Product Description

The Magnelab 4 Inch Current Transducer RCT-1200 flexible RopeCT current sensor measures AC
current up to 5,000 Amps. The flexible Rogowski coil opens at the
connector junction and can be installed on an existing cable or buss-bar
in a matter of seconds. See our RCT-1200-000 if you would like a Rogowski coil without an integrator (which will output 70 mV per 1000A).
You may also be interested in the new RCT-100T, RCT-150T, RCT-350T, RCT-600T and RCT-900T series Rogowski coils,
which allow for use in smaller, tighter situations. These “tear drop”
Rogowski coils are available with or without an integrator.

RCT-1200-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-1800 series Rogowski coil can be ordered WITHOUT the integrator when being used with Measurlogic and eGauge power meters.
