Trip circuit supervision relays that continuously monitor the health and continuity of breaker trip coils and trip circuits.
Arteche F74 series Trip Circuit Supervision Relays (VDF-10, VDJ-30) ensure continuous monitoring of the trip circuit integrity of medium-voltage and high-voltage circuit breakers. These relays detect failures such as open circuits, coil disconnection, blown fuses, and wiring issues in both live and dead conditions. With fast detection and alarm outputs, the F74 series prevents protection misoperations and improves breaker reliability. Designed for harsh substation environments, the relay complies with IEC standards and offers robust immunity to vibration and electrical noise.
