Allen-Bradley 193-EIOGP-42-24D E300 Relay Control Module With PTC, 267 to 725 mA, 4NO-2NC Contact Form, 24 VDC Coil
In isolated or high impedance grounded systems, core balanced current sensors are typically used to detect low level ground faults caused by insulation breakdowns or entry of foreign objects. Detection of such ground faults can be used to interrupt the system to prevent further damage or to alert the appropriate personnel to perform timely maintenance. The E300 relay provides core balanced ground fault current detection capability, with the option of enabling ground fault trip, ground fault warning or both. The ground fault detection method and range depends upon the catalog number of the E300 sensing module and control module ordered.
