Low-Voltage Current Transformers / Extended Range Current Transformers (ERCTs) for Billing
About the Product
Current Transformers ROS Series, designed for billing purposes and suited to power systems of 600-voltage or below, offer revenue metering of at least a Class 0.3 Accuracy and can be used for indoor application or in an outdoor enclosure. For ROS-38/50/65/80 products, insulation for the coil is provided by thermoplastic rubber, while ROS-38A/66A/78A models are resin-insulated. In each model, the secondary side of the CT is equipped with a short-circuiting device, while the included terminal cover is sealable. Various window diameters and current ratios are available. Furthermore, ROS-66A/78A can be offered as Extended Range Current Transformers (ERCTs) upon request.
For many years, the ROS Series products have been provided to power companies in numerous countries. Characterized by the stability of their quality and performance, these current transformers have met with consistent customer approval.
