Detailed Description:
Eaton / Cutler Hammer Transformer protection relay features eight programmable binary inputs and mass memory for data storage. An unrestrained differential element gives fast tripping on heavy internal faults to limit catastrophic damage to the transformer. It has instantaneous overcurrent elements that allow quick clearing of severe internal or external faults. Front-panel LCD display with background illumination, permits for wide-angle viewing in all light conditions. Maintenance mode increases safety by providing a simple and reliable method to minimize fault clearing time.
Single compact case offers complete protection as well as control and reduces panel space, wiring and costs. It has integral test function that reduces maintenance time and expense. Zone selective interlocking improves coordination and tripping time and saves money compared to a traditional bus differential scheme. Trip and event recording in non-volatile memory, gives detailed information for analysis and system restoration, reducing trouble shooting time and maintenance costs. It has voltage rating of 19 - 300 VDC/40 - 250 VAC and temperature rating of -40 to 140 degree Celsius. Relay is UL listed, CSA certified, ANSI certified and meets EN Standard.
