The CS11 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 CS11 is external to the wire jacket and has no direct electrical connection to the system.
The CS11 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.

Connect the red wire to ground rather than its normal location on the CR200(X).
No. The CS11-L is an ac-only sensor.
Yes. Three CS11-L sensors can be connected to a data logger to measure the amperage on each of three phases.
Not directly. If the CS11-L is connected to a data logger, the data logger can take the ac measurement and control a solid-state relay based on some threshold within the data logger program. The solid-state relay can then control other relays, solenoids, or motor starters. (Use of a solid-state relay is preferred because the data logger can trigger it with a small 5 Vdc mA signal.)
The following are some of the features of the CS11-L:
