GDSM-125-4P Automatic Transfer Switch Overview

Şu GDSM-125-4P automatic transfer switch is a moulded-case dual power transfer switch designed for AC power systems requiring controlled changeover between normal and standby power sources. As a CB-class automatic transfer switch, it combines dual-power switching with a robust moulded-case structure suitable for commercial, industrial and equipment-control applications.

The GDSM-125-4P uses a 125A shell frame and provides rated current options of 25A, 32A, 40A, 50A, 63A, 80A, 100A and 125A. The 4-pole configuration allows switching of three phase conductors together with the neutral conductor, making it suitable for three-phase four-wire electrical systems.

Rated operating voltage is AC400V 50Hz, while the rated insulation voltage reaches AC800V. An 8 kV darbe dayanım gerilimi provides additional insulation capability for demanding low-voltage distribution environments.

Şu GDSM-125-4P automatic transfer switch supports both automatic and manual operation. Front-panel indicators provide visual information for power and switch operating states, helping installers and maintenance personnel identify the status of normal and standby sources.

With a rated switching time of approximately 0.3 seconds, the GDSM-125-4P provides fast changeover for applications where continued electrical supply is important.
