GLD 100A to 3200A Automatic Transfer Switch

The GLD series automatic transfer switch device integrates switching and logic control into one unit, eliminating the need for an external controller and enabling electromechanical integration. It features voltage detection, frequency detection, communication interface, fire feedback, and electrical and mechanical interlock functions, allowing for automatic, electric remote, and emergency manual control.

The operation is managed by a logic control board that executes various logic commands to control the motor and gearbox operations. The motor drives the switch spring energy storage and instant release acceleration mechanism, enabling rapid circuit connection, disconnection, or conversion. This is achieved through a clearly visible state for safe isolation, significantly enhancing electrical and mechanical performance.

Switches rated below 100A are designed with a compact and sturdy metal casing. For switches rated above 100A, the control part is housed in a metal casing and offers both automatic and electric control modes. The switch part is made with an unsaturated polyester glass fiber reinforced molded plastic casing, providing strong dielectric performance, protection capability, and reliable operational safety.

The switch is suitable for automatic transfer between the main power supply and backup power supply in power systems, or for automatic transfer and safe isolation between two load devices. The switch is aesthetically pleasing, simple, and compact in size.
