Benefits and Features

  • Ideal applications include motor or generator load conditions, efficiency studies, intermittent fault detection, and rough submetering
  • No direct electrical connection to the electrical system

The "-L" on a product model indicates that the cable length is specified at the time of order.


Detailed Description

The CS10 uses CR Magnetic's CR8459 Current Transformer to detect the ac current along an electrical wire using the magnetic field that is generated by that current. The CS10 is external to the wire jacket and has no direct electrical connection to the system.

The CS10 is recommended for measurements that do not require high accuracy, such as motor or generator load condition monitoring, efficiency studies, intermittent fault detection, and rough submetering.
