GT1224

The GT1224 from Schneider Electric, part of the Square D series, functions as a ground fault sensor current transformer that plays a crucial role in electrical distribution applications. It is designed for use in both main and feeder circuits, ensuring effective monitoring of current flow. The model supports a nominal voltage of 120 VAC and can accommodate a wide voltage range from 100 V up to 600 VAC, making it versatile for various electrical installations.

This current transformer operates within a frequency of either 50 or 60 Hz. With a current rating that spans from 100 A to 1200 A, the GT1224 is capable and adaptable for different operational requirements. Notably, it features a precise current ratio of 25.00069444, facilitating accurate measurements.

In terms of environmental resilience, the device is built to operate efficiently across a temperature spectrum from -40°C to +85°C, making it suitable for diverse conditions. The weight of the transformer is approximately 1.2 kg, and it is housed within a rectangular open frame design. Protection class of IP20 ensures that it is safeguarded against solid objects but is not rated for exposure to water.

Additionally, the GT1224 includes a shunt trip functionality operating at 120 VAC for 50/60 Hz applications, enhancing its safety features and allowing for prompt disconnection during fault conditions. Compliance with UL and CE standards reinforces its reliability, ensuring adherence to protective and safety regulations in electrical systems.
