of all major brands, including Honda, Kirloskar, Mahindra, and Cummins. They are built with high-quality contactors, intelligent controllers, and safety interlocks for long-lasting performance.

Whether you are setting up a silent generator backup for your home or a high-load industrial power solution, our ATS panels ensure smooth, safe, and automatic changeover every time.

A three phase sequence corrector plays a vital role in electrical safety and equipment longevity. In any three-phase power system, maintaining the correct sequence (R-Y-B) is critical for the correct operation of motors, pumps, and HVAC systems. A wrong sequence can cause reverse rotation, mechanical wear, and operational inefficiency.

This device continuously monitors the incoming phase sequence and either alerts the user or prevents operation until the correct sequence is established. Some models even correct the sequence automatically, ensuring plug-and-play protection without manual intervention.

Industries that rely on critical machinery—such as CNC machines, elevators, escalators, and compressors—cannot afford phase sequence errors. Integrating a three phase sequence corrector ensures operational consistency and protects against downtime and maintenance costs.

Selfguard’s range of sequence correctors offers reliable performance, compact design, and long-term durability. Whether you're installing a new generator panel or upgrading your electrical safety setup, incorporating this device is a smart choice.
