CR — Current Reset

Sales and Ordering Information

or by email at CSR@eosmfg.com

Current Reset (CR) Fault Indicators can be installed on both underground and overhead systems. CRs are powered by the load current present on an energized line. A CR indicator will respond to a fault and remain in the faulted-display condition until the line is energized with normal line load at which time it will automatically reset. For underground applications, three-phase versions are available with integral and remote displays.

 

UV-stabilized housings, stainless-steel and vinyl-coated clamping mechanisms make CR Fault Indicators suitable for use in the harsh environments of overhead and underground applications.

RadioRANGER Compatible

  • Automatic reset upon restoration of load current.

  • Closed-core design provides adjacent phase immunity.

  • Available for single- and three-phase applications.

  • Choose from BEACON® LED, target, and combination displays, depending on your application and operating practices.

  • Ideal for installation in pad-mounted equipment without elbow testpoints; install the fault indicator outside of the influence of the ground return path of the cable’s concentric neutral.

  • Installation on low-voltage secondary lines is an ideal fault-finding solution in industrial environments.

  • Choose the auxiliary contact option for SCADA compatibility.

  • Fault-powered current reset models also available for low-load current applications. Please consult SEL.
