Revenue Grade Current Sensor – SCT-075H by Magnelab

50-200 Aac input : 333 mVac output. 0.75″ opening. +/- 0.5% linearity, phase angle +/- 0.25%

Product Description

Magnelab’s SCT-075H is a revenue grade current sensor meeting ANSI class C57.13 0.6 with unprecedented linearity and superior phase angle up to 200 Amps passing through the center conductor.

The SCT-075H is a revenue grade current sensor with a 0.75″ opening.  It transforms an AC input current up to 200A to an output of 0.333 Volts. The SCT-075H is available in the following amperages: 50A, 100A, and 200A.  Like the SCT-0750, the SCT-075H has no hinges to break, making it durable. It’s unique opening mechanism has a self-locking mechanism and allows for easy installation around conductors.  This makes retrofitting existing installations simple.

The SCT-075H has a phase angle <= 0.25° and accuracy +/- 0.5% from 10% to 120% of the rated input current.

Frequent Applications

  • Sub-metering
  • Tenant billing
  • Cost allocation
  • Precision Power Monitoring

Unsure if you need a revenue grade current sensor?  Revenue grade accuracy is needed for sub-metering applications and other times where precision is essential. The SCT-0750 is Magnelab’s standard accuracy version of the SCT-075H.

When using revenue grade current sensors be sure when buying a meter to find an ANSI C12.20 Class 0.5S or better meter. The system is only as good as the weakest component!

Compatible power meters accept a voltage input.  Look for meters on our website that start with this symbol:
