Power protection relay A Line

flush-mountmodularelectronic

The series of electronic analogic protective relays herebelow presented has been designed according to the most advanced technologies in order to obtain the highest reliability, accuracy and immunity to interference and is made with first choice components safely dimensioned and protected. The application of severe testing and quality control procedures guarantees the reliability of the product. Measuring inputs supplied through internal adaptor transformers Multivoltage a.c. and d.c. autoranging power supply unit Draw-out modular execution on standard european size P.C. boards Fibreglass reinforced epoxy resin P.C. boards with tinplated copper tracks, solder mask special silicon humidity protection and screen printed component designators P.C. board connectors with golden plated pins rated 10A continuous and 200A 1sec “E” For flush mounting with back connection terminals, draw-out relay boards with automatic short circuiting of the current inputs. Transparent front cover. Protection degree IP54; accessories for surface mounting (E/I) are also available. “E/R” Standard 19”3U (8 modules) or 6U (16 modules) rack with back connection terminals, draw-out relay boards with short circuiting of the current. Output Relays Two versions are provided: Standard version: the output relays are deenergized on normal operating conditions and are energized on relay’s tripping Positive protected version (on request): the output relays are energized on normal operating conditions, (i.e. with auxiliary supply on and input values at normal levels) and are deenergized on relay ‘s tripping, failure of power supply, internal relay fault
