Product Description

Magnelab’s SCT-075R is a Revenue Grade AC Current Sensor with a 3/4″ opening.

The SCT-075R is a Revenue Grade AC Current Sensor that complies with ANSI C57.13 Class 0.6.  It is available in ratings up to 100 Amps, outputting 0.333 Volts. The following amperages are currently available: 50A and 100A.

Note that the SCT-075H is replacing the SCT-075R. The 200A and 250A versions of the SCT-075R are no longer available.

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-075R.

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:
