Large Split Core Over 500A
Current Transformers
These large split core current transformers are used for circuits over 500A.
This series of custom large split core current transformers (“SP”) are simple and designed for connections to the WebMeter products from CircuitMeter.
These have specified window sizes to fit various busbar equipment. Installing these CTs may not require a shutdown of the circuit involved. Split core current transformers may minimize shutdown time.
Installation must be installed by a certified electrician and adhere to local electrical safety guidelines.
