SUNGROW - CT- 300A (Clamp CT)

The SGR-CT-300 is a 300 A split-core current transformer for electrical current measurement and monitoring applications. Its split-core design allows installation around an existing conductor without disconnecting the cable, making it suitable for compatible metering, monitoring and energy management systems. SGR-CT-300 Data Sheet Key Features Split-core design for installation around existing conductors 100–300 A primary measurement range 24 mm aperture Class 1 accuracy 50/60 Hz operating frequency 0.66 kV insulation rating 3 kV isolation, Category II UL94 V-0 flame-retardant enclosure CE certified Technical Specifications Primary measurement range 100–300 A Aperture 24 mm Cable length 0.9 m Accuracy Class 1 Operating frequency 50/60 Hz Operating temperature -15°C to +45°C Overrange 1.2 × Ipn Insulation 0.66 kV Isolation 3 kV (Category II) Enclosure UL94 V-0 flame retardant Standards EN 60044-1:1999+A1:2000+A2:2003; EN 61869-1:2009; EN 61869-2:2012 Installation Notes Install the CT with the arrow on the moulded case pointing towards the load, away from the mains supply.
