ABB TVOC-2-240 1SFA664001R1001, ARC MONITOR, 100-240V AC/DC PWR, <1 MS ARC DETECT, 2 TRIP RLY

THE ABB TVOC-2-240 1SFA664001R1001 IS AN ARC MONITOR SYSTEM CONTROLLER ENGINEERED FOR ULTRA-FAST ARC FLASH DETECTION AND MITIGATION WITHIN ELECTRICAL SYSTEMS. THIS UNIT OPERATES ON A VERSATILE SUPPLY VOLTAGE RANGE OF 100-240 VAC/VDC. IT INTEGRATES ARC LIGHT DETECTION, ACCOMMODATING UP TO 30 CONNECTED FIBER OPTIC LOOP OR POINT SENSORS, WITH OVERCURRENT DETECTION ACHIEVED THROUGH UP TO THREE DEDICATED CURRENT TRANSFORMER INPUTS. THE CONTROLLER DETECTS ARC LIGHT IN LESS THAN 1 MILLISECOND, LEADING TO A TYPICAL TOTAL SYSTEM OPERATION TIME OF 2-5 MILLISECONDS FOR INITIATING A TRIP COMMAND. IT PROVIDES TWO INDEPENDENT TRIP RELAY OUTPUTS AND ONE ALARM RELAY OUTPUT, ALL FEATURING CHANGE-OVER CONTACTS, TO FACILITATE RAPID CIRCUIT BREAKER TRIPPING AND COMPREHENSIVE SYSTEM STATUS INDICATION UPON DETECTION OF AN ARC FAULT.
