SIL-A

Article: 00086454

Electromechanical relay / earth-fault / protection / over-current

Many Protection functions by default: 50P(2), 50N/G(2)(*), 50/51P, 50/51 N/G(*), 50BF, 46, 52, 79, 74TCS, COLD LOAD PICK-UP, 86, 49T . Optionally 49, 74CT, 37, 46BC, Trip Block for switch disconnector.
SIL-A adaptation B with Trip Bus protection function available through configurables inputs and outputs.
Auxiliary power supply (110-230 Vac/90-300 Vdc, 24-48 Vdc or 24-110 Vdc/48-230 Vac).
Metallic Box with high electromagnetic compatibility level (EMC) and wide range of operating temperature.
Reduced size and light weight, easy to install and saves costs.
Direct signalling/control of circuit breaker (52 function) and recloser (79 function).
To allow communication, relays have a communication port on the front of the equipment and remote communication with different options:
One rear port on the back with the following options respect to protocols:
IEC60870-103 or Modbus RTU selectable by settings
IEC 61850, DNP3.0 or IEC 60870-5-104 (depending on the model)
Two rear ports on can be used simultaneously:
ModBus RTU and IEC60870-5-103, IEC 61850, DNP 3.0 or IEC 60870-5-104.
Inputs and outputs configurable, trip circuit supervision (74TCS function).
Oscillographic records, fault reports and non-volatile RAM memory: stores multiple events with date/time even without power supply thanks to its internal RTC.
Adaptation B is fitte with the demand of current with; 168 records, circular mode of recording and sampling rate (configurable through communications from 1 to 60 minutes)
