Product Description

The Magnelab High Quality Current Transformer RCT-100T flexible Rogowski CT current sensor measures AC current up to 5,000 Amps. The flexible coil opens at the connector junction and can be installed on an existing cable or buss-bar in a matter of seconds. This “Tear-drop” style design facilitates installations with limited
electrical panel space. Electrical performance is equal to our standard
RCT-1800-XXX Series.

The RCT-100T-XXX Rogowski coil series can measure as low as 25A and as high as 5000A with 1% accuracy. Be sure to ask a sales person for the right integrator when purchasing, based on your measuring needs.

Note: The integrator requires a power supply of 12 to 30V AC or DC, which is not included. You may
purchase one here.The RCT-100T series Rogowski coil can be ordered WITHOUT the integrator when being used with Measurlogic and eGauge power meters.
