Protections CTs are designed to be used with protective and trip relays in order to open circuit breakers. These CTs can handle higher currents during fault conditions and this is determined by their class rating. The main types of protection CTs are; PVC tape wound, Class PS/X and resin cast.
Feel free to give us a call or email us with your specific requirements and we will be happy to custom build this CT for you.
